[Bug 261891] [NEW PORT] graphics/epsonscan2: scanner engine supporting many Seiko/Epson scanners

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=261891

--- Comment #32 from J.R. Oldroyd <fbsd@opal.com> ---
A separate question...

I have not been able to get scanning with xsane to work.  Scanning with sane's
scanimage does work, though.

In debugging, I see that when xsane runs, it does do the scan: the scanner
activates and the image data is saved in the /tmp/epsonWork/_pid/ working
directory.  But then libsane-epsonscan2.so tries to run an image-enhancer
(/usr/local/lib/epsonscan2/ddeplugin) and ddeplugin wants an additional file
"EsDDE.prm" which does not exist anywhere in the distribution files I have
looked at, so ddeplugin fails.  I also cannot find EsDDE.prm anywhere by
searching.

When sane's scanimage runs, also using libsane-epsonscan.so, it apparently does
not run the ddeplugin image-enhancer.

Does anyone know how to tell xsane that the enchancer isn't needed?  I have
played with the advanced settings in xsane >> Preferences >> Setup >>
Enhancement (and other menus too, and also played with the settings in the
~/.sane/xsane/EPSON:networkscanner.drc file), but I have not yet found the knob
that turns off the enhancer.

Or, does anyone know where I can find the EsDDE.prm file?
