Watched Gary's video on creating seamless tiles but it raised a couple of questions. He does not mention snapping to a grid so that his tile will be whole pixels. It's all and good to make the nudge the same size as your rectangle/square, I get that, but how does he know that he won't have any semi-transparent (or whitish if bitmapped) pixels since he places the original square anywhere on the workspace.

The other issue is that he makes a bitmap copy. Whenever I have tried to use the bitmap copy function I get a pixelated bmp. I didn't used to get pixelated bitmap copies but one day they just started coming up all pixelated. I asked here about it and no one had an answer so I always export as PNG now. That was XX5Pro. I'll have to try it in P&GD7 and see if it's better.

Now to follow through Gary Priester's Xzone tut. Looks like that covers more of the snapping.
