There are two possible values for a port's drawing-mode :
:qualitycauses all drawing operations to make full use of the graphics port transform . In particular, text, images and ellipses are scaled and rotated and coordinates are treated as floating point rather than being rounded to the nearest integer. It also supports anti-aliasing and alpha blending. operation is not supported in this mode, but compositing-mode is supported (see below).
:compatiblegenerates the same output as previous versions of LispWorks. Text and images are not scaled or rotated, ellipses are not rotated correctly and other shapes are drawn as if the drawing function was called with transformed coordinates
In most cases the drawing mode defaults to
so the output of your program may differ from LispWorks 6.0.
and the graphics state parameters
are all deprecated. For alternatives see copy-area added, pixblt deprecated and the sections immediately following it.
To use the old drawing mode, do for example:
(make-instance 'capi:output-pane :drawing-mode :compatible ...)
