+# Makefile.sources
+#
+# This file is the canonical location listing all the source files used
+# to build the cairo library.  Every source file is categorized as one of:
+#
+#   * public header file
+#   * private header file (must end in -private.h except for cairoint.h)
+#   * source code file
+#
+# Every source file should be specified exactly once, grouped with the
+# feature that uses the source file.  If more than one feature use the
+# file (like pdf_operators or font_subset files), the files should be
+# appended to to the base cairo files, and the code inside them
+# enabled/disabled using C preprocessor macros defined in cairoint.h.
+# See how pdf_operators or font_subset are handled.
+#
+# The sources are picked up according to the configured features
+# by the generated file Makefile.am.features or Makefile.win32.features.
+#
+# These are a few special source files.  Those are not included in this
+# file to not confuse build systems.  Each build system must handle them
+# separately.  These files include:
+#
+#   * cairo-features.h:
+#     This file is generated by configure and includes macros signifying
+#     which features are enabled.  This file should be installed like
+#     other public headers, but should NOT be distributed in the cairo
+#     distribution.
+#
+#   * cairo-version.h:
+#     This is a dummy header file used during the build, but it should
+#     NOT be installed.  Its sole purpose is to make sure changes in the
+#     cairo version do not trigger a full rebuild of the library, but
+#     just the functions actually using the version information.
+#
+#   * $(top_srcdir)/cairo-version.h:
+#     This is the real file holding the cairo version number.  This file
+#     should be installed like other public headers.  This is used during
+#     the build by cairo-version.c only.
+#
+#   * cairo-supported-features.h:
+#     This file is generated by configure and includes macros signifying
+#     all supported features.  This is used by gtk-doc to generate
+#     documentation for all those macros, enabled or not.
+#     This file is NOT used during the build of the library and should
+#     NOT be installed or distributed.
+#
+# Please follow the strict syntax of this file, including keeping file
+# lists sorted.
+#
+
+# BEFORE MODIFYING THIS FILE:
+#
+# This file is a descendant of an old copy of gtk-doc.make, modified for cairo minimally:
+#
+#   - Moved to build/
+#   - Made it append to EXTRA_DIST and CLEANFILES
+#   - Instead of all-local, make "doc" build docs, and err if gtk-doc not enabled
+#   - Some other changed introduced in 7f114b781f5c530d57530e5f76402e41cdabac6b
+#
+# Before changing it, check to see if a newer gtk-doc.make has fixed the issue you are facing.
+# From time to time, it would be nice to update this to the latest copy of gtk-doc.make, but
+# please do review all the differences and port our modifications forward.

+Cairo Reference Documentation
+=============================
+
+The API documentation is generated using gtk-doc.
+
+
+Building
+--------
+
+The documentation is not built by default.  To build it you need to
+configure with gtk-doc enabled (--enable-gtk-doc), and run:
+
+	make doc
+
+
+Adding New API
+--------------
+
+When adding new symbols and macros to the public API, modify
+cairo-section.txt and add new symbols to the right place.
+
+When adding whole new features, you also need to modify cairo-docs.xml
+and add a new file under tmpl/.  Beware that the files are tmpl/ are
+both manually edited AND modified by gtk-doc, gathering documentation
+stub from source files.
+
+
+Tests
+-----
+
+There are some tests in this directory, ensuring proper documentation
+syntax as well as checking that all public symbols are fully documented.
+
+After adding any new API, just run:
+
+	make check
+

+      The error handling approach in C for Cairo has multiple

+    </p>
+<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
+<li class="listitem"><p>
+	  When a method on an object fails, the object is put into
+	  an error state. Subsequent operations on the object do
+	  nothing. The status of the object can be queried with
+	  a function like <a class="link" href="cairo-cairo-t.html#cairo-status" title="cairo_status ()"><code class="function">status()</code></a>.
+      </p></li>
+<li class="listitem">
+<p>
+	  Constructors, rather than
+	  returning <code class="constant">NULL</code> on out-of-memory failure,
+	  return a special singleton object on which all
+	  operations do nothing. Retrieving the status of the
+	  singleton object returns <code class="constant">CAIRO_STATUS_NO_MEMORY</code>
+	  </p>
+<p class="remark"><em><span class="remark">
+	    Is this going to apply to
+	  <span class="type">cairo_surface_t</span> as well?
+	</span></em></p>
+<p class="remark"><em><span class="remark">
+	  What about cairo_copy_path_data()? It's probably going to
+	  have to return <code class="constant">NULL</code>.
+	</span></em></p>
+</li>
+<li class="listitem"><p>
+	  Errors propagate from object to object. Setting a pattern
+	  in an out-of-memory state as the source of a
+	  <span class="type">cairo_t</span> puts the type into an error state.
+      </p></li>
+</ul></div>
+<p class="remark"><em><span class="remark">Much of the above is not yet implemented at the time of
+      this writing</span></em></p>
+<p>
+      A language binding could copy the C approach, and for a 
+      language without exceptions, this is likely the right thing
+      to do. However, for a language with exceptions, exposing
+      a completely different style of error handling for cairo
+      would be strange. So, instead, status should be checked
+      after every call to cairo, and exceptions thrown as necessary.
+    </p>
+<p>
+      One problem that can arise with this, in languages
+      where handling exceptions is mandatory (like Java), is that almost
+      every cairo function can result in a status being set,
+      usually because of an out-of-memory condition. This could make
+      cairo hard to use. To resolve this problem, let's classify then
+      cairo status codes:
+    </p>
+<pre class="programlisting">
+/* Memory */      
+CAIRO_STATUS_NO_MEMORY,
+
+/* Programmer error */      
+CAIRO_STATUS_INVALID_RESTORE
+CAIRO_STATUS_INVALID_POP_GROUP
+CAIRO_STATUS_NO_CURRENT_POINT
+CAIRO_STATUS_INVALID_MATRIX
+CAIRO_STATUS_NO_TARGET_SURFACE
+CAIRO_STATUS_INVALID_STRING
+CAIRO_STATUS_SURFACE_FINISHED
+CAIRO_STATUS_BAD_NESTING
+
+/* Language binding implementation */
+CAIRO_STATUS_NULL_POINTER
+CAIRO_STATUS_INVALID_PATH_DATA
+CAIRO_STATUS_SURFACE_TYPE_MISMATCH
+
+/* Other */      
+CAIRO_STATUS_READ_ERROR
+CAIRO_STATUS_WRITE_ERROR
+</pre>
+<p>
+      If we look at these, the
+      <code class="constant">CAIRO_STATUS_NO_MEMORY</code>
+      should map to the native out-of-memory exception, which could
+      happen at any point in any case. Most of the others indicate
+      programmer error, and handling them in user code would be
+      silly. These should be mapped into whatever the language uses
+      for assertion failures, rather than errors that are normally
+      handled. (In Java, a subclass of Error rather than Exception,
+      perhaps.) And <code class="constant">CAIRO_STATUS_READ_ERROR</code>,
+      and <code class="constant">CAIRO_STATUS_WRITE_ERROR</code> can occur
+      only in very specific places. (In fact, as described
+      in <a class="xref" href="bindings-streams.html" title="Streams and File I/O">the section called “Streams and File I/O”</a>, these errors may be
+      mapped into the language's native I/O error types.)
+      So, there really aren't exceptions that the programmer must
+      handle at most points in the Cairo API.

+<p>
+      The objects in cairo can roughly be divided into two types:
+      reference-counted, opaque types like
+      <a class="link" href="cairo-cairo-surface-t.html#cairo-surface-t" title="cairo_surface_t"><span class="type">cairo_surface_t</span></a>
+      and plain structures like
+      <a class="link" href="cairo-text.html#cairo-glyph-t" title="cairo_glyph_t"><span class="type">cairo_glyph_t</span></a>.
+      <a class="link" href="cairo-Paths.html#cairo-path-t" title="cairo_path_t"><span class="type">cairo_path_t</span></a>
+      and 
+      <a class="link" href="cairo-Paths.html#cairo-path-data-t" title="union cairo_path_data_t"><span class="type">cairo_path_data_t</span></a>
+      are special cases and are treated separately in this appendix.
+    </p>
+<p>
+      Refcounted opaque types all have a
+      <code class="function">..._reference()</code>
+      function to increase the refcount by one and a
+      <code class="function">..._destroy()</code> to decrease the refcount
+      by one. These should not be exposed to the user of the language
+      binding, but rather used to implement memory management within
+      the language binding. The simplest way to do memory management
+      for a language binding is to treat the language binding object
+      as a simple handle to the cairo object. The language binding
+      object references the cairo object, and unreferences it when
+      finalized. This is the recommended method, though there are
+      a couple of caveats to be noted:
+    </p>
+<div class="itemizedlist"><ul class="itemizedlist" style="list-style-type: disc; ">
+<li class="listitem"><p>
+	  Equality won't work as expected. You can have two language
+	  objects for the same cairo and they won't necessarily
+	  compare equal. If the language allows customizing the
+	  equality operation, then this is fixable by comparing
+	  the underlying pointers. It also can be fixed by creating
+	  at most one language object per cairo object, and
+	  uniquifying via a <em class="firstterm">pin table</em> (a hash
+	  table that goes from cairo object to language object).
+	  For <span class="type">cairo_surface_t</span> you can use also 
+	  <a class="link" href="cairo-cairo-surface-t.html#cairo-surface-set-user-data" title="cairo_surface_set_user_data ()"><code class="function">cairo_surface_set_user_data()</code></a>
+	  instead of a separate pin table.
+	</p></li>
+<li class="listitem">
+<p>
+	  Derivation from the language object doesn't work because
+	  you can lose the language object while keeping the Cairo
+	  object. Code like:
+	</p>
+<pre class="programlisting">
+public class MySurface (ImageSurface) {
+   public MySurface (width, height) {
+      super (Format.ARGB32, width, height);
+   }
+   public int get42 () {
+      return 42;	  
+   }
+}
+
+   cr = Cairo(MySurface(width, height));
+   surface = cr.getTarget();
+</pre>
+<p>
+	  Can result in <code class="varname">surface</code> containing an
+	  <code class="classname">ImageSurface</code> not a <code class="classname">MySurface</code>.
+	  This is not easily fixable without creating memory leaks,
+	  and it's probably best to simply forbid deriving from the
+	  language objects.
+	</p>
+</li>
+</ul></div>
+<p>
+      When a plain structure is used as a return value from cairo,
+      this is done by passing it as a “out parameter”.
+    </p>
+<pre class="programlisting">
+cairo_font_extents_t extents;      
+
+cairo_font_extents (cr, &amp;extents);</pre>
+<p>
+      In a language binding, this should typically be treated
+      as a return value:
+    </p>
+<pre class="programlisting">
+FontExtents extents = cr.fontExtents ();</pre>
+<p>
+      A language binding has a choice in how it implements the
+      language objects for plain structures. It can use a pure
+      language object with fields corresponding to those of the C
+      structure, and convert from and to the C structure when calling
+      cairo functions or converting cairo return values. Or it
+      can keep a pointer to the C structure internally and wrap
+      it inside a language object much like occurs for refcounted
+      objects. The choice should be invisible to the user: they should
+      be able to imagine that it is implemented as a pure language
+      object.

+<p>
+      Function overloading (having a several variants of a function
+      with the same name and different arguments) is a language
+      feature available in many languages but not in C.
+    </p>
+<p>
+      In general, language binding authors should use restraint in
+      combining functions in the cairo API via function
+      overloading. What may seem like an obvious overload now may
+      turn out to be strange with future additions to cairo.
+      It might seem logical to make
+      <a class="link" href="cairo-cairo-t.html#cairo-set-source-rgb" title="cairo_set_source_rgb ()"><code class="function">cairo_set_source_rgb()</code></a>
+	an overload of <code class="function">cairo_set_source()</code>, but future plans to add
+	<code class="function">cairo_set_source_rgb_premultiplied()</code>,
+      which will also take three doubles make this a bad idea. For
+      this reason, only the following pairs of functions should
+      be combined via overloading
+    </p>
+<pre class="programlisting">
+void
+cairo_set_source (cairo_t *cr, cairo_pattern_t *source);
+
+void
+cairo_set_source_surface (cairo_t          *cr,
+                          cairo_surface_t  *source,
+                          double            surface_x,
+                          double            surface_y);
+      
+void
+cairo_mask (cairo_t         *cr,
+	    cairo_pattern_t *pattern);
+
+void
+cairo_mask_surface (cairo_t         *cr,
+		    cairo_surface_t *surface,
+		    double           surface_x,
+		    double           surface_y);
+      
+cairo_surface_t *
+cairo_image_surface_create (cairo_format_t	format,
+			    int			width,
+			    int			height);
+cairo_surface_t *
+cairo_image_surface_create_for_data (unsigned char	       *data,
+				     cairo_format_t		format,
+				     int			width,
+				     int			height,
+				     int			stride);
+
+cairo_status_t
+cairo_surface_write_to_png (cairo_surface_t	*surface,
+			    const char		*filename);
+
+cairo_status_t
+cairo_surface_write_to_png_stream (cairo_surface_t	*surface,
+				   cairo_write_func_t	write_func,
+				   void			*closure);
+
+cairo_surface_t *
+cairo_image_surface_create_from_png (const char	*filename);
+
+cairo_surface_t *
+cairo_image_surface_create_from_png_stream (cairo_read_func_t	read_func,
+					    void		*closure);
+    </pre>
+<p>
+      Note that there are cases where all constructors for a type
+      aren't overloaded together. For example
+      <a class="link" href="cairo-PNG-Support.html#cairo-image-surface-create-from-png" title="cairo_image_surface_create_from_png ()"><code class="function">cairo_image_surface_create_from_png()</code></a>
+      should <span class="emphasis"><em>not</em></span> be overloaded together with
+      <a class="link" href="cairo-Image-Surfaces.html#cairo-image-surface-create" title="cairo_image_surface_create ()"><code class="function">cairo_image_surface_create()</code></a>.
+      In such cases, the remaining constructors will typically need to
+      be bound as static methods. In Java, for example, we might have:
+    </p>
+<pre class="programlisting">
+Surface surface1 = ImageSurface(Format.RGB24, 100, 100);
+Surface surface2 = ImageSurface.createFromPNG("camera.png");</pre>
+<p>
+      Some other overloads that add combinations not found in C may be
+      convenient for users for language bindings that provide
+      <span class="type">cairo_point_t</span> and <span class="type">cairo_rectangle_t</span>
+      types, for example:
+    </p>
+<pre class="programlisting">
+void
+cairo_move_to (cairo_t       *cr,
+               cairo_point_t *point);
+void
+cairo_rectangle (cairo_t           *cr,

+<p>
+      The <a class="link" href="cairo-Paths.html#cairo-path-t" title="cairo_path_t"><span class="type">cairo_path_t</span></a> type is one
+      area in which most language bindings will differ significantly
+      from the C API. The C API for <span class="type">cairo_path_t</span> is
+      designed for efficiency and to avoid auxiliary objects that
+      would be have to be manually memory managed by the
+      application. However,
+      a language binding should not present <span class="type">cairo_path_t</span> as an
+      array, but rather as an opaque that can be iterated
+      over. Different languages have quite different conventions for
+      how iterators work, so it is impossible to give an exact
+      specification for how this API should work, but the type names
+      and methods should be similar to the language's mapping of the following:
+    </p>
+<pre class="programlisting">
+typedef struct cairo_path_iterator cairo_path_iterator_t;
+typedef struct cairo_path_element cairo_path_element_t;
+
+cairo_path_iterator_t *
+cairo_path_get_iterator (cairo_path_t *path);
+
+cairo_bool_t
+cairo_path_iterator_has_next (cairo_path_iterator_t *iterator);
+      
+cairo_path_element_t *
+cairo_path_iterator_next (cairo_path_iterator_t *iterator);
+
+cairo_path_element_type_t
+cairo_path_element_get_type (cairo_path_element_t *element);
+      
+void
+cairo_path_element_get_point (cairo_path_element_t *element,
+                              int                   index,
+                              double                *x,
+                              double                *y);
+    </pre>
+<p>
+      The above is written using the Java conventions for
+      iterators. To illustrate how the API for PathIterator might
+      depend on the native iteration conventions of the API, examine
+      three versions of the loop, first written in a hypothetical Java
+      binding:
+    </p>
+<pre class="programlisting">
+PathIterator iter = cr.copyPath().iterator();
+while (cr.hasNext()) {
+    PathElement element = iter.next();
+    if (element.getType() == PathElementType.MOVE_TO) {
+        Point p = element.getPoint(0);
+        doMoveTo (p.x, p.y);
+    }
+}</pre>
+<p>
+      And then in a hypothetical C++ binding:
+    </p>
+<pre class="programlisting">
+Path path = cr.copyPath();
+for (PathIterator iter = path.begin(); iter != path.end(); iter++) {
+    PathElement element = *iter;
+    if (element.getType() == PathElementType.MOVE_TO) {
+        Point p = element.getPoint(0);
+        doMoveTo (p.x, p.y);
+    }
+}</pre>
+<p>
+      And then finally in a Python binding:
+    </p>
+<pre class="programlisting">
+for element in cr.copy_path():
+    if element.getType == cairo.PATH_ELEMENT_MOVE_TO:
+        (x, y) = element.getPoint(0)
+        doMoveTo (x, y);</pre>
+<p>
+      While many of the API elements stay the same in the three

+      in C, but in an object oriented language, there should instead
+      be a hierarchy of types. (The functions that should map to
+      constructors or static methods for the various types are listed
+      after the type, methods on that type are listed below. Note that
+      cairo_pattern_create_rgb() and cairo_pattern_create_rgba()
+      should not be overloaded with each other as a SolidPattern()
+      constructor, but should appear as static methods instead.  This

+      There are a number of functions in the cairo API that have
+      multiple <em class="firstterm">out parameters</em> or
+      <em class="firstterm">in-out parameters</em>. In some languages
+      these can be translated into multiple return values. In Python,
+      what is:
+    </p>
+<pre class="programlisting">
+cairo_user_to_device (cr, &amp;x, &amp;y);</pre>
+<p>
+      can by mapped to:
+    </p>
+<pre class="programlisting">
+(x, y) = cr.user_to_device (cr, x, y);</pre>
+<p>
+      but many languages don't have provisions for multiple return
+      values, so it is necessary to introduce auxiliary types.
+      Most of the functions that require the auxiliary types
+      require a type that would, in C, look like
+    </p>
+<pre class="programlisting">
+typedef struct _cairo_point cairo_point_t;
+struct _cairo_point {
+    double x;
+    double y;
+}</pre>
+<p>
+      The same type should be used both for functions that use a pair
+      of coordinates as an absolute position, and functions that use
+      a pair of coordinates as a displacement. While an argument could
+      be made that having a separate “distance” type is more correct,
+      it is more likely just to confuse users.
+    </p>
+<pre class="programlisting">
+void
+cairo_user_to_device (cairo_t *cr, double *x, double *y);
+
+void
+cairo_user_to_device_distance (cairo_t *cr, double *dx, double *dy);

+
+void
+cairo_get_current_point (cairo_t *cr, double *x, double *y);
+    </pre>
+<p>
+      There are also a couple of functions that return four values
+      representing a rectangle. These should be mapped to a
+      “rectangle” type that looks like:
+    </p>
+<pre class="programlisting">
+typedef struct _cairo_rectangle cairo_rectangle_t;
+struct _cairo_rectangle {
+    double x;
+    double y;
+    double width;
+    double height;
+}</pre>
+<p>
+      The C function returns the rectangle as a set of two points to
+      facilitate rounding to integral extents, but this isn't worth
+      adding a “box” type to go along with the more obvious
+      “rectangle” representation.

+<p>
+      Various places in the cairo API deal with reading and writing
+      data, whether from and to files, or to other sources and
+      destinations. In these cases, what is typically provided in the
+      C API is a simple version that just takes a filename, and a
+      complex version that takes a callback function.
+      An example is the PNG handling functions:
+    </p>
+<pre class="programlisting">
+cairo_surface_t *
+cairo_image_surface_create_from_png (const char	*filename);
+
+cairo_surface_t *
+cairo_image_surface_create_from_png_stream (cairo_read_func_t read_func,
+					    void             *closure);
+
+cairo_status_t
+cairo_surface_write_to_png (cairo_surface_t	*surface,
+			    const char		*filename);
+
+cairo_status_t
+cairo_surface_write_to_png_stream (cairo_surface_t	*surface,
+				   cairo_write_func_t	write_func,
+				   void			*closure);</pre>
+<p>
+      The expectation is that the filename version will be mapped
+      literally in the language binding, but the callback version
+      will be mapped to a version that takes a language stream
+      object. For example, in Java, the four functions above
+      might be mapped to:
+    </p>
+<pre class="programlisting">
+static public ImageSurface createFromPNG (String filename) throws IOException;
+static public ImageSurface createFromPNG (InputStream stream) throws IOException;
+public void writeToPNG (String filename) throws IOException;
+public void writeToPNG (OutputStream stream) throws IOException;
+</pre>
+<p>
+      In many cases, it will be better to
+      implement the filename version internally
+      using the stream version, rather than building it on top of the
+      filename version in C. The reason for this is that will
+      naturally give a more standard handling of file errors for
+      the language, as seen in the above Java example, where
+      <code class="methodname">createFromPNG()</code> is marked as raising
+      an exception. Propagating exceptions from inside the callback
+      function to the caller will pose a challenge to the language
+      binding implementor, since an exception must not propagate
+      through the Cairo code. A technique that will be useful in
+      some cases is to catch the exception in the callback,
+      store the exception object inside a structure pointed to by
+      <em class="parameter"><code>closure</code></em>, and then rethrow it once
+      the function returns.
+    </p>
+<p class="remark"><em><span class="remark">
+      I'm not sure how to handle this for
+      <a class="link" href="cairo-PDF-Surfaces.html#cairo-pdf-surface-create-for-stream" title="cairo_pdf_surface_create_for_stream ()"><code class="function">cairo_pdf_surface_create_for_stream()</code></a>.
+      Other than keep a “exception to rethrow” thread-specific
+      variable
+      that is checked after <span class="emphasis"><em>every</em></span> call to a Cairo
+      function.

+      binding the platform-specific subtypes at all, since the
+      methods on these types are not useful without passing in native
+      C types. Unless there is a language binding for Xlib available,
+      there is no way to represent a XLib <span class="type">Display</span> * in
+      that language.
+    </p>
+<p>
+      This doesn't mean that platform-specific surface types can't
+      be used in a language binding that doesn't bind the constructor.
+      A very common situation is to use a cairo language binding in
+      combination with a binding for a higher level system like
+      the <a class="ulink" href="http://www.gtk.org/" target="_top">GTK+</a> widget
+      toolkit. In such a situation, the higher level toolkit provides
+      ways to get references to platform specific surfaces.
+    </p>
+<p>
+      The <a class="link" href="cairo-cairo-surface-t.html#cairo-surface-set-user-data" title="cairo_surface_set_user_data ()"><code class="function">cairo_surface_set_user_data()</code></a>,
+      and <a class="link" href="cairo-cairo-surface-t.html#cairo-surface-get-user-data" title="cairo_surface_get_user_data ()"><code class="function">cairo_surface_get_user_data()</code></a>
+      methods are provided for use in language bindings, and should
+      not be directly exposed to applications. One example of the use
+      of these functions in a language binding is creating a binding for:
+    </p>
+<pre class="programlisting">
+cairo_surface_t *
+<a class="link" href="cairo-Image-Surfaces.html#cairo-image-surface-create-for-data" title="cairo_image_surface_create_for_data ()"><code class="function">cairo_image_surface_create_for_data</code></a> (unsigned char	       *data,
+				     cairo_format_t		format,
+				     int			width,
+				     int			height,
+				     int			stride);
+</pre>
+<p>
+      The memory block passed in for <em class="parameter"><code>data</code></em> must be
+      kept around until the surface is destroyed, so the language
+      binding must have some way of determining when that happens. The
+      way to do this is to use the <em class="parameter"><code>destroy</code></em>
+      argument to <code class="function">cairo_surface_set_user_data()</code>.
+    </p>
+<p class="remark"><em><span class="remark">
+      Some languages may not have a suitable “pointer to a block of
+      data” type to pass in for <em class="parameter"><code>data</code></em>. And even
+      where a language does have such a type, the user will be
+      frequently able to cause the backing store to be reallocated
+      to a different location or truncated. Should we recommend a
+      standard type name and binding for a buffer object here?

+<p>Cairo uses a single status type to represent all kinds of errors.  A status
+value of <a class="link" href="cairo-Error-handling.html#CAIRO-STATUS-SUCCESS:CAPS"><code class="literal">CAIRO_STATUS_SUCCESS</code></a> represents no error and has an integer value
+of zero.  All other status values represent an error.</p>
+<p>Cairo's error handling is designed to be easy to use and safe.  All major
+cairo objects <em class="firstterm">retain</em> an error status internally which
+can be queried anytime by the users using cairo*_status() calls.  In
+the mean time, it is safe to call all cairo functions normally even if the
+underlying object is in an error status.  This means that no error handling
+code is required before or after each individual cairo function call.</p>

+<p>Resets all static data within cairo to its original state,

+<p>This function is intended to be useful when using memory-checking

+<p>WARNING: It is only safe to call this function when there are no
+active cairo objects remaining, (ie. the appropriate destroy
+functions have been called as necessary). If there are active cairo
+objects, this call is likely to cause a crash, (eg. an assertion
+failure due to a hash table being destroyed when non-empty).</p>

+<p>It is a toy API. It only offers very simple support for reading and

+<p>The behavior of <a class="link" href="cairo-Paths.html#cairo-close-path" title="cairo_close_path ()"><code class="function">cairo_close_path()</code></a> is distinct from simply calling

+<p>If there is a current point, an initial line segment will be added

+<p>The arc is circular in user space. To achieve an elliptical arc,

+<p>Emit a comment into the PostScript output for the given surface.</p>
+<p>The comment is expected to conform to the PostScript Language
+Document Structuring Conventions (DSC). Please see that manual for
+details on the available comments and their meanings. In
+particular, the %%IncludeFeature comment allows a
+device-independent means of controlling printer device features. So
+the PostScript Printer Description Files Specification will also be
+a useful reference.</p>
+<p>The comment string must begin with a percent character (%) and the
+total length of the string (including any initial percent
+characters) must not exceed 255 characters. Violating either of
+these conditions will place <em class="parameter"><code>surface</code></em>
+ into an error state. But
+beyond these two conditions, this function will not enforce
+conformance of the comment with any particular specification.</p>
+<p>The comment string should not have a trailing newline.</p>
+<p>The DSC specifies different sections in which particular comments
+can appear. This function provides for comments to be emitted
+within three sections: the header, the Setup section, and the
+PageSetup section.  Comments appearing in the first two sections
+apply to the entire document while comments in the BeginPageSetup
+section apply only to a single page.</p>
+<p>For comments to appear in the header section, this function should
+be called after the surface is created, but before a call to
+<a class="link" href="cairo-PostScript-Surfaces.html#cairo-ps-surface-dsc-begin-setup" title="cairo_ps_surface_dsc_begin_setup ()"><code class="function">cairo_ps_surface_dsc_begin_setup()</code></a>.</p>
+<p>For comments to appear in the Setup section, this function should
+be called after a call to <a class="link" href="cairo-PostScript-Surfaces.html#cairo-ps-surface-dsc-begin-setup" title="cairo_ps_surface_dsc_begin_setup ()"><code class="function">cairo_ps_surface_dsc_begin_setup()</code></a> but

+<p>For comments to appear in the PageSetup section, this function
+should be called after a call to
+<a class="link" href="cairo-PostScript-Surfaces.html#cairo-ps-surface-dsc-begin-page-setup" title="cairo_ps_surface_dsc_begin_page_setup ()"><code class="function">cairo_ps_surface_dsc_begin_page_setup()</code></a>.</p>
+<p>Note that it is only necessary to call
+<a class="link" href="cairo-PostScript-Surfaces.html#cairo-ps-surface-dsc-begin-page-setup" title="cairo_ps_surface_dsc_begin_page_setup ()"><code class="function">cairo_ps_surface_dsc_begin_page_setup()</code></a> for the first page of any
+surface. After a call to <a class="link" href="cairo-cairo-t.html#cairo-show-page" title="cairo_show_page ()"><code class="function">cairo_show_page()</code></a> or <a class="link" href="cairo-cairo-t.html#cairo-copy-page" title="cairo_copy_page ()"><code class="function">cairo_copy_page()</code></a>
+comments are unambiguously directed to the PageSetup section of the
+current page. But it doesn't hurt to call this function at the
+beginning of every page as that consistency may make the calling
+code simpler.</p>
+<p>As a final note, cairo automatically generates several comments on
+its own. As such, applications must not manually generate any of
+the following comments:</p>
+<p>Header section: %!PS-Adobe-3.0, %%Creator, %%CreationDate, %%Pages,
+%%BoundingBox, %%DocumentData, %%LanguageLevel, %%EndComments.</p>
+<p>Setup section: %%BeginSetup, %%EndSetup</p>
+<p>PageSetup section: %%BeginPageSetup, %%PageBoundingBox, %%EndPageSetup.</p>
+<p>Other sections: %%BeginProlog, %%EndProlog, %%Page, %%Trailer, %%EOF</p>

+<a name="cairo-Raster-Sources.description"></a><h2>Description</h2>
+<p>The raster source provides the ability to supply arbitrary pixel data
+whilst rendering. The pixels are queried at the time of rasterisation
+by means of user callback functions, allowing for the ultimate
+flexibility. For example, in handling compressed image sources, you
+may keep a MRU cache of decompressed images and decompress sources on the
+fly and discard old ones to conserve memory.</p>
+<p>For the raster source to be effective, you must at least specify
+the acquire and release callbacks which are used to retrieve the pixel
+data for the region of interest and demark when it can be freed afterwards.
+Other callbacks are provided for when the pattern is copied temporarily
+during rasterisation, or more permanently as a snapshot in order to keep
+the pixel data available for printing.</p>

+<p>A recording surface is a surface that records all drawing operations at
+the highest level of the surface backend interface, (that is, the
+level of paint, mask, stroke, fill, and show_text_glyphs). The recording
+surface can then be "replayed" against any target surface by using it
+as a source surface.</p>
+<p>If you want to replay a surface so that the results in target will be
+identical to the results that would have been obtained if the original
+operations applied to the recording surface had instead been applied to the
+target surface, you can use code like this:</p>
+<div class="informalexample">

+
+<p>A recording surface is logically unbounded, i.e. it has no implicit constraint
+on the size of the drawing surface. However, in practice this is rarely
+useful as you wish to replay against a particular target surface with
+known bounds. For this case, it is more efficient to specify the target
+extents to the recording surface upon creation.</p>
+<p>The recording phase of the recording surface is careful to snapshot all
+necessary objects (paths, patterns, etc.), in order to achieve
+accurate replay. The efficiency of the recording surface could be
+improved by improving the implementation of snapshot for the
+various objects. For example, it would be nice to have a
+copy-on-write implementation for _cairo_surface_snapshot.</p>

+<p>The PDF backend uses one or more rectangles to define the clickable
+area of the link.  By default cairo will use the extents of the
+drawing operations enclosed by the begin/end link tags to define the
+clickable area. In some cases, such as a link split across two
+lines, the default rectangle is undesirable.</p>
+<p><em class="parameter"><code>rect</code></em>
+: [optional] The "rect" attribute allows the application to
+specify one or more rectangles that form the clickable region.  The
+value of this attribute is an array of floats. Each rectangle is
+specified by four elements in the array: x, y, width, height. The
+array size must be a multiple of four.</p>

+,
+The <em class="parameter"><code>extents</code></em>

+.  However, if user prefers to draw in user space, they can
+achieve that by changing the matrix on <em class="parameter"><code>cr</code></em>
+.  All cairo rendering operations
+to <em class="parameter"><code>cr</code></em>
+ are permitted, however, the result is undefined if any source other
+than the default source on <em class="parameter"><code>cr</code></em>
+ is used.  That means, glyph bitmaps should
+be rendered using <a class="link" href="cairo-cairo-t.html#cairo-mask" title="cairo_mask ()"><code class="function">cairo_mask()</code></a> instead of <a class="link" href="cairo-cairo-t.html#cairo-paint" title="cairo_paint ()"><code class="function">cairo_paint()</code></a>.</p>
+<p>Other non-default settings on <em class="parameter"><code>cr</code></em>
+ include a font size of 1.0 (given that
+it is set up to be in font space), and font options corresponding to
+<em class="parameter"><code>scaled_font</code></em>
+.</p>
+<p>The <em class="parameter"><code>extents</code></em>
+ argument is preset to have <code class="literal">x_bearing</code>,
+<code class="literal">width</code>, and <code class="literal">y_advance</code> of zero,

+and <code class="literal">x_advance</code> to <code class="literal">font_extents.max_x_advance</code>.
+The only field user needs to set in majority of cases is
+<code class="literal">x_advance</code>.
+If the <code class="literal">width</code> field is zero upon the callback returning
+(which is its preset value), the glyph extents are automatically computed
+based on the drawings done to <em class="parameter"><code>cr</code></em>
+.  This is in most cases exactly what the
+desired behavior is.  However, if for any reason the callback sets the
+extents, it must be ink extents, and include the extents of all drawing
+done to <em class="parameter"><code>cr</code></em>
+ in the callback.</p>

+cluster array allocation works is similar to the glyph array.  That is,
+if <em class="parameter"><code>clusters</code></em>
+ initially points to a non-<a href="/usr/share/gtk-doc/html/glib/glib-Standard-Macros.html#NULL:CAPS"><code class="literal">NULL</code></a> value, that array may be used
+as a cluster buffer, and <em class="parameter"><code>num_clusters</code></em>
+ points to the number of cluster
+entries available there.  If the provided cluster array is too short for
+the conversion (or for convenience), a new cluster array may be allocated
+using <a class="link" href="cairo-text.html#cairo-text-cluster-allocate" title="cairo_text_cluster_allocate ()"><code class="function">cairo_text_cluster_allocate()</code></a> and placed in <em class="parameter"><code>clusters</code></em>
+.  In this case,
+the original value of <em class="parameter"><code>clusters</code></em>
+ will still be freed by the caller.  Upon
+return, <em class="parameter"><code>num_clusters</code></em>
+ should contain the number of generated clusters.
+If the value <em class="parameter"><code>clusters</code></em>
+ points at has changed after the call, the caller
+will free the allocated cluster array using <a class="link" href="cairo-text.html#cairo-text-cluster-free" title="cairo_text_cluster_free ()"><code class="function">cairo_text_cluster_free()</code></a>.</p>
+<p>The callback is optional.  If <em class="parameter"><code>num_glyphs</code></em>
+ is negative upon
+the callback returning or if the return value
+is <a class="link" href="cairo-Error-handling.html#CAIRO-STATUS-USER-FONT-NOT-IMPLEMENTED:CAPS"><code class="literal">CAIRO_STATUS_USER_FONT_NOT_IMPLEMENTED</code></a>, the unicode_to_glyph callback

+<p>Note: While cairo does not impose any limitation on glyph indices,

+assume that glyph 0 is a special glyph-not-found glyph.  User-fonts
+are advised to use glyph 0 for such purposes and do not use that

+<a name="cairo-Version-Information.description"></a><h2>Description</h2>
+<p>Cairo has a three-part version number scheme. In this scheme, we use
+even vs. odd numbers to distinguish fixed points in the software
+vs. in-progress development, (such as from git instead of a tar file,
+or as a "snapshot" tar file as opposed to a "release" tar file).</p>
+<div class="informalexample"><pre class="screen">
+ _____ Major. Always 1, until we invent a new scheme.
+/  ___ Minor. Even/Odd = Release/Snapshot (tar files) or Branch/Head (git)
+| /  _ Micro. Even/Odd = Tar-file/git
+| | /
+1.0.0
+</pre></div>
+<p>Here are a few examples of versions that one might see.</p>
+<div class="informalexample"><pre class="screen">
+Releases
+--------
+1.0.0 - A major release
+1.0.2 - A subsequent maintenance release
+1.2.0 - Another major release
+ 
+Snapshots
+---------
+1.1.2 - A snapshot (working toward the 1.2.0 release)
+ 
+In-progress development (eg. from git)
+--------------------------------------
+1.0.1 - Development on a maintenance branch (toward 1.0.2 release)
+1.1.1 - Development on head (toward 1.1.2 snapshot and 1.2.0 release)
+</pre></div>
+<div class="refsect2">
+<a name="id-1.6.4.5.6"></a><h3>Compatibility</h3>
+
+The API/ABI compatibility guarantees for various versions are as
+follows. First, let's assume some cairo-using application code that is
+successfully using the API/ABI "from" one version of cairo. Then let's
+ask the question whether this same code can be moved "to" the API/ABI
+of another version of cairo.
+
+Moving from a release to any later version (release, snapshot,
+development) is always guaranteed to provide compatibility.
+
+Moving from a snapshot to any later version is not guaranteed to
+provide compatibility, since snapshots may introduce new API that ends
+up being removed before the next release.
+
+Moving from an in-development version (odd micro component) to any
+later version is not guaranteed to provide compatibility. In fact,
+there's not even a guarantee that the code will even continue to work
+with the same in-development version number. This is because these
+numbers don't correspond to any fixed state of the software, but
+rather the many states between snapshots and releases.

+<a name="id-1.6.4.5.7"></a><h3>Examining the version</h3>
+
+Cairo provides the ability to examine the version at either
+compile-time or run-time and in both a human-readable form as well as
+an encoded form suitable for direct comparison. Cairo also provides the
+macro <a class="link" href="cairo-Version-Information.html#CAIRO-VERSION-ENCODE:CAPS" title="CAIRO_VERSION_ENCODE()"><code class="function">CAIRO_VERSION_ENCODE()</code></a> to perform the encoding.
+
+<div class="informalexample"><pre class="screen">
+Compile-time
+------------
+<a class="link" href="cairo-Version-Information.html#CAIRO-VERSION-STRING:CAPS" title="CAIRO_VERSION_STRING"><span class="type">CAIRO_VERSION_STRING</span></a>   Human-readable
+<a class="link" href="cairo-Version-Information.html#CAIRO-VERSION:CAPS" title="CAIRO_VERSION"><span class="type">CAIRO_VERSION</span></a>          Encoded, suitable for comparison
+ 
+Run-time
+--------
+<a class="link" href="cairo-Version-Information.html#cairo-version-string" title="cairo_version_string ()"><code class="function">cairo_version_string()</code></a>  Human-readable
+<a class="link" href="cairo-Version-Information.html#cairo-version" title="cairo_version ()"><code class="function">cairo_version()</code></a>         Encoded, suitable for comparison
+</pre></div>
+
+For example, checking that the cairo version is greater than or equal
+to 1.0.0 could be achieved at compile-time or run-time as follows:

+<p>Devices are the abstraction Cairo employs for the rendering system
+used by a <a class="link" href="cairo-cairo-surface-t.html#cairo-surface-t" title="cairo_surface_t"><span class="type">cairo_surface_t</span></a>. You can get the device of a surface using
+<a class="link" href="cairo-cairo-surface-t.html#cairo-surface-get-device" title="cairo_surface_get_device ()"><code class="function">cairo_surface_get_device()</code></a>.</p>
+<p>Devices are created using custom functions specific to the rendering
+system you want to use. See the documentation for the surface types
+for those functions.</p>
+<p>An important function that devices fulfill is sharing access to the
+rendering system between Cairo and your application. If you want to
+access a device directly that you used to draw to with Cairo, you must
+first call <a class="link" href="cairo-cairo-device-t.html#cairo-device-flush" title="cairo_device_flush ()"><code class="function">cairo_device_flush()</code></a> to ensure that Cairo finishes all
+operations on the device and resets it to a clean state.</p>
+<p>Cairo also provides the functions <a class="link" href="cairo-cairo-device-t.html#cairo-device-acquire" title="cairo_device_acquire ()"><code class="function">cairo_device_acquire()</code></a> and
+<a class="link" href="cairo-cairo-device-t.html#cairo-device-release" title="cairo_device_release ()"><code class="function">cairo_device_release()</code></a> to synchronize access to the rendering system
+in a multithreaded environment. This is done internally, but can also
+be used by applications.</p>
+<p>Putting this all together, a function that works with devices should
+look something like this:</p>

+The primary use of patterns is as the source for all cairo drawing
+operations, although they can also be used as masks, that is, as the
+brush too.</p>
+<p>A cairo pattern is created by using one of the many constructors,
+of the form
+<code class="function">cairo_pattern_create_<span class="emphasis"><em>type</em></span>()</code>
+or implicitly through
+<code class="function">cairo_set_source_<span class="emphasis"><em>type</em></span>()</code>
+functions.</p>

+<p>If two (or more) stops are specified with identical offset values,
+they will be sorted according to the order in which the stops are
+added, (stops added earlier will compare less than stops added
+later). This can be useful for reliably making sharp color

+<p>Create a new mesh pattern.</p>
+<p>Mesh patterns are tensor-product patch meshes (type 7 shadings in
+PDF). Mesh patterns may also be used to create other types of
+shadings that are special cases of tensor-product patch meshes such
+as Coons patch meshes (type 6 shading in PDF) and Gouraud-shaded
+triangle meshes (type 4 and 5 shadings in PDF).</p>
+<p>Mesh patterns consist of one or more tensor-product patches, which
+should be defined before using the mesh pattern. Using a mesh
+pattern with a partially defined patch as source or mask will put
+the context in an error status with a status of
+<a class="link" href="cairo-Error-handling.html#CAIRO-STATUS-INVALID-MESH-CONSTRUCTION:CAPS"><code class="literal">CAIRO_STATUS_INVALID_MESH_CONSTRUCTION</code></a>.</p>
+<p>A tensor-product patch is defined by 4 Bézier curves (side 0, 1, 2,
+3) and by 4 additional control points (P0, P1, P2, P3) that provide
+further control over the patch and complete the definition of the
+tensor-product patch. The corner C0 is the first point of the
+patch.</p>
+<p>Degenerate sides are permitted so straight lines may be used. A
+zero length line on one side may be used to create 3 sided patches.</p>
+<div class="informalexample"><pre class="screen">
+      C1     Side 1       C2
+       +---------------+

+<p>Each patch is constructed by first calling

+to specify the first point in the patch (C0). Then the sides are
+specified with calls to <a class="link" href="cairo-cairo-pattern-t.html#cairo-mesh-pattern-curve-to" title="cairo_mesh_pattern_curve_to ()"><code class="function">cairo_mesh_pattern_curve_to()</code></a> and
+<a class="link" href="cairo-cairo-pattern-t.html#cairo-mesh-pattern-line-to" title="cairo_mesh_pattern_line_to ()"><code class="function">cairo_mesh_pattern_line_to()</code></a>.</p>
+<p>The four additional control points (P0, P1, P2, P3) in a patch can
+be specified with <a class="link" href="cairo-cairo-pattern-t.html#cairo-mesh-pattern-set-control-point" title="cairo_mesh_pattern_set_control_point ()"><code class="function">cairo_mesh_pattern_set_control_point()</code></a>.</p>
+<p>At each corner of the patch (C0, C1, C2, C3) a color may be
+specified with <a class="link" href="cairo-cairo-pattern-t.html#cairo-mesh-pattern-set-corner-color-rgb" title="cairo_mesh_pattern_set_corner_color_rgb ()"><code class="function">cairo_mesh_pattern_set_corner_color_rgb()</code></a> or

+is not explicitly specified defaults to transparent black.</p>
+<p>A Coons patch is a special case of the tensor-product patch where
+the control points are implicitly defined by the sides of the
+patch. The default value for any control point not specified is the
+implicit value for a Coons patch, i.e. if no control points are
+specified the patch is a Coons patch.</p>
+<p>A triangle is a special case of the tensor-product patch where the
+control points are implicitly defined by the sides of the patch,
+all the sides are lines and one of them has length 0, i.e. if the
+patch is specified using just 3 lines, it is a triangle. If the
+corners connected by the 0-length side have the same color, the
+patch is a Gouraud-shaded triangle.</p>
+<p>Patches may be oriented differently to the above diagram. For
+example the first point could be at the top left. The diagram only
+shows the relationship between the sides, corners and control
+points. Regardless of where the first point is located, when
+specifying colors, corner 0 will always be the first point, corner
+1 the point between side 0 and side 1 etc.</p>
+<p>Calling <a class="link" href="cairo-cairo-pattern-t.html#cairo-mesh-pattern-end-patch" title="cairo_mesh_pattern_end_patch ()"><code class="function">cairo_mesh_pattern_end_patch()</code></a> completes the current
+patch. If less than 4 sides have been defined, the first missing
+side is defined as a line from the current point to the first point
+of the patch (C0) and the other sides are degenerate lines from C0
+to C0. The corners between the added sides will all be coincident
+with C0 of the patch and their color will be set to be the same as
+the color of C0.</p>
+<p>Additional patches may be added with additional calls to
+<a class="link" href="cairo-cairo-pattern-t.html#cairo-mesh-pattern-begin-patch" title="cairo_mesh_pattern_begin_patch ()"><code class="function">cairo_mesh_pattern_begin_patch()</code></a>/<a class="link" href="cairo-cairo-pattern-t.html#cairo-mesh-pattern-end-patch" title="cairo_mesh_pattern_end_patch ()"><code class="function">cairo_mesh_pattern_end_patch()</code></a>.</p>

+<p>Set the horizontal and vertical resolution for image fallbacks.</p>
+<p>When certain operations aren't supported natively by a backend,
+cairo will fallback by rendering operations to an image and then
+overlaying that image onto the output. For backends that are
+natively vector-oriented, this function can be used to set the
+resolution used for these image fallbacks, (larger values will
+result in more detailed images, but also larger file sizes).</p>
+<p>Some examples of natively vector-oriented backends are the ps, pdf,
+and svg backends.</p>
+<p>For backends that are natively raster-oriented, image fallbacks are
+still possible, but they are always performed at the native
+device resolution. So this function has no effect on those
+backends.</p>
+<p>Note: The fallback resolution only takes effect at the time of
+completing a page (with <a class="link" href="cairo-cairo-t.html#cairo-show-page" title="cairo_show_page ()"><code class="function">cairo_show_page()</code></a> or <a class="link" href="cairo-cairo-t.html#cairo-copy-page" title="cairo_copy_page ()"><code class="function">cairo_copy_page()</code></a>) so
+there is currently no way to have more than one fallback resolution

+<p>See corresponding backend surface docs for details about which MIME

+with care.</p>
+<p>Even if a backend supports a MIME type, that does not mean cairo
+will always be able to use the attached MIME data. For example, if
+the backend does not natively support the compositing operation used
+to apply the MIME data to the backend. In that case, the MIME data
+will be ignored. Therefore, to apply an image in all cases, it is best
+to create an image surface which contains the decoded image data and
+then attach the MIME data to that. This ensures the image will always
+be used while still allowing the MIME data to be used whenever
+possible.</p>

+<p>There are different subtypes of <a class="link" href="cairo-cairo-surface-t.html#cairo-surface-t" title="cairo_surface_t"><span class="type">cairo_surface_t</span></a> for

+<p>This group functionality can be convenient for performing

+<a name="cairo-text.description"></a><h2>Description</h2>
+<p>The functions with <span class="emphasis"><em>text</em></span> in their name form cairo's
+<em class="firstterm">toy</em> text API.  The toy API takes UTF-8 encoded
+text and is limited in its functionality to rendering simple
+left-to-right text with no advanced features.  That means for example
+that most complex scripts like Hebrew, Arabic, and Indic scripts are
+out of question.  No kerning or correct positioning of diacritical marks
+either.  The font selection is pretty limited too and doesn't handle the
+case that the selected font does not cover the characters in the text.
+This set of functions are really that, a toy text API, for testing and
+demonstration purposes.  Any serious application should avoid them.</p>
+<p>The functions with <span class="emphasis"><em>glyphs</em></span> in their name form cairo's
+<em class="firstterm">low-level</em> text API.  The low-level API relies on
+the user to convert text to a set of glyph indexes and positions.  This
+is a very hard problem and is best handled by external libraries, like
+the pangocairo that is part of the Pango text layout and rendering library.
+Pango is available from <a class="ulink" href="http://www.pango.org/" target="_top">http://www.pango.org/</a>.</p>

+cairo_select_font_face (<em class="parameter"><code><a class="link" href="cairo-cairo-t.html#cairo-t" title="cairo_t"><span class="type">cairo_t</span></a> *cr</code></em>,

+<p>Note: The <a class="link" href="cairo-text.html#cairo-select-font-face" title="cairo_select_font_face ()"><code class="function">cairo_select_font_face()</code></a> function call is part of what
+the cairo designers call the "toy" text API. It is convenient for
+short demos and simple programs, but it is not expected to be
+adequate for serious text-using applications.</p>
+<p>Selects a family and style of font from a simplified description as
+a family name, slant and weight. Cairo provides no operation to
+list available family names on the system (this is a "toy",
+remember), but the standard CSS2 generic family names, ("serif",
+"sans-serif", "cursive", "fantasy", "monospace"), are likely to
+work as expected.</p>
+<p>If <em class="parameter"><code>family</code></em>
+ starts with the string "<em class="parameter"><code>cairo</code></em>
+:", or if no native font
+backends are compiled in, cairo will use an internal font family.
+The internal font family recognizes many modifiers in the <em class="parameter"><code>family</code></em>
+
+string, most notably, it recognizes the string "monospace".  That is,
+the family name "<em class="parameter"><code>cairo</code></em>
+:monospace" will use the monospace version of
+the internal font family.</p>
+<p>For "real" font selection, see the font-backend-specific
+font_face_create functions for the font backend you are using. (For
+example, if you are using the freetype-based cairo-ft font backend,
+see <a class="link" href="cairo-FreeType-Fonts.html#cairo-ft-font-face-create-for-ft-face" title="cairo_ft_font_face_create_for_ft_face ()"><code class="function">cairo_ft_font_face_create_for_ft_face()</code></a> or
+<a class="link" href="cairo-FreeType-Fonts.html#cairo-ft-font-face-create-for-pattern" title="cairo_ft_font_face_create_for_pattern ()"><code class="function">cairo_ft_font_face_create_for_pattern()</code></a>.) The resulting font face
+could then be used with <a class="link" href="cairo-cairo-scaled-font-t.html#cairo-scaled-font-create" title="cairo_scaled_font_create ()"><code class="function">cairo_scaled_font_create()</code></a> and
+<a class="link" href="cairo-text.html#cairo-set-scaled-font" title="cairo_set_scaled_font ()"><code class="function">cairo_set_scaled_font()</code></a>.</p>
+<p>Similarly, when using the "real" font support, you can call
+directly into the underlying font system, (such as fontconfig or
+freetype), for operations such as listing available fonts, etc.</p>
+<p>It is expected that most applications will need to use a more
+comprehensive font handling and text layout library, (for example,
+pango), in conjunction with cairo.</p>
+<p>If text is drawn without a call to <a class="link" href="cairo-text.html#cairo-select-font-face" title="cairo_select_font_face ()"><code class="function">cairo_select_font_face()</code></a>, (nor
+<a class="link" href="cairo-text.html#cairo-set-font-face" title="cairo_set_font_face ()"><code class="function">cairo_set_font_face()</code></a> nor <a class="link" href="cairo-text.html#cairo-set-scaled-font" title="cairo_set_scaled_font ()"><code class="function">cairo_set_scaled_font()</code></a>), the default
+family is platform-specific, but is essentially "sans-serif".
+Default slant is <a class="link" href="cairo-text.html#CAIRO-FONT-SLANT-NORMAL:CAPS"><code class="literal">CAIRO_FONT_SLANT_NORMAL</code></a>, and default weight is
+<a class="link" href="cairo-text.html#CAIRO-FONT-WEIGHT-NORMAL:CAPS"><code class="literal">CAIRO_FONT_WEIGHT_NORMAL</code></a>.</p>
+<p>This function is equivalent to a call to <a class="link" href="cairo-text.html#cairo-toy-font-face-create" title="cairo_toy_font_face_create ()"><code class="function">cairo_toy_font_face_create()</code></a>

+<p>
+    While cairo is implemented and C, and has a C API, it is expected
+    that many users of cairo will be using it from languages other
+    than C. The glue that connects the core cairo library to another
+    language is known as a <em class="firstterm">language
+    binding</em>. This appendix attempts to collect together
+    issues that come up when creating a language bindings for cairo
+    and present standardized solutions to promote consistency among
+    the different language bindings.
+  </p>
+<div class="sect1">
+<div class="titlepage"><div><div><h2 class="title" style="clear: both">
+<a name="bindings-general"></a>General considerations</h2></div></div></div>
+<p>
+      The naming of the central <a class="link" href="cairo-cairo-t.html#cairo-t" title="cairo_t"><span class="type">cairo_t</span></a> type is a
+      special exception. The object is “a cairo context” not “a
+      cairo”, and names such as <span class="type">cairo_t</span> rather than
+      <span class="type">cairo_context_t</span> and
+      <code class="function">cairo_set_source()</code> rather than
+      <code class="function">cairo_context_set_source()</code> are simply
+      abbreviations to make the C API more palatable. In languages
+      which have object-oriented syntax, this abbreviation is much
+      less useful. In fact, if ‘Cairo’ is used as a namespace, then
+      in many languages, you'd end up with a ridiculous type name
+      like ‘Cairo.Cairo’. For this reason, and for inter-language
+      consistency all object-oriented languages should name this
+      type as if it were <span class="type">cairo_context_t</span>.
+    </p>
+<p>
+      The punctuation and casing of the type names and
+      method names of cairo should be changed to match the general
+      convention of the language. In Java, where type names are written
+      in StudlyCaps and method names in javaCaps, cairo_font_extents_t
+      will become FontExtents and
+      <code class="literal">cairo_set_source(cr,source)</code>,
+      <code class="literal">cr.setSource(source)</code>.
+      As compared to changing the punctuation, and casing, much
+      more reluctance should be used in changing the method names
+      themselves. Even if get is usually omitted from getters in
+      your language, you shouldn't bind cairo_get_source() as
+      cr.source().
+    </p>

+  <title>Creating a language binding for cairo</title>
+  <para>
+    While cairo is implemented and C, and has a C API, it is expected
+    that many users of cairo will be using it from languages other
+    than C. The glue that connects the core cairo library to another
+    language is known as a <firstterm>language
+    binding</firstterm>. This appendix attempts to collect together
+    issues that come up when creating a language bindings for cairo
+    and present standardized solutions to promote consistency among
+    the different language bindings.
+  </para>
+  <sect1 id="bindings-general">
+    <title>General considerations</title>
+    <para>
+      The naming of the central <link
+	linkend="cairo-t"><type>cairo_t</type></link> type is a
+      special exception. The object is “a cairo context” not “a
+      cairo”, and names such as <type>cairo_t</type> rather than
+      <type>cairo_context_t</type> and
+      <function>cairo_set_source()</function> rather than
+      <function>cairo_context_set_source()</function> are simply
+      abbreviations to make the C API more palatable. In languages
+      which have object-oriented syntax, this abbreviation is much
+      less useful. In fact, if ‘Cairo’ is used as a namespace, then
+      in many languages, you'd end up with a ridiculous type name
+      like ‘Cairo.Cairo’. For this reason, and for inter-language
+      consistency all object-oriented languages should name this
+      type as if it were <type>cairo_context_t</type>.
+    </para>
+    <para>
+      The punctuation and casing of the type names and
+      method names of cairo should be changed to match the general
+      convention of the language. In Java, where type names are written
+      in StudlyCaps and method names in javaCaps, cairo_font_extents_t
+      will become FontExtents and
+      <literal>cairo_set_source(cr,source)</literal>,
+      <literal>cr.setSource(source)</literal>.
+      As compared to changing the punctuation, and casing, much
+      more reluctance should be used in changing the method names
+      themselves. Even if get is usually omitted from getters in
+      your language, you shouldn't bind cairo_get_source() as
+      cr.source().
+    </para>
+  </sect1>
+  <sect1 id="bindings-memory">
+    <title>Memory management</title>
+    <para>
+      The objects in cairo can roughly be divided into two types:
+      reference-counted, opaque types like
+      <link
+      linkend="cairo-surface-t"><type>cairo_surface_t</type></link>
+      and plain structures like
+      <link
+	linkend="cairo-glyph-t"><type>cairo_glyph_t</type></link>.
+      <link
+	linkend="cairo-path-t"><type>cairo_path_t</type></link>
+      and 
+      <link
+	linkend="cairo-path-data-t"><type>cairo_path_data_t</type></link>
+      are special cases and are treated separately in this appendix.
+    </para>
+    <para>
+      Refcounted opaque types all have a
+      <function>..._reference()</function>
+      function to increase the refcount by one and a
+      <function>..._destroy()</function> to decrease the refcount
+      by one. These should not be exposed to the user of the language
+      binding, but rather used to implement memory management within
+      the language binding. The simplest way to do memory management
+      for a language binding is to treat the language binding object
+      as a simple handle to the cairo object. The language binding
+      object references the cairo object, and unreferences it when
+      finalized. This is the recommended method, though there are
+      a couple of caveats to be noted:
+    </para>
+    <itemizedlist>
+      <listitem>
+	<para>
+	  Equality won't work as expected. You can have two language
+	  objects for the same cairo and they won't necessarily
+	  compare equal. If the language allows customizing the
+	  equality operation, then this is fixable by comparing
+	  the underlying pointers. It also can be fixed by creating
+	  at most one language object per cairo object, and
+	  uniquifying via a <firstterm>pin table</firstterm> (a hash
+	  table that goes from cairo object to language object).
+	  For <type>cairo_surface_t</type> you can use also 
+	  <link
+	  linkend="cairo-surface-set-user-data"><function>cairo_surface_set_user_data()</function></link>
+	  instead of a separate pin table.
+	</para>
+      </listitem>
+      <listitem>
+	<para>
+	  Derivation from the language object doesn't work because
+	  you can lose the language object while keeping the Cairo
+	  object. Code like:
+	</para>
+<programlisting>
+public class MySurface (ImageSurface) {
+   public MySurface (width, height) {
+      super (Format.ARGB32, width, height);
+   }
+   public int get42 () {
+      return 42;	  
+   }
+}
+
+   cr = Cairo(MySurface(width, height));
+   surface = cr.getTarget();
+</programlisting>
+	<para>
+	  Can result in <varname>surface</varname> containing an
+	  <classname>ImageSurface</classname> not a <classname>MySurface</classname>.
+	  This is not easily fixable without creating memory leaks,
+	  and it's probably best to simply forbid deriving from the
+	  language objects.
+	</para>
+      </listitem>
+    </itemizedlist>
+    <para>
+      When a plain structure is used as a return value from cairo,
+      this is done by passing it as a “out parameter”.
+    </para>
+<programlisting>
+cairo_font_extents_t extents;      
+
+cairo_font_extents (cr, &amp;extents);</programlisting>
+    <para>
+      In a language binding, this should typically be treated
+      as a return value:
+    </para>
+<programlisting>
+FontExtents extents = cr.fontExtents ();</programlisting>
+    <para>
+      A language binding has a choice in how it implements the
+      language objects for plain structures. It can use a pure
+      language object with fields corresponding to those of the C
+      structure, and convert from and to the C structure when calling
+      cairo functions or converting cairo return values. Or it
+      can keep a pointer to the C structure internally and wrap
+      it inside a language object much like occurs for refcounted
+      objects. The choice should be invisible to the user: they should
+      be able to imagine that it is implemented as a pure language
+      object.
+    </para>
+  </sect1>
+  <sect1 id="bindings-return-values">
+    <title>Multiple return values</title>
+    <para>
+      There are a number of functions in the cairo API that have
+      multiple <firstterm>out parameters</firstterm> or
+      <firstterm>in-out parameters</firstterm>. In some languages
+      these can be translated into multiple return values. In Python,
+      what is:
+    </para>
+    <programlisting>
+cairo_user_to_device (cr, &amp;x, &amp;y);</programlisting>
+    <para>
+      can by mapped to:
+    </para>
+    <programlisting>
+(x, y) = cr.user_to_device (cr, x, y);</programlisting>
+    <para>
+      but many languages don't have provisions for multiple return
+      values, so it is necessary to introduce auxiliary types.
+      Most of the functions that require the auxiliary types
+      require a type that would, in C, look like
+    </para>
+    <programlisting>
+typedef struct _cairo_point cairo_point_t;
+struct _cairo_point {
+    double x;
+    double y;
+}</programlisting>
+    <para>
+      The same type should be used both for functions that use a pair
+      of coordinates as an absolute position, and functions that use
+      a pair of coordinates as a displacement. While an argument could
+      be made that having a separate “distance” type is more correct,
+      it is more likely just to confuse users.
+    </para>
+    <programlisting>
+void
+cairo_user_to_device (cairo_t *cr, double *x, double *y);
+
+void

+
+void
+cairo_get_current_point (cairo_t *cr, double *x, double *y);
+    </programlisting>
+    <para>
+      There are also a couple of functions that return four values
+      representing a rectangle. These should be mapped to a
+      “rectangle” type that looks like:
+    </para>
+    <programlisting>
+typedef struct _cairo_rectangle cairo_rectangle_t;
+struct _cairo_rectangle {
+    double x;
+    double y;
+    double width;
+    double height;
+}</programlisting>
+    <para>
+      The C function returns the rectangle as a set of two points to
+      facilitate rounding to integral extents, but this isn't worth
+      adding a “box” type to go along with the more obvious
+      “rectangle” representation.
+    </para>
+    <remark>
+      Q: Would it make sense here to define a standard
+      <function>cairo_rectangle_round()</function> method
+      that language bindings should map?
+    </remark>
+    <programlisting>
+void

+    <title>Overloading and optional arguments</title>
+    <para>
+      Function overloading (having a several variants of a function

+      feature available in many languages but not in C.
+    </para>
+    <para>
+      In general, language binding authors should use restraint in
+      combining functions in the cairo API via function
+      overloading. What may seem like an obvious overload now may
+      turn out to be strange with future additions to cairo.
+      It might seem logical to make
+      <link
+      linkend="cairo-set-source-rgb"><function>cairo_set_source_rgb()</function></link>
+	an overload of <function>cairo_set_source()</function>, but future plans to add
+	<function>cairo_set_source_rgb_premultiplied()</function>,
+      which will also take three doubles make this a bad idea. For
+      this reason, only the following pairs of functions should

+      Various places in the cairo API deal with reading and writing
+      data, whether from and to files, or to other sources and
+      destinations. In these cases, what is typically provided in the
+      C API is a simple version that just takes a filename, and a
+      complex version that takes a callback function.
+      An example is the PNG handling functions:
+    </para>
+<programlisting>
+cairo_surface_t *
+cairo_image_surface_create_from_png (const char	*filename);
+
+cairo_surface_t *
+cairo_image_surface_create_from_png_stream (cairo_read_func_t read_func,
+					    void             *closure);
+
+cairo_status_t
+cairo_surface_write_to_png (cairo_surface_t	*surface,

+cairo_status_t
+cairo_surface_write_to_png_stream (cairo_surface_t	*surface,
+				   cairo_write_func_t	write_func,
+				   void			*closure);</programlisting>
+    <para>
+      The expectation is that the filename version will be mapped
+      literally in the language binding, but the callback version
+      will be mapped to a version that takes a language stream
+      object. For example, in Java, the four functions above
+      might be mapped to:
+    </para>
+<programlisting>
+static public ImageSurface createFromPNG (String filename) throws IOException;
+static public ImageSurface createFromPNG (InputStream stream) throws IOException;
+public void writeToPNG (String filename) throws IOException;
+public void writeToPNG (OutputStream stream) throws IOException;
+</programlisting>
+    <para>
+      In many cases, it will be better to
+      implement the filename version internally
+      using the stream version, rather than building it on top of the
+      filename version in C. The reason for this is that will
+      naturally give a more standard handling of file errors for
+      the language, as seen in the above Java example, where
+      <methodname>createFromPNG()</methodname> is marked as raising
+      an exception. Propagating exceptions from inside the callback
+      function to the caller will pose a challenge to the language
+      binding implementor, since an exception must not propagate
+      through the Cairo code. A technique that will be useful in
+      some cases is to catch the exception in the callback,
+      store the exception object inside a structure pointed to by
+      <parameter>closure</parameter>, and then rethrow it once
+      the function returns.

+      A language binding could copy the C approach, and for a 
+      language without exceptions, this is likely the right thing
+      to do. However, for a language with exceptions, exposing
+      a completely different style of error handling for cairo
+      would be strange. So, instead, status should be checked
+      after every call to cairo, and exceptions thrown as necessary.
+    </para>
+    <para>
+      One problem that can arise with this, in languages
+      where handling exceptions is mandatory (like Java), is that almost
+      every cairo function can result in a status being set,
+      usually because of an out-of-memory condition. This could make
+      cairo hard to use. To resolve this problem, let's classify then
+      cairo status codes:
+    </para>
+<programlisting>
+/* Memory */      
+CAIRO_STATUS_NO_MEMORY,
+
+/* Programmer error */

+    <para>
+      If we look at these, the
+      <constant>CAIRO_STATUS_NO_MEMORY</constant>
+      should map to the native out-of-memory exception, which could
+      happen at any point in any case. Most of the others indicate
+      programmer error, and handling them in user code would be
+      silly. These should be mapped into whatever the language uses
+      for assertion failures, rather than errors that are normally
+      handled. (In Java, a subclass of Error rather than Exception,
+      perhaps.) And <constant>CAIRO_STATUS_READ_ERROR</constant>,
+      and <constant>CAIRO_STATUS_WRITE_ERROR</constant> can occur
+      only in very specific places. (In fact, as described
+      in <xref linkend="bindings-streams"/>, these errors may be
+      mapped into the language's native I/O error types.)

+<para>Devices are the abstraction Cairo employs for the rendering system
+used by a <link linkend="cairo-surface-t"><type>cairo_surface_t</type></link>. You can get the device of a surface using
+<link linkend="cairo-surface-get-device"><function>cairo_surface_get_device()</function></link>.</para>
+<para>Devices are created using custom functions specific to the rendering
+system you want to use. See the documentation for the surface types
+for those functions.</para>
+<para>An important function that devices fulfill is sharing access to the
+rendering system between Cairo and your application. If you want to
+access a device directly that you used to draw to with Cairo, you must
+first call <link linkend="cairo-device-flush"><function>cairo_device_flush()</function></link> to ensure that Cairo finishes all
+operations on the device and resets it to a clean state.</para>
+<para>Cairo also provides the functions <link linkend="cairo-device-acquire"><function>cairo_device_acquire()</function></link> and
+<link linkend="cairo-device-release"><function>cairo_device_release()</function></link> to synchronize access to the rendering system
+in a multithreaded environment. This is done internally, but can also
+be used by applications.</para>
+<para>Putting this all together, a function that works with devices should
+look something like this:</para>
+<informalexample><programlisting>
+void
+my_device_modifying_function (cairo_device_t *device)
+{
+  cairo_status_t status;
+
+  // Ensure the device is properly reset
+  cairo_device_flush (device);
+  // Try to acquire the device
+  status = cairo_device_acquire (device);
+  if (status != CAIRO_STATUS_SUCCESS) {
+    printf ("Failed to acquire the device: %s\n", cairo_status_to_string (status));
+    return;
+  }
+
+  // Do the custom operations on the device here.
+  // But do not call any Cairo functions that might acquire devices.
+  
+  // Release the device when done.
+  cairo_device_release (device);
+}
+</programlisting></informalexample>
+<note><para>Please refer to the documentation of each backend for
+additional usage requirements, guarantees provided, and
+interactions with existing surface API of the device functions for
+surfaces of that type.

+<para>Create a new mesh pattern.</para>
+<para>Mesh patterns are tensor-product patch meshes (type 7 shadings in
+PDF). Mesh patterns may also be used to create other types of
+shadings that are special cases of tensor-product patch meshes such
+as Coons patch meshes (type 6 shading in PDF) and Gouraud-shaded
+triangle meshes (type 4 and 5 shadings in PDF).</para>
+<para>Mesh patterns consist of one or more tensor-product patches, which
+should be defined before using the mesh pattern. Using a mesh
+pattern with a partially defined patch as source or mask will put
+the context in an error status with a status of
+<link linkend="CAIRO-STATUS-INVALID-MESH-CONSTRUCTION:CAPS"><literal>CAIRO_STATUS_INVALID_MESH_CONSTRUCTION</literal></link>.</para>
+<para>A tensor-product patch is defined by 4 Bézier curves (side 0, 1, 2,
+3) and by 4 additional control points (P0, P1, P2, P3) that provide
+further control over the patch and complete the definition of the
+tensor-product patch. The corner C0 is the first point of the
+patch.</para>
+<para>Degenerate sides are permitted so straight lines may be used. A
+zero length line on one side may be used to create 3 sided patches.</para>
+<informalexample><screen>

+<para>Each patch is constructed by first calling
+<link linkend="cairo-mesh-pattern-begin-patch"><function>cairo_mesh_pattern_begin_patch()</function></link>, then <link linkend="cairo-mesh-pattern-move-to"><function>cairo_mesh_pattern_move_to()</function></link>
+to specify the first point in the patch (C0). Then the sides are
+specified with calls to <link linkend="cairo-mesh-pattern-curve-to"><function>cairo_mesh_pattern_curve_to()</function></link> and
+<link linkend="cairo-mesh-pattern-line-to"><function>cairo_mesh_pattern_line_to()</function></link>.</para>
+<para>The four additional control points (P0, P1, P2, P3) in a patch can
+be specified with <link linkend="cairo-mesh-pattern-set-control-point"><function>cairo_mesh_pattern_set_control_point()</function></link>.</para>
+<para>At each corner of the patch (C0, C1, C2, C3) a color may be
+specified with <link linkend="cairo-mesh-pattern-set-corner-color-rgb"><function>cairo_mesh_pattern_set_corner_color_rgb()</function></link> or
+<link linkend="cairo-mesh-pattern-set-corner-color-rgba"><function>cairo_mesh_pattern_set_corner_color_rgba()</function></link>. Any corner whose color
+is not explicitly specified defaults to transparent black.</para>
+<para>A Coons patch is a special case of the tensor-product patch where
+the control points are implicitly defined by the sides of the
+patch. The default value for any control point not specified is the
+implicit value for a Coons patch, i.e. if no control points are
+specified the patch is a Coons patch.</para>
+<para>A triangle is a special case of the tensor-product patch where the
+control points are implicitly defined by the sides of the patch,
+all the sides are lines and one of them has length 0, i.e. if the
+patch is specified using just 3 lines, it is a triangle. If the
+corners connected by the 0-length side have the same color, the
+patch is a Gouraud-shaded triangle.</para>
+<para>Patches may be oriented differently to the above diagram. For
+example the first point could be at the top left. The diagram only
+shows the relationship between the sides, corners and control
+points. Regardless of where the first point is located, when
+specifying colors, corner 0 will always be the first point, corner
+1 the point between side 0 and side 1 etc.</para>
+<para>Calling <link linkend="cairo-mesh-pattern-end-patch"><function>cairo_mesh_pattern_end_patch()</function></link> completes the current
+patch. If less than 4 sides have been defined, the first missing
+side is defined as a line from the current point to the first point
+of the patch (C0) and the other sides are degenerate lines from C0
+to C0. The corners between the added sides will all be coincident
+with C0 of the patch and their color will be set to be the same as
+the color of C0.</para>
+<para>Additional patches may be added with additional calls to

+Document Structuring Conventions (DSC). Please see that manual for
+details on the available comments and their meanings. In
+particular, the %%IncludeFeature comment allows a
+device-independent means of controlling printer device features. So
+the PostScript Printer Description Files Specification will also be
+a useful reference.</para>
+<para>The comment string must begin with a percent character (%) and the
+total length of the string (including any initial percent
+characters) must not exceed 255 characters. Violating either of
+these conditions will place <parameter>surface</parameter>
+ into an error state. But
+beyond these two conditions, this function will not enforce
+conformance of the comment with any particular specification.</para>
+<para>The comment string should not have a trailing newline.</para>
+<para>The DSC specifies different sections in which particular comments
+can appear. This function provides for comments to be emitted
+within three sections: the header, the Setup section, and the
+PageSetup section.  Comments appearing in the first two sections
+apply to the entire document while comments in the BeginPageSetup
+section apply only to a single page.</para>
+<para>For comments to appear in the header section, this function should
+be called after the surface is created, but before a call to
+<link linkend="cairo-ps-surface-dsc-begin-setup"><function>cairo_ps_surface_dsc_begin_setup()</function></link>.</para>
+<para>For comments to appear in the Setup section, this function should
+be called after a call to <link linkend="cairo-ps-surface-dsc-begin-setup"><function>cairo_ps_surface_dsc_begin_setup()</function></link> but
+before a call to <link linkend="cairo-ps-surface-dsc-begin-page-setup"><function>cairo_ps_surface_dsc_begin_page_setup()</function></link>.</para>
+<para>For comments to appear in the PageSetup section, this function
+should be called after a call to
+<link linkend="cairo-ps-surface-dsc-begin-page-setup"><function>cairo_ps_surface_dsc_begin_page_setup()</function></link>.</para>
+<para>Note that it is only necessary to call
+<link linkend="cairo-ps-surface-dsc-begin-page-setup"><function>cairo_ps_surface_dsc_begin_page_setup()</function></link> for the first page of any
+surface. After a call to <link linkend="cairo-show-page"><function>cairo_show_page()</function></link> or <link linkend="cairo-copy-page"><function>cairo_copy_page()</function></link>
+comments are unambiguously directed to the PageSetup section of the
+current page. But it doesn't hurt to call this function at the
+beginning of every page as that consistency may make the calling
+code simpler.</para>
+<para>As a final note, cairo automatically generates several comments on
+its own. As such, applications must not manually generate any of
+the following comments:</para>
+<para>Header section: %!PS-Adobe-3.0, %%Creator, %%CreationDate, %%Pages,
+%%BoundingBox, %%DocumentData, %%LanguageLevel, %%EndComments.</para>
+<para>Setup section: %%BeginSetup, %%EndSetup</para>
+<para>PageSetup section: %%BeginPageSetup, %%PageBoundingBox, %%EndPageSetup.</para>

+<para>The raster source provides the ability to supply arbitrary pixel data
+whilst rendering. The pixels are queried at the time of rasterisation
+by means of user callback functions, allowing for the ultimate
+flexibility. For example, in handling compressed image sources, you
+may keep a MRU cache of decompressed images and decompress sources on the
+fly and discard old ones to conserve memory.</para>
+<para>For the raster source to be effective, you must at least specify
+the acquire and release callbacks which are used to retrieve the pixel
+data for the region of interest and demark when it can be freed afterwards.
+Other callbacks are provided for when the pattern is copied temporarily
+during rasterisation, or more permanently as a snapshot in order to keep
+the pixel data available for printing.</para>

+<para>A recording surface is a surface that records all drawing operations at
+the highest level of the surface backend interface, (that is, the
+level of paint, mask, stroke, fill, and show_text_glyphs). The recording
+surface can then be "replayed" against any target surface by using it
+as a source surface.</para>
+<para>If you want to replay a surface so that the results in target will be
+identical to the results that would have been obtained if the original
+operations applied to the recording surface had instead been applied to the
+target surface, you can use code like this:</para>
+<informalexample><programlisting>
+cairo_t *cr;
+
+cr = cairo_create (target);
+cairo_set_source_surface (cr, recording_surface, 0.0, 0.0);
+cairo_paint (cr);
+cairo_destroy (cr);
+</programlisting></informalexample>
+<para>A recording surface is logically unbounded, i.e. it has no implicit constraint
+on the size of the drawing surface. However, in practice this is rarely
+useful as you wish to replay against a particular target surface with
+known bounds. For this case, it is more efficient to specify the target
+extents to the recording surface upon creation.</para>
+<para>The recording phase of the recording surface is careful to snapshot all
+necessary objects (paths, patterns, etc.), in order to achieve
+accurate replay. The efficiency of the recording surface could be
+improved by improving the implementation of snapshot for the
+various objects. For example, it would be nice to have a
+copy-on-write implementation for _cairo_surface_snapshot.</para>

+<para>Set the horizontal and vertical resolution for image fallbacks.</para>
+<para>When certain operations aren't supported natively by a backend,
+cairo will fallback by rendering operations to an image and then
+overlaying that image onto the output. For backends that are
+natively vector-oriented, this function can be used to set the
+resolution used for these image fallbacks, (larger values will
+result in more detailed images, but also larger file sizes).</para>
+<para>Some examples of natively vector-oriented backends are the ps, pdf,
+and svg backends.</para>
+<para>For backends that are natively raster-oriented, image fallbacks are
+still possible, but they are always performed at the native
+device resolution. So this function has no effect on those
+backends.</para>
+<para>Note: The fallback resolution only takes effect at the time of
+completing a page (with <link linkend="cairo-show-page"><function>cairo_show_page()</function></link> or <link linkend="cairo-copy-page"><function>cairo_copy_page()</function></link>) so
+there is currently no way to have more than one fallback resolution
+in effect on a single page.</para>
+<para>The default fallback resoultion is 300 pixels per inch in both
+dimensions.</para>

+will always be able to use the attached MIME data. For example, if
+the backend does not natively support the compositing operation used
+to apply the MIME data to the backend. In that case, the MIME data
+will be ignored. Therefore, to apply an image in all cases, it is best
+to create an image surface which contains the decoded image data and

+lines, the default rectangle is undesirable.</para>

+<para>The functions with <emphasis>text</emphasis> in their name form cairo's
+<firstterm>toy</firstterm> text API.  The toy API takes UTF-8 encoded
+text and is limited in its functionality to rendering simple
+left-to-right text with no advanced features.  That means for example
+that most complex scripts like Hebrew, Arabic, and Indic scripts are
+out of question.  No kerning or correct positioning of diacritical marks
+either.  The font selection is pretty limited too and doesn't handle the
+case that the selected font does not cover the characters in the text.
+This set of functions are really that, a toy text API, for testing and
+demonstration purposes.  Any serious application should avoid them.</para>
+<para>The functions with <emphasis>glyphs</emphasis> in their name form cairo's
+<firstterm>low-level</firstterm> text API.  The low-level API relies on
+the user to convert text to a set of glyph indexes and positions.  This
+is a very hard problem and is best handled by external libraries, like
+the pangocairo that is part of the Pango text layout and rendering library.
+Pango is available from <ulink
+url="http://www.pango.org/">http://www.pango.org/</ulink>.</para>

+<para>Note: The <link linkend="cairo-select-font-face"><function>cairo_select_font_face()</function></link> function call is part of what
+the cairo designers call the "toy" text API. It is convenient for
+short demos and simple programs, but it is not expected to be
+adequate for serious text-using applications.</para>
+<para>Selects a family and style of font from a simplified description as
+a family name, slant and weight. Cairo provides no operation to
+list available family names on the system (this is a "toy",
+remember), but the standard CSS2 generic family names, ("serif",
+"sans-serif", "cursive", "fantasy", "monospace"), are likely to
+work as expected.</para>
+<para>If <parameter>family</parameter>
+ starts with the string "<parameter>cairo</parameter>
+:", or if no native font
+backends are compiled in, cairo will use an internal font family.
+The internal font family recognizes many modifiers in the <parameter>family</parameter>
+
+string, most notably, it recognizes the string "monospace".  That is,
+the family name "<parameter>cairo</parameter>
+:monospace" will use the monospace version of
+the internal font family.</para>
+<para>For "real" font selection, see the font-backend-specific
+font_face_create functions for the font backend you are using. (For
+example, if you are using the freetype-based cairo-ft font backend,
+see <link linkend="cairo-ft-font-face-create-for-ft-face"><function>cairo_ft_font_face_create_for_ft_face()</function></link> or
+<link linkend="cairo-ft-font-face-create-for-pattern"><function>cairo_ft_font_face_create_for_pattern()</function></link>.) The resulting font face
+could then be used with <link linkend="cairo-scaled-font-create"><function>cairo_scaled_font_create()</function></link> and
+<link linkend="cairo-set-scaled-font"><function>cairo_set_scaled_font()</function></link>.</para>
+<para>Similarly, when using the "real" font support, you can call
+directly into the underlying font system, (such as fontconfig or
+freetype), for operations such as listing available fonts, etc.</para>
+<para>It is expected that most applications will need to use a more
+comprehensive font handling and text layout library, (for example,
+pango), in conjunction with cairo.</para>
+<para>If text is drawn without a call to <link linkend="cairo-select-font-face"><function>cairo_select_font_face()</function></link>, (nor
+<link linkend="cairo-set-font-face"><function>cairo_set_font_face()</function></link> nor <link linkend="cairo-set-scaled-font"><function>cairo_set_scaled_font()</function></link>), the default
+family is platform-specific, but is essentially "sans-serif".
+Default slant is <link linkend="CAIRO-FONT-SLANT-NORMAL:CAPS"><literal>CAIRO_FONT_SLANT_NORMAL</literal></link>, and default weight is
+<link linkend="CAIRO-FONT-WEIGHT-NORMAL:CAPS"><literal>CAIRO_FONT_WEIGHT_NORMAL</literal></link>.</para>

+.  <parameter>cr</parameter>
+ is prepared such that the glyph drawing is done in
+font space.  That is, the matrix set on <parameter>cr</parameter>
+ is the scale matrix of <parameter>scaled_font</parameter>
+,
+The <parameter>extents</parameter>
+ argument is where the user font sets the font extents for
+<parameter>scaled_font</parameter>
+.  However, if user prefers to draw in user space, they can
+achieve that by changing the matrix on <parameter>cr</parameter>
+.  All cairo rendering operations
+to <parameter>cr</parameter>
+ are permitted, however, the result is undefined if any source other
+than the default source on <parameter>cr</parameter>
+ is used.  That means, glyph bitmaps should
+be rendered using <link linkend="cairo-mask"><function>cairo_mask()</function></link> instead of <link linkend="cairo-paint"><function>cairo_paint()</function></link>.</para>
+<para>Other non-default settings on <parameter>cr</parameter>

+it is set up to be in font space), and font options corresponding to
+<parameter>scaled_font</parameter>
+.</para>
+<para>The <parameter>extents</parameter>
+ argument is preset to have <literal>x_bearing</literal>,

+If the <literal>width</literal> field is zero upon the callback returning
+(which is its preset value), the glyph extents are automatically computed
+based on the drawings done to <parameter>cr</parameter>
+.  This is in most cases exactly what the
+desired behavior is.  However, if for any reason the callback sets the
+extents, it must be ink extents, and include the extents of all drawing

+<link linkend="cairo-show-text"><function>cairo_show_text()</function></link> operation.</para>
+<para>Using this callback the user-font has full control on glyphs and their

+<para>Cairo has a three-part version number scheme. In this scheme, we use
+even vs. odd numbers to distinguish fixed points in the software
+vs. in-progress development, (such as from git instead of a tar file,

+<informalexample><screen>
+ _____ Major. Always 1, until we invent a new scheme.

+| | /
+1.0.0
+</screen></informalexample>
+<para>Here are a few examples of versions that one might see.</para>
+<informalexample><screen>
+Releases
+--------
+1.0.0 - A major release
+1.0.2 - A subsequent maintenance release
+1.2.0 - Another major release
+&nbsp;
+Snapshots
+---------
+1.1.2 - A snapshot (working toward the 1.2.0 release)
+&nbsp;
+In-progress development (eg. from git)
+--------------------------------------
+1.0.1 - Development on a maintenance branch (toward 1.0.2 release)
+1.1.1 - Development on head (toward 1.1.2 snapshot and 1.2.0 release)
+</screen></informalexample>
+<refsect2>
+<title>Compatibility</title>
+
+The API/ABI compatibility guarantees for various versions are as
+follows. First, let's assume some cairo-using application code that is
+successfully using the API/ABI "from" one version of cairo. Then let's
+ask the question whether this same code can be moved "to" the API/ABI
+of another version of cairo.
+
+Moving from a release to any later version (release, snapshot,
+development) is always guaranteed to provide compatibility.
+
+Moving from a snapshot to any later version is not guaranteed to
+provide compatibility, since snapshots may introduce new API that ends
+up being removed before the next release.
+
+Moving from an in-development version (odd micro component) to any
+later version is not guaranteed to provide compatibility. In fact,
+there's not even a guarantee that the code will even continue to work
+with the same in-development version number. This is because these
+numbers don't correspond to any fixed state of the software, but
+rather the many states between snapshots and releases.
+
+</refsect2>
+<refsect2>
+<title>Examining the version</title>
+
+Cairo provides the ability to examine the version at either
+compile-time or run-time and in both a human-readable form as well as
+an encoded form suitable for direct comparison. Cairo also provides the
+macro <link linkend="CAIRO-VERSION-ENCODE:CAPS"><function>CAIRO_VERSION_ENCODE()</function></link> to perform the encoding.
+
+<informalexample><screen>
+Compile-time
+------------
+<link linkend="CAIRO-VERSION-STRING:CAPS"><type>CAIRO_VERSION_STRING</type></link>   Human-readable
+<link linkend="CAIRO-VERSION:CAPS"><type>CAIRO_VERSION</type></link>          Encoded, suitable for comparison
+&nbsp;
+Run-time
+--------
+<link linkend="cairo-version-string"><function>cairo_version_string()</function></link>  Human-readable
+<link linkend="cairo-version"><function>cairo_version()</function></link>         Encoded, suitable for comparison
+</screen></informalexample>
+
+For example, checking that the cairo version is greater than or equal
+to 1.0.0 could be achieved at compile-time or run-time as follows:
+
+<informalexample><programlisting>
+##if CAIRO_VERSION &gt;= CAIRO_VERSION_ENCODE(1, 0, 0)
+printf ("Compiling with suitable cairo version: %s\n", %CAIRO_VERSION_STRING);
+##endif
+
+if (cairo_version() &gt;= CAIRO_VERSION_ENCODE(1, 0, 0))
+    printf ("Running with suitable cairo version: %s\n", cairo_version_string ());
+</programlisting></informalexample>
