A graphics port.
A description sequence.
A boolean.
General graphics port drawing arguments.
The
draw-rectangles
function draws several rectangles as specified in
description
which consists of a group of values given as
x y
width height
. The
filled
keyword if non-
nil
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
and
mask
are used. Additionally on Unix only,
stipple, pattern
,
mask-x,
mask-y
are used.
