Package: cairo
Function cairo:surface-create-similar
Lambda Listcairo:surface-create-similar (target content width height) ArgumentsReturn Value The newly allocated cairo:surface-t instance. The caller owns the surface and should call the cairo:surface-destroy function when done
with it. This function always returns a valid surface, but it will return a "nil" surface if target is already in an error state or any other
error occurs. Details
Create a new surface that is as compatible as possible with an existing
surface.
For example the new surface will have the same fallback resolution and font options as target. Generally, the new surface will also use the same backend as target, unless that is not possible for some reason. The type of the returned surface may be examined with the cairo:surface-type
function. Initially the surface contents are all 0 and transparent if contents have transparency, black otherwise. Use the cairo:surface-create-similar-image function if you need an image surface which can be painted quickly to the target surface. | See also |
