I am (was) planning to take a Mac portable for demo purposes to CHI but
things look bad.. I'm in Copybits hell..
Drawing bitmaps into a window can be done using _copybits.
The MCL 2.0b1p3 built-in COPY-BITS function doesn't seem
to work right as most of us know. My own version, fixing the problem
(defun DRAW-BITMAP (Bitmap Window X Y &optional (Pen-Mode :patCopy))
(let* ((Topleft (make-point X Y))
(Botright (add-points topleft (rref Bitmap :Bitmap.bounds.bottomRight))))
(rlet ((dstRect :rect :topleft topleft :bottomRight botright))
(rref (wptr Window) ccl::window.portbits)
(rref Bitmap bitmap.bounds)
This worked fine on all the machines tested so far until I tested the
good ole Mac PORTABLE. I've tried several other versions of code
using copy-Bits in some form or another -> no success. I get
a blob having the correct size but random content.
IS there a known bug with the portable or just something strange that I have
H E L P.....
