create_similar_surface

Description:

[ Version ( since = "2.22" ) ]
public Surface create_similar_surface (Content content, int width, int height)

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

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

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

Parameters:

this	window to make new surface similar to
content	the content for the new surface
width	width of the new surface
height	height of the new surface

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.
