OK, this seems like a really simple thing, but I'm not getting it. I
have an NSImage that was created from some 1-bit bitmap data using that
really long NSBitmapImageRep initWithBitmapDataPlanes... method. I need
to pad the image with a couple of pixels worth of whitespace all the
way around.
I tried:
1. create new NSImage that is 4 pixels larger in width and height;
2. lock focus on new image
3. tell original image to compositeToPoint 2,2 (also tried
dissolveToPoint and drawAtPoint)
The problem with the above is that I end up with a fuzzy looking image,
I guess due to anti-aliasing. I'm guessing (hoping?) there's a much
better / cleaner way of doing this so that I end up with the same
bitmap, just padded with some whitespace.
Thanks,
Glen Simmons
