Hello everybody!
Some time ago I tried to scan a big archive of old camera rolls with
xSane and found problems:
1. Its 'scan area selection' was wrong, it got a shift if the Preview
was zoomed in.
2. 'Zoom to point' and 'Zoom out' worked in a weird manner, it lost
the center point.
3. The image was tied to the top-left corner that is pretty unusual
nowadays.
4. Zoom did not react to the size of window.
It would make scanning frustrating, so I decided to make a custom
version of xSane.
Major changes, Preview window:
* xsane-preview.h/c : geometry calculations of Preview window revised,
clarified and simplified.
* Preview image reacts on the window size: the same part of image is
visible after resizing.
* 'Fit to screen' stated as a separate mode that allows to see the
entire image regardless of the window size.
* Zoom In/Zoom Out work as it supposed to do.
Hah, yes! I also find the preview window zoom options annoying and I had
some plans to look at this.
I will certainly look at your changes!
I also intend to add mouse scrolling for zoom which is pretty standard
fare these days.
Minor changes:
* aclocal.m4 removed, it is a generated file.
* configure, configure.in fixed, it could not detect SANE installed.
This change is in progress. Yes, configure etc should be generated.
* 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.
* New xsane_list_all_scanner_parameters() function in xSane that dumps
everything found in the results of sane_control_option().
I am not sure if my changes to configure files are good enough, but
the original files did not work at all.
No worries! Patches and enhancements always welcome.
Cheers,
Ralph
