Dear Sane people:
Thanks for your efforts. I recently obtained a used scanner with a TMA
adapter. Yours is the only software I can find that comes close to making
it work. I have a current release with the following installed under linux:
scanimage (sane-backends) 1.0.24; backend version 1.0.24
I was able to obtain images from several negatives with the scanner, but
the colors were wrong. After some experimentation I find that they are
apparently not corrected for being a negative. If for each of the 3 color
values making up each pixel in the resulting tiff output file I do:
value = 255 -value; and rewrite the file the image is corrected.
I don't have any slides yet so have not tried that, just thought you might
I have submitted one subscription request to mailing list but after several
days have not gotten a confirming email. Should I repeat the request?
Thanks again. Will
