Hello! I just have placed a new version of the development code for GT68xx-based scanners at:
http://www.mivlgu.murom.ru/~vsu/gt68xx/ In the version 0.0.6, AFE offset/gain autoconfiguration was implemented, based on the code from David Stevenson <[email protected]>. Currently it was tested on the Mustek BearPaw 2400 TA, seems to work. It is possible that the GT6801 support was broken by this; changing the first #if 0 to #if 1 in gt68xx_scanner_calibrate() (gt68xx_high.c) should restore the old behavior (without the autoconfiguration). A note about the dark images: I have noticed that the default settings of the Windows driver have gamma=1.6. In my program this gamma correction is not implemented; however, if you do it in GIMP or ImageMagick, the result seems to be close to the Windows-scanned images. -- Sergey Vlasov
