Re: [hylafax-users] Hylafax 4.1.5 and 2-D MR Wierdness

Lee/Bodo,

Thanks for your help with this. Since I have 3 50ppm Kodak
scanners, I am tied to the Kodak imaging libraries for the
foreseeable future.

I'll try hacking tiff2fax to handle the condition as noted in the bug
report.

Just in case, where would I find the libtiff 3.5.5 libraries?

Thanks!

Mike
