It does work for individual layers. Attempted to change PNG Encoding options to Java own encoder, and PNGJ encoder (recommended). This did not turn off the layer transparency. confirmed that bgcolor is respected using format/jpeg The issue is similar to the one found in this link. http://osgeo-org.1560.x6.nabble.com/bgcolor-for-WMS-not-working-td5000129.html |
