Running Ubuntu 14.04 with GeoServer 2.7.2. I've got gdal-bin 1.10.1 libgdal1h 1.10.1 and python-gdal 1.10.1 installed from the default repository.
I'm using gdal_retile.py to create an image pyramid which is then hosted on geoserver. I'd prefer to use PNG but it doesn't appear to be supported.
So far I've found:
-co "COMPRESS=JPEG" -co "COMPRESS=LZW"
gdal_retile.py -v -r bilinear -levels 7 -ps 2048 2048 -co "TILED=YES" -co "COMPRESS=LZW" -targetDir ./kenai translated/*.TIF
What compression algorithms or image formats are supported in the gdal_retile.py "COMPRESS=" argument?
