[Gimp-developer] Scanner Epson FS200 negs wrong pixel line SUGGESTIONS
Hi All, I have a problem with a Epson FS200 Slide/negs Scanner. The problem is more obvious with negatives than with slides. The problem is that I always get one of the pixels in the negs more clearer than the rest of them (i.e. a white line crossing the scanned negative). In the case of the slides the line is darker than the rest of the scanned slide. Scanner is out of warranty. First thing I have tried was to clean the lens just in case but, it did not solved the problem. I do not want to go deeper in cleaning it just in case I spoil the alignment of the lens. I use gimp/sane to scan slides. I tested the scanner also at win9x to see if it could be a problem of the soft but the offending pixels were there too. I was thinking of editing negs/slides, but it is going to be a long and tedious work. The failure in the case of slides is almost unperceptible. Negatives is really obvious. The question: Have gimp some special feature so that if I am able to identify the pixel line (supposing it is always at the same position) I could apply a script to correct the pixel line ? My idea is this (supposing an horizontal pixels line): the offending pixel line would be corrected to the value of the pixel above and/or the pixel below it (like an interpolation between the pixels above and below the wrong line of pixels). I am not sure if I am said something really with nonsense. I would appreciate some ideas about how to proceed.

Well, if it's _always_ in the same position, could I recommend creating a selection based on that pixel information, rotating the image, selecting a small selection around it and doing deinterlace? Should be quite easy to script with Gimp-Perl, given that it's exactly in the same spot.
