Description
Returns a pixmap for the specified medium. This function is called by with-output-to-pixmap and returns the pixmap that is operated on. If you are subclassing <medium>, you must define new methods on this function.
The width and height are integers that give the width and height of the pixmap. If they are unsupplied, the result pixmap will be large enough to contain all of the output done by the body of code executed by with-output-to-pixmap.
