This is with the canon backend? I'm asking because I can't find this scanner in the lists. > First the preview window appears taking a long time after clicking the > Acquire Preview button. > Then using preview scan at 1200 dpi, I got the error message box which said > "Failed allocate image memory: memory". The preview shouldn't depend on the dpi value that is set up but uses it's own (lower) dpi. At least that's what should happen. See src/preview.c preview_scan() for details. The error happens in increment_image_y(). Can you find out what's wrong there? Maybe the backend's parameters (e.g. bytes per line) are wrong/too high? Please add a view debug prints. Please also show us the output of "scanimage --help" for this scanner so we can see, how the resolution option looks like. > So, I cannot get the preview image. > At lower than 1200 dpi, an acquirement of preview is OK. > And a real scan is very good, no problem. > > Is this problem in acquirement of preview at 1200 dpi corrected? > > The XSane is no problem with preview scan and real scan at 1200 dpi. > > Is this problem by only CanoscanFB1200S? > Is there the same problem for other scanner? I have never heard about such a problem and it doesn't happen here with Mustek scanners. Bye, Henning
