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.

Because text -extents are in user-space coordinates, they are mostly, but not -entirely, independent of the current transformation matrix. If you call -<code class="literal">cairo_scale(cr, 2.0, 2.0)</code>, text will -be drawn twice as big, but the reported text extents will not be -doubled.

Use this function -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.

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> -</div> -<div class="refsect1"> -<a name="cairo-text.functions_details"></a><h2>Functions</h2> -<div class="refsect2"> -<a name="cairo-select-font-face"></a><h3>cairo_select_font_face ()</h3> -<pre class="programlisting"><span class="returnvalue">void</span> -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>, - <em class="parameter"><code>const <span class="type">char</span> *family</code></em>, - <em class="parameter"><code><a class="link" href="cairo-text.html#cairo-font-slant-t" title="enum cairo_font_slant_t"><span class="type">cairo_font_slant_t</span></a> slant</code></em>, - <em class="parameter"><code><a class="link" href="cairo-text.html#cairo-font-weight-t" title="enum cairo_font_weight_t"><span class="type">cairo_font_weight_t</span></a> weight</code></em>);</pre> -<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.

Creating a language binding for cairo</h1></div></div></div> -<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> -</div> -</div> -<div class="footer"> -<hr>Generated by GTK-Doc V1.27</div> -</body> -</html>
