Note that the XLib surface automatically takes advantage of X Render extension if it is available. cairo_xlib_surface_create_with_xrender_format cairo_surface_t * cairo_xlib_surface_create_with_xrender_format (Display *dpy, Drawable drawable, Screen *screen, XRenderPictFormat *format, int width, int height); Creates an Xlib surface that draws to the given drawable. The way that colors are represented in the drawable is specified by the provided picture format. Note: If drawable is a Window, then the function cairo_xlib_surface_set_size() must be called whenever the size of the window changes. dpy an X Display drawable an X Drawable, (a Pixmap or a Window) screen the X Screen associated with drawable format the picture format to use for drawing to drawable . The depth of format must match the depth of the drawable. width the current width of drawable . height the current height of drawable . the newly created surface Since: 1.0 cairo_xlib_surface_get_xrender_format XRenderPictFormat * cairo_xlib_surface_get_xrender_format (cairo_surface_t *surface); Gets the X Render picture format that surface uses for rendering with the X Render extension. If the surface was created by cairo_xlib_surface_create_with_xrender_format() originally, the return value is the format passed to that constructor. surface an xlib surface the XRenderPictFormat* associated with surface , or NULL if the surface is not an xlib surface or if the X Render extension is not available. Since: 1.6 CAIRO_HAS_XLIB_XRENDER_SURFACE #define CAIRO_HAS_XLIB_XRENDER_SURFACE 1 Defined if the XLib/XRender surface functions are available. This macro can be used to conditionally compile backend-specific code. Since: 1.6 cairo_surface_t
