[magick-users] Problem rotating TIFF G3

[Andreas Oster]

Dear list members,

I  have only little experience with ImageMagick and have run into a 
little problem
with a mail to FAX solution I am trying to implement. I try to send 
OpenOffice.org
documents to the server where they are converted to PDF and afterwards 
to tiffG3
with ghostscript. Everything works perfectly if the original document is 
in portrait
format. If the document is landscape I always get a blank page on the 
resceiving
FAX. So I tried to rotate the TIFF with :

mogrify -rotate 90 -compress FAX fax.tiff

The resulting TIFF also produces a blank Page on the resceiving FAX, but 
if I
view the image with an image-viewer everything seems to be ok.
What do I do wrong ? Any clues ?
