problem crop scanned image

[marcial]

Hello! I have a problem. I must crop a scaned image in java but when I show the image in the screen, the scanner don’t crop it and shows the whole image.

I saw a little the twain specification but I don’t find the solution. It seems it could be something like this:

s.setCapability(s.ICAP_UNDEFINEDIMAGESIZE, new ValueContainerOneValue(new ItemTypeInteger(1)));
s.setAutomaticBorderDetection(true);

My scanner is CanonScan 8800F

Thanks!!
