[Qgis-user] QGIS Image Clipper Plugin Available

[Bruce, Bob (CON)]

Agustin:
		I did further testing today on Windows. I've found that
this plugin works fine with the QGIS Standalone installers, I tested it
with both the 1.1 and 1.2 installers. Then I downloaded a new version of
QGIS 1.2 OSGEO4W with several libraries selected and the plugin did not
work with that. I've put a posting into the developers list looking for
help.

I'll keep you posted.

Bruce,

Hopefully you'll find help among the developers,
this is really a critical missing utility in QGIS.
