Hi Maxim,<br>
I have tried your changes and they look good, although I have not
looked at the code in detail.<br>
If you would like to submit the changes for inclusion into xsane
upstream, please create a cross-fork merge request, which I believe
to be the proper process.<br>
<br>
I've not done one of these before, so it will be an interesting
experience. :)<br>
<br>
Cheers,<br>
Ralph<br>

<p>Hello everybody!</p>
<p>Some time ago I tried to scan a big archive of old camera rolls
with xSane and found problems:</p>
<ol>
<li>Its 'scan area selection' was wrong, it got a shift if the
Preview was zoomed in.</li>
<li>'Zoom to point' and 'Zoom out' worked in a weird manner, it
lost the center point.<br>
</li>
<li>The image was tied to the top-left corner that is pretty
unusual nowadays.</li>
<li>Zoom did not react to the size of window.<br>
</li>
</ol>
<p>It would make scanning frustrating, so I decided to make a
custom version of xSane.</p>
<p>Major changes, Preview window:<br>
</p>
<p>* xsane-preview.h/c : geometry calculations of Preview window
revised, clarified and simplified.<br>
* Preview image reacts on the window size: the same part of
image is visible after resizing.<br>
* 'Fit to screen' stated as a separate mode that allows to see
the entire image regardless of the window size.<br>
* Zoom In/Zoom Out work as it supposed to do.</p>
<p>Minor changes:</p>
<p>* aclocal.m4 removed, it is a generated file.<br>
* configure, configure.in fixed, it could not detect SANE
installed.<br>
* New button 'Half frame for 135 type camera roll' added, it
creates a selection bix of the mentioned size that can be
dragged to shots on the camera roll.<br>
* New xsane_list_all_scanner_parameters() function in xSane that
dumps everything found in the results of sane_control_option().</p>
<p>I am not sure if my changes to configure files are good enough,
but the original files did not work at all.</p>
<p>Also, xSane is tested only with my computer & my scanner
(Cannonscan 9000F).</p>
