[sane-devel] Epson Perfection 1260 TPU again?

[Gerhard Jaeger]

Hi, although the negative scans are far from perfect, I've checked it
here with latest CVS stuff and have no stripes...

My problem is, that I'm not sure how to setup the various parameters,
or to filter the image data that the colors of a negative are correct.
I asked the list a couple of weeks ago for help, but got no response
so far...

ciao,
  Gerhard
