[Qgis-user] eliminations of "seams" between raster tiles?

This is something that should be addressed with the upcoming raster
transparency branch merge. Cant say when it will be merged yet, but
keep in touch with Peter Ersts about this. Basically what you need is
to use the same histogram stretch for all your tiled rasters.... We
will be making some test builds of the raster branch in the near
future for people to try out Peter and Marcos magic therein....
