- * gdk_surface_create_similar_image_surface:
- * @surface: (nullable): surface to make new surface similar to, or
- *   %NULL if none
- * @format: (type int): the format for the new surface
- * @width: width of the new surface
- * @height: height of the new surface
- * @scale: the scale of the new surface, or 0 to use same as @surface
- *
- * Create a new image surface that is efficient to draw on the
- * given @surface.
- *
- * Initially the surface contents are all 0 (transparent if contents
- * have transparency, black otherwise.)
- *
- * The @width and @height of the new surface are not affected by
- * the scaling factor of the @surface, or by the @scale argument; they
- * are the size of the surface in device pixels. If you wish to create
- * an image surface capable of holding the contents of @surface you can
- * use:
- *
- * |[<!-- language="C" -->
- *   int scale = gdk_surface_get_scale_factor (surface);
- *   int width = gdk_surface_get_width (surface) * scale;
- *   int height = gdk_surface_get_height (surface) * scale;
- *
- *   // format is set elsewhere
- *   cairo_surface_t *surface =
- *     gdk_surface_create_similar_image_surface (surface,
- *                                              format,
- *                                              width, height,
- *                                              scale);
- * ]|
- *
- * Note that unlike cairo_surface_create_similar_image(), the new
- * surface's device scale is set to @scale, or to the scale factor of
- * @surface if @scale is 0.
- *
- * Returns: a pointer to the newly allocated surface. The caller
- * owns the surface and should call cairo_surface_destroy() when done
- * with it.
- *
- * This function always returns a valid pointer, but it will return a
- * pointer to a “nil” surface if @other is already in an error state
- * or any other error occurs.
