Actually, no. This would only work for the first file that you
scanned, right? Then one would have to restart xscanimage for each
new scan. For my slow PINT backend, I want to avoid such a process.

The biggest use of a `postview' window would be a to be able to see
each scan attempt until one got it right.

But, the more I think about it, the more it seems that such an option
would be just too hard to make generic. Even having a `postprocess'
preference would be too hard to get right.

I guess the current workflow:

xscanimage&
xv out.ppm&
# Reload out.ppm each time it changes by hitting <enter> on XV.

is just fine, unless anybody has any other bright ideas.

Thanks anyway for your comments,
