.. also, the WMS spec has some things to say about combinations of the FORMAT-, BGCOLOR- and TRANSPARENT-parameters, which always seem to surprise me, and I always need to look up when I need it.

Hi, Works for me with Geoserver 2.8 and these requests: Transparent with this gdalinfo report Band 1 Block=768x1 Type=Byte, ColorInterp=Red Mask Flags: PER_DATASET ALPHA Band 2 Block=768x1 Type=Byte, ColorInterp=Green Mask Flags: PER_DATASET ALPHA Band 3 Block=768x1 Type=Byte, ColorInterp=Blue Mask Flags: PER_DATASET ALPHA Band 4 Block=768x1 Type=Byte, ColorInterp=Alpha http://localhost:8080/geoserver/sf/wms?service=WMS&version=1.1.0&request=GetMap&layers=sf:roads&styles=&bbox=589434.8564686741,4914006.337837095,609527.2102150217,4928063.398014731&width=768&height=537&srs=EPSG:26713&format=image/png&transparent=true Non-transparent with gdalinfo report Band 1 Block=768x1 Type=Byte, ColorInterp=Red Band 2 Block=768x1 Type=Byte, ColorInterp=Green Band 3 Block=768x1 Type=Byte, ColorInterp=Blue http://localhost:8080/geoserver/sf/wms?service=WMS&version=1.1.0&request=GetMap&layers=sf:roads&styles=&bbox=589434.8564686741,4914006.337837095,609527.2102150217,4928063.398014731&width=768&height=537&srs=EPSG:26713&format=image/png This setting makes the map transparent from where there are no vector features. I wonder if your problems is that your polygons are covering the labels from the other layer? Then you must change the rendering order. -Jukka Rahkonen- KhunSanAung wrote: Hi All, I'm using WMS Request to get PNG images from GeoServer. I'm fusing two different PNG layers (One for Features & One for Labels) outside of GeoServer. I found that both of my PNG files are not transparent for overlaying each other.
