Hi all,
|
||
|
|
<BR>
|
||
|
|
I don't know whether it's a well known problem, or whether it
|
||
|
|
<BR>
|
||
|
|
only occurs with the backend I'm using, or whether
|
||
|
|
<BR>
|
||
|
|
I should report it directly to the maintainers,but since the
|
||
|
|
<BR>
|
||
|
|
guys monitor this list anyway...
|
||
|
|
<BR>
|
||
|
|
<P>I first noticed this when I tried to implement my own frontend.
|
||
|
|
<BR>
|
||
|
|
Sometimes the image size seemed to be wrong.
|
||
|
|
<BR>
|
||
|
|
Therfore I made a short test with xscanimage1.0.2 and xsane0.59...
|
||
|
|
<BR>
|
||
|
|
same problem :-(
|
||
|
|
<BR>
|
||
|
|
<P>At least the backend I'm using (plustek V0.36-18)doesn't allow you
|
||
|
|
<BR>
|
||
|
|
to set a tlx/tly value that's bigger than the brx/bry value, even
|
||
|
|
<BR>
|
||
|
|
if this is only an intermediate state.
|
||
|
|
<BR>
|
||
|
|
<P>That's very annoying when you want to adjust the scansize in the
|
||
|
|
<BR>
|
||
|
|
preview window in xsane/xscanimage.
|
||
|
|
<BR>
|
||
|
|
<P>Let's say you selected a scanarea from 0,0 to 50,50 mm. Then you decide
|
||
|
|
<BR>
|
||
|
|
that you like to scan from 100,0 to 150,50 mm. But xsane/xscanimage
|
||
|
|
<BR>
|
||
|
|
resizes the rectangle to 50,0 /150,50 mm, because it tries to set the tlx value
|
||
|
|
<BR>
|
||
|
|
to 100 while the brx value is still 50, and that forces the backend to set the
|
||
|
|
<BR>
|
||
|
|
tlx value back to 50. (errm, is there someone who knows what I'm trying to
|
||
|
|
<BR>
|
||
|
|
say?).
|
||
|
|
<BR>
|
||
|
|
The result is, that I have to choose the scan area twice (most of the time)
|
||
|
|
<BR>
|
||
|
|
to finally get what I want :-(
|
||
|
|
<BR>
|
||
|
|
<P>Just if this might be of interest for someone...
|
||
|
|
<BR>
|
||
|
|
<P>bb Michael
|
||
|
|
<BR>
|
||
|
|
<P>BTW One can work around this by setting the scan area to it's
|
||
|
|
<BR>
|
||
|
|
maximum size before trying to set the user values.
|
||
|
|
<BR>
|
||
|
|
|
||
|
|
<BR>
|
||
|
|
<P><PRE>
