Dear listmembers, maybe I am on the wrong list because my problem might be application - specific, however.
I have set up a HP 7400C scanner, supported by the avision backend, it is detected and working. So far, so good. Now, if I scan a black and white printed text with xsane and adjust all parameters to default, 300dpi, Gray, contrast and brightness set to 0, (=100%), the resutls are nice quality scans, black is black, background is white. In contrast, attempting to do the very same with scanimage, calling: scanimage --mode Gray --contrast 0 --brightness 0 --resolution 300 > outfile the resulting picture in "outfile" (same printed text as above) is very bright, grey rather than black. Modifying brightness is making the result worse, modifying contrast as well. I cannot achieve the same result as with xsane - what makes me wonder as I had had expected to work the same way .... Any ideas / hints for me? I could provide resulting scans for explanation, however, I think I cannot upload anything. Regards, many thanks for your efforts Dieter Jurzitza -- ----------------------------------------------------------- Dr.-Ing.
