The FAX image displays great here using recent GraphicsMagick and a recent version of development libtiff (CVS).
Hi all, my apologies if this problem has come up before - I have searched the mailing list archives but not found anything pertinent.
We have received a complaint from one of our users that our software (which utilises libtiff) is not able to properly display his fax images, although the Windows Fax Viewer is able to display them perfectly.
According to the customer these faxes are all created by "NetSatisfaxtion" fax software, although the images appear to have all been created by something called "Pixel Translations Inc, PIXTIFF".
I have placed an example problem file at http://www.gpsoft.com.au/files/tiff/bad_fax.tif
Also a screenshot of how the image appears rendered with libtiff is at http://www.gpsoft.com.au/files/tiff/no_show.png
If anyone can provide any insight into this it would be greatly appreciated!
