Description
Copies the pixels from the medium starting at the position specified by (medium-x,medium-y) into pixmap at the position specified by (pixmap-x,pixmap-y). A rectangle whose width and height is specified by width and height is copied. If medium is a medium or a stream, then medium-x and medium-y are transformed by the user transformation. The copying must be done by medium-copy-copy.
If pixmap is not supplied, a new pixmap will be allocated.
