Servus !<br>
|
|
<p>
|
|
I have just tested the new sane-0.5.2 release and here are my experiences and<br>
|
|
impressions:<br>
|
|
<p>
|
|
The preview still needs a 16 bit color display, it crashes with 256 colors.<br>
|
|
Since the new Beta 4 of StarOffice seems to need eight bit for displaying<br>
|
|
the icons correct I have to switch the colordepth every time.<br>
|
|
The qcam backand doesn`t compile: <br>
|
|
<p>
|
|
gcc -c -I/usr/X11R6/include -g -O2 -D_GNU_SOURCE -Wall -DHAVE_CONFIG_H -I. -I../include -DPATH_SANE_CONFIG_DIR=/usr/local/etc/sane.d -DPATH_SANE_DATA_DIR=/usr/local/share -DV_MAJOR=0 -DV_MINOR=5 -DBACKEND_NAME=qcam -fPIC -DPIC qcam.c<br>

... a.s.o.<br>

Without qcam it compiles.<br>

Color scanning is a little bit funny now. The first pass is ok but then the <br>
|
|
behavior becomes very strange. After the scanner was started about twenty times<br>
|
|
for "receiving red data for 'out.ppm'..." (text of the progress box) I canceled<br>
|
|
this. Cancellation by the provided button didn`t work, so I had to exit xscan.<br>
|
|
Xscan seems to run into an endless loop - You can go drinking coffee and when <br>
|
|
returning the scanner is still working. I try to explain it in detail:<br>
|
|
After the first pass the scanner is changing the filter (or whatever) and then<br>
|
|
the second pass is started. But during the second and third pass it never scans<br>
|
|
the whole specified area. The carriage jerks a little bit forward then it <br>
|
|
returns and changes the filter. After this another will be started... till<br>
|
|
infinity.<br>
|
|
<p>
|
|
Enough from my neverending-scanning story.<br>
