  cairo_surface_t* surface,
  int src_x,
  int src_y,
  int width,
  int height
)
Description [src]
Transfers image data from a cairo_surface_t and converts it
to a GdkPixbuf.
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.
