getFromSurface

Transfers image data from a #cairo_surface_t and converts it to an RGB(A) representation inside a #GdkPixbuf. This allows you to efficiently read individual pixels from cairo surfaces. For #GdkWindows, use gdk_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.
