/*
** This Program created (under tremendous pressure) by Steve Berry.
**
** I hope you guys keep it clean. (If you don't, let me know :-)
**
** Status: PD all the way.
**
** What's it do? This little guy reads an Amiga IFF ILBM file and
** outputs sun rasterfile format. GIGO (Georgous In Garbage Out).
**
** USEAGE: iff2sun infile outfile
** if infile is not specified stdin is used.
** if outfile is not specified then stdout is used.
**
** Note: this program outputs a COLOR sun file with no color table,
** which defaults to shades of gray. If you want to display this on
** a monochrome tube (which is what I have) you should go through the
** folowing steps:
** 1) iff2sun inputfile outputfile
** 2) rastrepl outputfile output.bigger
** 3) rasfilter8to1 -d output.bigger output.mono
** The rastrepl just pixel replicates the image so that it large
** enough to see the detail. you can run this as many times as you
** like, but remember the image quadruples each time you use it.
** The rasfilter8to1 program converts the color file (8 bit
** planes) to mono (1 plane) and does some fancy dithering (-d).
**
** Limitations:
** Don't do HAM or ExtraHalfBright. I am planning on adding
** EHB because it would be relitively simple to do, and 64
** colors would improve the image quality for the dithering
** routines.
** Also, I have only tested this on DPaintII images, it is
** very possible that it might break with other formats.
** Unlikely, but possible :*)
