Indeed, I don't believe that image compositing based on alpha band is possible with VRT. You could have some success if you used a RGB image with NODATA instead. Otherwise to composite RGB images with RGBA images, you have to use gdalwarp and produce a "normal" output image (like GeoTIFF) > > > > _______________________________________________ > gdal-dev mailing list > gdal-dev@lists.osgeo.org > http://lists.osgeo.org/mailman/listinfo/gdal-dev _______________________________________________ gdal-dev mailing list gdal-dev@lists.osgeo.org http://lists.osgeo.org/mailman/listinfo/gdal-dev
