Hi, I'm using the tpu on the 3490 with backend-11-10. It works ok though the scans seem quite dark compared to the original slide. However adjusting the gamma settings on the scanned file gives a nice 1024x768 display size. I'm very much a newbie at this so sorry I can't give more detailed

Hi, I own an Epson Perfection 3490 and I am beginning to use it with the CVS version of SANE (snapscan backend). While it seems to work well at resolutions up to 1200 dpi (but I did not yet perform really thorough testing), I noticed a kind of interlacing behaviour when scanning

Hi, When you scan a DIN-A4 page with 200x200 dpi and save it e.g. as a tiff file then you get an image with about 1700 x 2200 pixels. At this point there is no relation to a size in millimeter, centimeter, inch or DIN-A3 or something like that. I don't think this is completely true. Tiff

[sane-devel] Weird snapscan firmware behaviour (bug?)

Hi, the behaviour you describe is perfectly normal, as far as the ID of the scanner is concerned. Initially the scanner identifies itself as FlatbedScanner_13. After downloading the firmware (which seems to work only in windows in your case) the scanner identifies itself as FlatbedScanner_21.

Hi, The scanner is slow in preview mode and makes a different noise (probably because it is doing very small y steps). Right now the preview mode is not the same as the normal 200 dpi mode. But this is not surprising: Somewhere around line 870 in snapscan-scsi.c you inform the scanner that

Hi, If it is always the same ratio of real distance to scanned distance (also for -l and -t) it is most likely that the calculation of the scan area is not handled correctly. That could be corrected by changing the value of pos_factor in function set_window() in snapscan-scsi.c. That
