Method Cairo.Surface()->finish()

Method finish

void finish()

Description

This function finishes the surface and drops all references to external resources. For example, for the Xlib backend it means that cairo will no longer access the drawable, which can be freed. After calling finish() the only valid operations on a surface are checking status, getting and setting user, referencing and destroying, and flushing and finishing it. Further drawing to the surface will not affect the surface but will instead trigger a STATUS_SURFACE_FINISHED error.

When the reference count of the Surface decreases to zero, cairo will call finish() if it hasn't been called already, before freeing the resources associated with the surface.
