Slanting like that usually is the result of the lines in the image not being the expected size. Perhaps there is a compression problem going on here?

Hi Everyone, I think this was covered previously, but I've searched the archive and can't find any topics on it anymore. I'm writing a game that uses an offscreen window to blit images to the main window using a Mask image to maintain the background image of the main window. I'm using winMask followed by winOverlay to accomplish this. Everything works perfectly on OS4.0 and OS5, but on OS3.5, I get strange results. The images appear skewed (slanted) when they're drawn to the main window. Here are the steps I am using: 1) copy background image from offscreen to main window using winPaint 2) copy Mask image (black pixel = keep) from offscreen using winMask. 3) copy bitmap image from offscreen to main using winOverlay. Once again, this method works perfectly on OS4.0 and OS5. I only get strange results on OS3.5 so I suspect there is a bug in the OS relating to wincopyRectangle and transparency issues. Any help would be greatly appreciated! Thanks! __________________________________________________ Do you Yahoo!? Yahoo!
