* Did some casts cleaning up to reduce compiler warnings in tif_fax3.c, from Bruce Carmeron <cameron@petris.com> -- modifications of changes made by Frank (sun cc still complained on cast). * Added tiffconf.h to install target per request from Bill Radcliffe <billr@corbis.com>: "We need a way for ImageMagick to know features have been compiled into the TIFF library in order to handle things properly".

|
* Revision History:
|
|
* 11-Jan-89: Created.
|
|
* 06-Mar-90: fix bug in SCALE() macro.
|
|
* got rid of xres and yres, (they weren't working anyways).
|
|
* fixed bpsl calculation.
|
|
* 25-Nov-99: y2k fix (year as 1900 + tm_year) <mike@onshore.com>

|
|
* Description:
|
|
* This program takes a Sun Rasterfile [see rasterfile(5)] as input and
|
|
* writes a MicroSoft/Aldus "Tagged Image File Format" image or "TIFF" file.
|
|
* The input file may be standard input, but the output TIFF file must be a
|
|
* real file since seek(2) is used.
