We are trying to get an Epson Perfection 2480 Photo to use custom gamma. The command line arguments and error message returned are below. The scanner seems to be working otherwise.
Also, is there a way to hardcode, say through a symlink or something, a static name for the device so it doesn't always change each time we unplug/plug it. As it stands now we have to change the device name in our application if the scanner has been unplugged or powered off. scanimage --device snapscan:libusb:001:010 --mode Color --resolution 600 -x 216 -y 279 --custom-gamma="yes" --red-gamma-table "[0]0-[1]1-[1]1-[2]2-[3]3-[5]5-[7]7-[11]11-[17]17-[25]25-[38]38-[57]57-[86]86-[129]129-[194]194-[255]255-[255]255" --green-gamma-table "[0]0-[1]1-[1]1-[2]2-[3]3-[5]5-[7]7-[11]11-[17]17-[25]25-[38]38-[57]57-[86]86-[129]129-[194]194-[255]255-[255]255" --blue-gamma-table "[0]0-[1]1-[1]1-[2]2-[3]3-[5]5-[7]7-[11]11-[17]17-[25]25-[38]38-[57]57-[86]86-[129]129-[194]194-[255]255-[255]255" > /home/erippeto/lib/Apps/d55/align/Page_scan.ppm scanimage: option --red-gamma-table: index 0 out of range [0..-1] Thanks, -- Ed Rippetoe Lexmark International
