This program takes a AMIGA IFF ILBM file and converts it to a SIXEL file
to be displayed on DIGITAL EQUIPMENT CORP. VT240, VT241, VT340
terminals.
This version will handle only 16 colors for a VT340 and 4 colors for a
VT240. It does no color compression, so all input files must be 16
colors or less for a 340, 4 colors or less for a 240. Or, up to 64
colors for a printer.
If the display is a VT240/241 then the resolution is set to 640X200. If
it's a 340 then the res is 640X400. PRINT gives a straight pixel for
pixel representation.
I tried to make it a generic as possible so you can compile it under
what ever environment you please. If you do it under VMS you will need
to define IFF2SIXEL as a foreign command i.e. $ iff2sixel :==
$mydir:iff2sixel otherwise you can't use command line args.
#!/bin/sh
# This is a shell archive. Remove anything before this line, then unpack

# will see the following message at the end:

X Program : IFF2SIXEL.C
X
X Author : Tony Kennedy
X Internet address: kennedam%wwps@dupont.com@relay.cs.net
X
X Purpose : This program takes a AMIGA IFF ILBM file and converts
X it to a SIXEL file to be displayed on DIGITAL EQUIPMENT
X CORP. VT240, VT241, VT340 terminals.
X
X This version will handle only 16 colors for a VT340 and
X 4 colors for a VT240. It does no color compression, so
X all input files must be 16 colors or less for a 340,
X 4 colors or less for a 240. Or, up to 64 colors for a
X printer.
X
X If the display is a VT240/241 then the resolution
X is set to 640X200. If it's a 340 then the res is 640X400.
X PRINT gives a straight pixel for pixel representation.
X
X I tried to make it a generic as possible so you can
X compile it under what ever environment you please.
X If you do it under VMS you will need to define IFF2SIXEL
X as a foreign command i.e. $ iff2sixel :== $mydir:iff2sixel
X otherwise you can't use command line args.
X
X Usage : iff2sixel <input_file> <output_file> <VT240 | VT340 | PRINT>
X
X Comments : This program is Freely Distributable. You may
X use it for any non-commercial uses.
X (If anybody hacks at this please send me a copy.)
X
X Acknowledgements : Thanks to...
X
X Carter Brock for the SHOW_IFF program I used
X to figure out how to read an IFF file.
X
X Mark Thompson and Steve Berry for the IFF2SUN
X program I used to figure out how to interpret
X the bitplanes.
X
X Barry Young for his help with SIXEL formats.
X
X Daniel Jay Barrett for his switching bytes
X hacks.
X
X All the people at Dupont who tested it on
X their pictures. (Hi Mike!)
X
X Limitations : This won't do HAM. When I figure it out
X I'll put that in too.
X Won't do any color compression.
X I had some trouble getting this to run on the Amiga.
X It needs a REALLY big stack. Next time I rewrite it,
X I'll do something about that.
X
X Versions: Revisions :
X
X 1.0 3/1/89 Original program.
X 1.1 5/5/89 Modified to read Deluxe Paint III files.
X More robust IFF header read routines.
X 1.2 7/14/89 Changed Argument line routine.
X Changed SixelLine Array to do one line at
X a time instead of the whole thing at once.
X Added #define H_LINES, V_LINES, N_COLORS
X Changed all unsigned short to short.
X 1.21 4/4/90 Added Halfbrite, overscan, 7 bit control codes.
X Checks for PAL. Printer codes for LJ250 ink jet
X printer.
