ArtToSpr/!ArtToSpr/!Help
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.

ArtToSpr is quite simple, so this Help file won't describe it in detail. Use
Interactive Help (!Help in your Apps folder) to find the purpose of any icon
or window.
Having said that, there are a few points that would benefit from further
explanation:
Units
-----
Dimensions in output options are given in OS units, but the size of the
sprite in the info window is given in pixels.
Scaling in conjunction with rotation
------------------------------------
Scaling always takes place after rotation, which may need to be borne in mind
when combining a rotation with inequal horizontal and vertical scale factors.
Aspect ratios
-------------
When a picture is scaled to fit a sprite of a given size it may need to be
scaled by different horizontal and vertical factors to achieve a perfect fit
(see also previous paragraph). To avoid this distortion, you can click
"Preserve aspect ratio". This will mean that the picture will probably only
fit the sprite in one direction, leaving some wasted rows or columns in the
sprite; there are 3 options for dealing with this:
Edge - Plots the picture at the bottom/left of the sprite, leaving the
blank rows at top or right.
Centre - Plots the picture in the middle of the sprite, leaving an equal
amount of blank space at each edge.
Trim - Removes the blank rows or columns, leaving the sprite smaller than
specified in one direction.
