PD/SprShift/!SprShift/Help_html

This website contains an archive of files for the Acorn Electron, BBC Micro, Acorn Archimedes, Commodore 16 and Commodore 64 computers, which Dominic Ford has rescued from his private collection of floppy disks and cassettes.

Some of these files were originally commercial releases in the 1980s and 1990s, but they are now widely available online. I assume that copyright over them is no longer being asserted. If you own the copyright and would like files to be removed, please contact me.

<h1><img src="!Sprites22">!SprShift</h1>

<p>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.<p>


<h3>It works in this way:</h3>

<p>Suppose you divide your bitmap into quarters. When tiled it looks like this:
<p><img src="grid1">
<p>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.
<p>That's it. Simply fire up <strong>!SprShift</strong>, drag a sprite file onto it's icon and save it
where you will.<br>It probably isn't necessary but if you want the original image back run
it through again.

<p><strong>!SprShift</strong> is freeware, I retain the copyright, so no fiddling with it. It is currently
version 0.90 but already has a <a href="history">History</a>. There are
also <a href="history#limits">Limitations</a> encompassing both stuff I can't be bothered to do
and stuff I might do.

<hr size=2>
<p><admonishments>Disclaimer:
<br>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.....</admonishments>
