Thanks for sharing that Mario. We may be able to use such a tool and
I'll give it a test run when I get a chance. If I spot something that
cures your problems I'll post it.

If you like this one, perhaps you would be interested as well in other tools and/or modifications to
existing modules. For example, I have added a "Gamma Lock" feature in the Raster Source tab of the
gvrasterpropdlg.py to adjust the min and max values separately using the Red slider, without
destroying the color balance. I also made a few changes to the gvviewwindow.py such as:
- the Goto dialog now works with lon-lat
- the first image in a view is opened at 1:1 resolution by default
- added a "Multiple Open" that uses filedlg.py
- added a "Open RGB" that combines 3 bands into an RGB VRT dataset (also uses filedlg.py)
- added functions to enable the use of root and square enhancements (they were forgotten?)
In order to enable some of these features, the XML config files would need to be modified.
Finally, I am still putting the finishing touch on a "Finder" tool that will search for a location
in user-specified feature databases (dbf or others) and display a list of Landsat scenes containing
that location. From this list, the user could then load the desired scene which would open centered
on the selected location. The tool is not fully configurable yet (some of the parameters are set
directly in the code... not good!) but I'm working on it...
Note that the changes made to existing modules only better suit my needs. So I share them with
others who may have the same needs. I don't pretend that this how the OpenEV software should work...
in fact, I credit the OpenEV team to make it easy for a rookie like me :)
Thank you for your interest.
