createSimilarSurface
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.
Return
a pointer to the newly allocated surface. The caller owns the surface and should call cairo_surface_destroy() when done with it.
Parameters
the content for the new surface
width of the new surface
height of the new surface
