spr_pal
=======
Version 2.12 (20-Aug-1993)
SPRtools block 1c release.
(C) 1993,4 DEEJ Technology PLC
Features
--------
Generates a pictorial representation of a sprites palette.
Palette images can be created in the form of a !Paint type palette,
a colour sorted bitmap, or a histogram of colour usage.
Restrictions
------------
Sorting of large sprites may take a long time to complete.
The histogram process requires a large about of memory for sprites
with many colours.
Only the first sprite in the file is recognised.
Syntax
------
spr_pal [-h] <input sprite file> <output sprite file> [<progress/error file>]
The -h option is used to produce a histogram of colour usage and may be
used for any pixel depth. Sprites with up to 8 bpp generate !Paint style
palette images, greater than 8 bpp give a sprite of the same size with
the colours sorted.
Files default to stdin and stdout with progress or errors to stderr.
Info
----
Sorting of sprite colours is by hue, if two colours have the same hue they
are sorted on intensity.
Histograms show bars of each colour sorted on hue and intensity with the
height representing the relative use of each colour. When a large number
of colours are used, ones with very small number of uses are not shown.
The bars are scaled to prevent an excessively tall sprite being produced.
