This is a fairly simple problem, but I can't seem to get it to
work...Having created a valid DIBitmap object, how do I get it to display
on the screen?
Right now I've got the following (unsucessful code) in an update method:
im = createImage(500,500);
myDisplayItem = new ImageDisplayItem(im);
myDisplayItem.setImage(myBitMap);
myDisplayItem.paint(im.win,0,0);
This code snippet seems to work fine when I substitute an image object for
myBitMap on the third line, but doesn't work when using the DIBitMap
object. Although it compiles and runs, it just sticks up a white rectangle
of size 500x500 on the screen.
What am I doing wrong?
Thanks,
Jeff Masek
