1998.03.13 10:10 "libtiff beta 37 fax4 bug", by Steve Robinson

Hardware:               Intel pentium 233MHZ
OS:                     Windows NT
Compiler:               VC4.2
libtiff                 version 3.4 beta 37

The Problem

Fax 4 compressed images with > 64k pixels in a scan line ( Image Width ) crash TIFFReadScanline. Images with > 64k pixels in a scan line are incorrectly compressed to Fax4 format.

Hints

When building this software the compiler points out various 32 bit to 16 bit assignments which will lose data ( eg. line 172 ) tif_fax3.c
