Hi Gerhard,
I have been playing around with the scanner a bit more and the following
things have come to light:
* Colour images at all resolutions misregister red/green/blue images
* Gray scale images only work up to 150dpi - beyond that, and sometimes on
this resolution for large images, images are "banded" with non-contiguous
bands of image; sometimes with horizontal offset- the higher the resolution
(300dpi max) the worse the banding.
* Trying to scan an image of any size or resolution on "Colour32" mode gives a
"scanner not started - Out of Memory" error.
Pieter
Sample debug output (initialisation and a 300dpi color scan which gives banded
misregistered image) (do you want me to mail it to you? - 66k png)
