<i>>>>>> On Sat, 3 May 1997 18:48:24 +0200 (MET DST), Andy Thaller <<a href="mailto:Andy.Thaller@Physik.TU-Muenchen.DE">Andy.Thaller@Physik.TU-Muenchen.DE</a>> said:</i><br>

Andy> I'm using xscanimage from sane-0.56 and gtk-libs from<br>
|
|
Andy> gimp-0.99.9 Having seen the screenshots on the sane-homepage I<br>
|
|
Andy> almost immediately missed the dialog for the cusomizable gamma<br>
|
|
Andy> table. Also, I get a curve_new: sorry, the GTK library this program<br>
|
|
Andy> was linked against does not support the curve widget. Please<br>
|
|
Andy> upgrade to the latest available GTK library.<br>
|
|
<p>
|
|
Andy> According to the code, this is because gtk/gtkcurve.h is<br>
|
|
Andy> missing. Gimp-0.99.9 simply doesn't have it. Is there a still<br>
|
|
Andy> newer version of gtk than that coming with gimp-0.99.9 (which<br>
|
|
Andy> came out just recently) or should I link xscanimage against an<br>
|
|
Andy> older version - and which?<br>
|
|
<p>
|
|
In the SANE ftp directory, there is a file called:<br>
|
|
<p>
|
|
gtk+970426-davidm.tar.gz<br>
|
|
<p>
|
|
It contains the gimp-0.99.9 gtk+ with gtkcurve widget (and a few other<br>
|
|
minor fixes).<br>
|
|
<p>
|
|
Andy> I've also got a suggestion for another feature in xscanimage:<br>
|
|
Andy> many scan-programs allow selecting the colormode for the<br>
|
|
Andy> preview independently of that of the scan itself. with<br>
|
|
Andy> three-pass-scanners one would rather scan a quick preview in<br>
|
|
Andy> gra y and do the high-resolution scan in color. In<br>
|
|
Andy> xscanimage, however, you've got to change the colormode before<br>
|
|
Andy> doing the scan. What do you think about providing mode<br>
|
|
Andy> selectors for each preview and scan allowing the user to<br>
|
|
Andy> select independently?<br>
|
|
<p>
|
|
For 1-pass scanners, I kind of prefer to have the preview be in the<br>
|
|
same mode as the actual scan, but, yes, for 3-pass scanners, your<br>
|
|
suggestion makes perfect sense. One possible solution is to have an<br>
|
|
extra option for 3-pass scanners that forces preview scans in<br>
|
|
grayscale mode. The backend can tell wether a scan is in preview mode<br>
|
|
by looking at the value of option "preview" (which isn't implemented<br>
|
|
in the Mustek backend at present). Do you want to add this feature?<br>
