gdk-pixbuf-copy-area (src xsrc ysrc width height dest xdest ydest)

src -- a gdk-pixbuf object
xsrc -- an integer with the source x coordinate within src
ysrc -- an integer with the source y coordinate within src
width -- an integer with the width of the area to copy
height -- an integer with the height of the area to copy
dest -- a gdk-pixbuf destination object
xdest -- an integer with the x coordinate within dest
ydest -- an integer with the y coordinate within dest

Copies a rectangular area from src to dest. Conversion of pixbuf formats is done automatically.

If the source rectangle overlaps the destination rectangle on the same pixbuf, it will be overwritten during the copy operation. Therefore, you can not use this function to scroll a pixbuf.
