Method

GdkSurfacecreate_similar_surface

Declaration [src]

cairo_surface_t*
gdk_surface_create_similar_surface (
  GdkSurface* surface,
  cairo_content_t content,
  int width,
  int height
)

Description [src]

Create a new Cairo surface that is as compatible as possible with the given surface.

For example the new surface will have the same fallback resolution and font options as surface. Generally, the new surface will also use the same backend as surface, unless that is not possible for some reason. The type of the returned surface may be examined with cairo_surface_get_type().

Initially the surface contents are all 0 (transparent if contents have transparency, black otherwise.)

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.

Parameters

`content`	`cairo_content_t`
	The content for the new surface.
`width`	`int`
	Width of the new surface.
`height`	`int`
	Height of the new surface.

Return value

Returns:	`cairo_surface_t`
	A pointer to the newly allocated surface. The caller owns the surface and should call `cairo_surface_destroy()` when done with it.
	The caller of the method takes ownership of the data, and is responsible for freeing it.
