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.
