Hi Karl
I sent a message last Wednesday, but it hasn't been reflected
by the list - it must have got stuck somewhere.
As far as Epson stuff is concerned, I noticed the problem
with xscanimage segfaulting. I was going to investigate but
apparently Oliver has helped you with this.
There is a problem with Xsane to do with the resolution
selection - this was also present in 0.1.3.
The problem is caused by some extra code that Christian
inserted into the backend to help the xscanimage resolution
slider more accurately track the actual list of scanner
resolutions.
The problem is that this extra code forces the actual
resolution to change by one value no matter what you put in,
whereas in xsane, if you are using the "resolution list", you
can go from say 75 dpi to 600 dpi in one click. Very strange
things happen when you do this (watch the image size!).
To fix this, I #ifdef'ed (is that a verb?) out the extra code
and xsane works. However, it needs more investigation. Is there
a way that the actual list of device preferred resolutions
could be used to construct the xsane resolution list?
