Purpose : Compress or decompress 4 and 8 bit OS/2 bitmaps.
Target : OS/2 2.1 beta (6.479)
Usage : BMPCMP <options> <x> <y>
<options> -d = decompress
-c = compress
-v = verbose
<x> = input bitmap name
<y> = output bitmap name
What to expect :
----------------
BMPCMP will not work on bitmap files which contain more than 1 image.
BMPCMP will not attempt to compress images whose width < 16.
BMPCMP outputs all files in the BITMAPARRAYFILEHEADER2 format.
BMPCMP cannot compress or decompress 1 bit, 24 bit or multi-plane
bitmaps.
The OS/2 2.1 (6.479) ICONEDIT.EXE cannot read bitmaps compressed
with BMPCMP.
BMPCMP will not compress the bitmap data if the size of the bitmap
data would become larger. The overall size of the bitmap _may_
increase however. i.e. some 1.x 8 bit bitmaps with poor
compressability.
Notes :
-------
R0.01 - Fixed errors in RLE4 and RLE8 compression code.
- The program will no longer just beep if an error
occurs in compression or decompression. The reason
for the error will be displayed.
- MIN_COMPRESS_WIDTH was reduced to 16 from 64.
