[Qgis-user] Re: RGB composition plugin

[Mauricio de Paulo]

	As a ubuntu user I also saw that problem. At the moment I'm using
GDAL's internals, not gdal_merge. You could say that the previous
version was based on gdal_merge as I read some of it's code to start the
plugin, but the recent upgrade is not really close to gdal_merge.
gdal_merge used the xml editing that I avoided in this version, so I
really implemented using python-gdal library. That's the only
requirement now.
	Hope it works fine. I still don't know how windows and mac users are
going to cope with python-gdal, but I think I saw the package in the
osgeo repository.
	All the best,
	Maurício de Paulo
