I thought I would start with the "US" sizes even though in Canada we are quite familiar with "European" sizes. ;-)
I do plan to add support for "European" sizes or make the size freely selectable. I've also been toying with integrating my backend with the rts88xx external backend, which has a freely selectable size. >I understand that it's a bit of work to find out how the size is >encoded but usually the scanners use pixels at some fixed resolution >(or similar) to set the window. > > Currently, I use the size to set the window so having a freely selectable range wouldn't be much of a stretch. However, the motion of the scan head is jerky at some sizes so I don't think I have it fully figured out yet. >Bye, > Henning > > > regards, Fred -------------- next part -------------- An HTML attachment was scrubbed...

The only problem I have is with the preview mode: "scanimage --preview=yes" uses a too high y rsolution, i.e., it produces a picture with a correct number of lines, but fills them with top part of the document only. Preview scans from XSane and Kooka hang the scanner. But this might be a problem of my installation: Perhaps I overlooked a file from the previous 1.0.15 backends version. Has somone else observed a similar behaviour? Regards, Ulrich Deiters
