Re: wmaker TIFF (actually libtiff4) problem
I have tried to fix the wmaker problem but get stuck

Although I don't know much about TIFF files, I ran
tiffinfo on two systems. The target TIFF file is
/usr/X11R6/share/WINGs/Images.tiff in cygwin
WindowMaker distribution.
On the problematic cygwin (WindowMaker-0.80.2-1,
tiff-3.6.0-5) the output is:
TIFFReadDirectory: Warning, /usr/X11R6/share/WINGs/Images.tiff: unknown field wi
th tag 317 (0x13d) encountered.
TIFF Directory at offset 0x449c
Image Width: 128 Image Length: 128
Resolution: 72, 72 pixels/inch
Bits/Sample: 8
Compression Scheme: LZW
Photometric Interpretation: RGB color
Extra Samples: 1<assoc-alpha>
FillOrder: lsb-to-msb

Images.tiff"
Image Description: "Created with The GIMP"

On a FreeBSD 4.8 system, the output is:
TIFF Directory at offset 0x449c

The differences are the warning and the last line.
The 'Compression Scheme' field indicates LZW.
Is this relevant to the problem?
