cairo_xcb_surface_create ()

cairo_surface_t *
cairo_xcb_surface_create (xcb_connection_t *connection,
                          xcb_drawable_t drawable,
                          xcb_visualtype_t *visual,
                          int width,
                          int height);

Creates an XCB surface that draws to the given drawable. The way that colors are represented in the drawable is specified by the provided visual.

Note: If drawable is a Window, then the function cairo_xcb_surface_set_size() must be called whenever the size of the window changes.

When drawable is a Window containing child windows then drawing to the created surface will be clipped by those child windows. When the created surface is used as a source, the contents of the children will be included.

                                     int height);

Creates an XCB surface that draws to the given bitmap. This will be drawn to as a CAIRO_FORMAT_A1 object.

cairo_xcb_surface_create_with_xrender_format ()

cairo_surface_t *
cairo_xcb_surface_create_with_xrender_format
                               (xcb_connection_t *connection,

                                int height);

Creates an XCB 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_xcb_surface_set_size() must be called whenever the size of the window changes.

When drawable is a Window containing child windows then drawing to the created surface will be clipped by those child windows. When the created surface is used as a source, the contents of the children will be included.

cairo_xcb_surface_set_size ()

void
cairo_xcb_surface_set_size (cairo_surface_t *surface,
                            int width,
                            int height);

Informs cairo of the new size of the XCB drawable underlying the surface. For a surface created for a window (rather than a pixmap), this function must be called each time the size of the window changes. (For a subwindow, you are normally resizing the window yourself, but for a toplevel window, it is necessary to listen for ConfigureNotify events.)

A pixmap can never change size, so it is never necessary to call this function on a surface created for a pixmap.

If cairo_surface_flush() wasn't called, some pending operations might be discarded.

cairo_xcb_surface_set_drawable ()

void
cairo_xcb_surface_set_drawable (cairo_surface_t *surface,
                                xcb_drawable_t drawable,

                                int height);

Informs cairo of the new drawable and size of the XCB drawable underlying the surface.

If cairo_surface_flush() wasn't called, some pending operations might be discarded.

                                int minor_version);

Restricts all future XCB surfaces for this devices to the specified version of the RENDER extension. This function exists solely for debugging purpose. It let's you find out how cairo would behave with an older version of the RENDER extension.

Use the special values -1 and -1 for disabling the RENDER extension.

                                int minor_version);

Restricts all future XCB surfaces for this devices to the specified version of the SHM extension. This function exists solely for debugging purpose. It let's you find out how cairo would behave with an older version of the SHM extension.

Use the special values -1 and -1 for disabling the SHM extension.

Render supports two modes of precision when rendering trapezoids. Set the precision to the desired mode.
