The new graphics state parameter text-mode controls the mode of rendering text, most importantly anti-aliasing. To draw text without anti-aliasing use:
(gp:draw-string pane string x y :text-mode :plain)
To draw text the way it would be drawn if
drawing-mode
was
:compatible
, use:
(gp:draw-string pane string x y :text-mode :compatible)
The new graphics state parameter shape-mode controls the mode of drawing shapes, that is anything except text. For example to draw a rectangle without anti-aliasing use:
(gp:draw-rectangle pane x y w h :shape-mode :plain)
Currently
text-mode
and
shape-mode
are supported only when the
drawing-mode
is
:quality
, described in Quality drawing. For further details see the manual page for
gp:graphics-state
.
