And: ImageMagick
And: xv
And: ???

If such a lot of tools have problems with tiff's standardly produced
by xsane, than the defaults of xsane should be changed to the solution
you are outlining below.

But: 1. I did not find any control in the xsane preferences menu
        for changing this tiff compression mode.
     2. When saving a scan (to tiff), I did not find any control
        in the save menu for changing the tiff compression mode.

Question: how to change?
