RG8.EXE by Bob Montgomery Last Update 9-1-88
This is a program for converting RIX satellite picture to GIF format for ease
of distribution and viewing on the widest range of computers. Entering RG8
alone gives the following help message.
Format is: RG8 filename[.ext] [/i] [/2] [/rxxx] [/cyyy] [/p[s]]
where the extension RIX is assumed with 640 columns by 480 rows.
The /i gives an interlaced GIF file, and /2 gives a half size file.
The /p option loads an external palette file and does color at 8 bits/pixel.
The default is filename.pal, and the s suffix loads stdpal.pal for CRIX data.
Without /p option, does 64 shades of grey, uses 6 bits/pixel, auto contrast.
The /r and /c options allow other than RIX format files to be processed, where
/rxxx => xxx rows, and /cyyy => yyy columns in the raw data file.
Thus to do a 64 grey shade VAS file enter rg8 filename.vas /r401 /c512
which could be done from a batch file with rg8 %1.vas /r401 /c512 %2 %3 %4
The 64 shades of grey VGA picture which shows excellent detail when viewed with
one of the extended VGA cards, like the Orchid Designer, STB, or Paradise. To
view on standard VGA (320x200) use the /2 option. The /p color option is for
experimenting with color GIFs, and the s suffix loads a standard palette which
is correct for R-G-B data files combined to a RIX file with CRIX (which is
available as a seperate download, as is 2x0602.ARC which has R-G-B raw data).
The program requires at least 512K of memory to do /i or /2 options.
If you use the program regularly, please register it by sending $10 to

This will encourage me to update it periodically, and respond to registered
user's requests for new features. If there is no support, I can't get too
excited about changes or adding new features.
