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.

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

Parameters:

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

Returns:

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