pixbuf_get_from_surface

Description:

public Pixbuf? pixbuf_get_from_surface (Surface surface, int src_x, int src_y, int width, int height)

Transfers image data from a XlibSurface and converts it to an RGB(A) representation inside a Pixbuf.

This allows you to efficiently read individual pixels from cairo surfaces. For Windows, use pixbuf_get_from_window instead.

This function will create an RGB pixbuf with 8 bits per channel. The pixbuf will contain an alpha channel if the surface contains one.

surface	surface to copy from
src_x	Source X coordinate within `surface`
src_y	Source Y coordinate within `surface`
width	Width in pixels of region to get
height	Height in pixels of region to get

A newly-created pixbuf with a reference count of 1, or null on error
