A graphics port.
A description sequence.
A boolean.
graphics-state parameters passed as keyword arguments.
The function draw-rectangles
draws several rectangles as specified in
description
which consists of a group of values given as
x y
width height
.
filled , if true, causes filled rectangles to be drawn. While the exact results are host-specific, it is intended that a filled rectangle does not include the lines (x = x+width) and (y = y+height ) while a non-filled rectangle does. This function works correctly if the port 's transform includes rotation.
The graphics-state parameters transform, foreground, background, operation, thickness, scale-thickness, dashed, dash, line-joint-style , mask, pattern, shape-mode and compositing-mode are used. Additionally on X11/Motif only, stipple is used.
