Version 1.00 (18-Sep-2004)
SPRtools block 1i release.
(C) 2004 DEEJ Technology PLC

Features
--------
CMYK bit sprite separations generator.
Separates a sprite into four 8 bit sprites, and reassembles four sprites
into one CMYK sprite.

The four 8 bit sprites represent the cyan, magenta, yellow and key colour
separations and are named accordingly, they have 256 level grey palettes.

Restrictions
------------
Sufficient memory must be available to for all sprites to be processed.

Separating:
    There must only be one sprite in the file, it must be a CMYK sprite
    to work correctly, other types will not give useful results.

Assembling:
    There must be exactly four sprites in the file.
    The four sprites must have the same size and bpp (1-8 only).
    The sprites can be in any order but must be named cyan, magenta, yellow
    and key.

Syntax
------
spr4spr <input sprite file> <output sprite file> [<progress/error file>]

Files default to stdin and stdout with progress or errors to stderr.

Separations or assembly depends on the number of sprites in the input file.

Info
----
Separating a CMYK sprite will allow it to be edited with programs that do not
support CMYK such !Paint. Exactly the same edits must be carried out to each
of the three separations or a colour change will occur. Reassembly can be used
to rejoin a sprite after editing or to make a CMYK sprite from a program
that produces three 8 bit grey scale sprites.
