cairoSurfaceCreateSimilar: cairoSurfaceCreateSimilar

Description

Create a new surface that is as compatible as possible with an existing surface. The new surface will use the same backend as other unless that is not possible for some reason.

Usage

cairoSurfaceCreateSimilar(other, content, width, height)

Arguments

other

[CairoSurface] an existing surface used to select the backend of the new surface

content

[CairoContent] the content for the new surface

width

[integer] width of the new surface, (in device-space units)

height

[integer] height of the new surface (in device-space units)

Value

• [CairoSurface] 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.
