|
|
<EM>> The preview scans are all done with 50 dpi, so the quality should
|
|
</EM><BR>
|
|
<EM>> be the same. It can only be a rounding problem.

With this change, it works !
|
|
<BR>
|
|
<P>Now, back to the "resize" function.
|
|
<BR>
|
|
Basically it works : I was confused with the previous problem.
|
|
<BR>
|
|
But the "autoselect" button does not work as expected.
|
|
<BR>
|
|
<P>If I place a drawind in the middle of the bed, any size selected, only
|
|
<BR>
|
|
the bottom line is at the right place, the other ones are at the
|
|
<BR>
|
|
top/left/right ends of the format.
|
|
<BR>
|
|
<P>Why is the color set to 25 instead of 55 in xsane-preview.c, line 5505 ?
|
|
<BR>
|
|
(this has no effect for my problem)
|
|
<BR>
