getFromSurface

Transfers image data from a cairo_surface_t and converts it to an RGB(A) representation inside a gdk.Pixbuf This allows you to efficiently read individual pixels from cairo surfaces. For gdk.Windows, use Pixbuf.getFromWindow 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.
