Hi!
|
|
<BR>
|
|
<P>Ok. Then try this: in line 3958
|
|
<BR>
|
|
<P>change
|
|
<BR>
|
|
<P> dev->bdiff = dev->rdiff + (...);
|
|
<BR>
|
|
dev->gdiff = dev->rdiff + (...);
|
|
<BR>
|
|
<P>to
|
|
<BR>
|
|
<P> dev->bdiff = dev->rdiff;
|
|
<BR>
|
|
dev->gdiff = dev->rdiff;
|
|
<BR>
|
|
<P>and set both values to one. This should result in no line distance
|
|
<BR>
|
|
correction. To fix the resolution is another topic. If you don't mind,
|
|
<BR>
|
|
we'll first try to get the colors working :)

<P><EM>> Tried it out, problem got worse. Set them both to zero, got floating point errors
|
|
</EM><BR>
|
|
<EM>> when scanning. Set them to 1 and got better reults then with the original
|
|
</EM><BR>
|
|
<EM>> setting, but still not quite right. I think zero would be better. Also noticed
|
|
</EM><BR>
|
|
<EM>> that colors aren't correct. I was scanning sheet of white paper with blue
|
|
</EM><BR>
|
|
<EM>> writing. Paper came out white, but the ink looked more like a brownish black.
|
|
</EM><BR>
|
|
<EM>> Maybe that is because of the offset. How can I fix the resolution? The scanner
|
|
</EM><BR>
|
|
<EM>> runs only have of the length of the page, and scans only about a quarter of the
|
|
</EM><BR>
|
|
<EM>> width. I think this is because of the higher resolution of this scanner. It has
|
|
</EM><BR>
|
|
<EM>> an optical resolution of 600x1200 dpi.
