Renders a rectangular portion of a pixbuf to a drawable. The destination drawable must have a colormap. All windows have a colormap, however, pixmaps only have colormap by default if they were created with a non-0 window argument. Otherwise a colormap must be set on them with Gdk::Drawable::set_colormap().

On older X servers, rendering pixbufs with an alpha channel involves round trips to the X server, and may be somewhat slow.

The clip mask of gc is ignored, but clip rectangles and clip regions work fine.

Since: 2.2

gc A Gdk::GC, used for clipping, or 0.
pixbuf A Gdk::Pixbuf.
src_x Source X coordinate within pixbuf.
src_y Source Y coordinates within pixbuf.
dest_x Destination X coordinate within drawable.
dest_y Destination Y coordinate within drawable.
width Width of region to render, in pixels, or -1 to use pixbuf width.
height Height of region to render, in pixels, or -1 to use pixbuf height.
dither Dithering mode for Gdk::RGB.
x_dither X offset for dither.
y_dither Y offset for dither.
