32 * Revision History:
33 * 11-Jan-89: Created.
34 * 06-Mar-90: fix bug in SCALE() macro.
35 * got rid of xres and yres, (they weren't working anyways).
36 * fixed bpsl calculation.
37 * 25-Nov-99: y2k fix (year as 1900 + tm_year) <mike@onshore.com>
38 *
39 * Description:
40 * This program takes a Sun Rasterfile [see rasterfile(5)] as input and
41 * writes a MicroSoft/Aldus "Tagged Image File Format" image or "TIFF" file.
42 * The input file may be standard input, but the output TIFF file must be a
43 * real file since seek(2) is used.
