The function get-origin
returns the coordinate origin or pixmap-port. Normally this is (0 0) but after a series of drawing function calls with :relative t
, the drawing may have been shifted. The values returned by get-origin
tell you by how much. The values are not needed when making images from the port's drawing.
(with-pixmap-graphics-port (p1 pane width height :relative t) (with-graphics-rotation (p1 0.123) (draw-rectangle p1 0 0 200 120 :filled t :foreground :red) (get-origin p1)))
produces:
