- *
- * Revision History:
- * 10-Jan-89: Created.
- * 06-Mar-90: Change to byte encoded rasterfiles.
- * fix bug in call to ReadScanline().
- * fix bug in CVT() macro.
- * fix assignment of td, (missing &).
- *
- * Description:
- * This program takes a MicroSoft/Aldus "Tagged Image File Format" image or
- * "TIFF" file as input and writes a Sun Rasterfile [see rasterfile(5)]. The
- * output file may be standard output, but the input TIFF file must be a real
- * file since seek(2) is used.
