!SprShift

Creating background bitmaps for backdrops or web pages can be awkward because when tiled the edges of the bitmap end tend to show up. This program rearranges the sprites in a sprite file so that these artifices may be edited away.

It works in this way:

Suppose you divide your bitmap into quarters. When tiled it looks like this:

If we rearranged our sprite to what we have in the red box we have the edges running down the centre and can edited then out.

That's it. Simply fire up !SprShift, drag a sprite file onto it's icon and save it where you will.
It probably isn't necessary but if you want the original image back run it through again.

!SprShift is freeware, I retain the copyright, so no fiddling with it. It is currently version 0.90 but already has a History. There are also Limitations encompassing both stuff I can't be bothered to do and stuff I might do.

Disclaimer:
In an infinite universe anything is possible. You use this application at your own risk so don't blame me if it all goes pear shaped. That said, I don't see how it could. It's only shifting around bitmaps for God's sake.....
