I am cross posting this on both geoserver & openlayers lists.. Recently I was enquiring if any of you have seen the exception issues with geoserver 1.5.3. I have further problems with 1.5.3, this time with PNG8.
Is the png8 format rendered by geoserver-1.5.3 fully compliant with the PNG specs? Please ignore my lack of knowledge on PNG. Are there any limitations or certain features not being implemented for this png8 format? I am using Openalyers 2.4 on the client side. Everything is fine on firefox. But both IE6 & IE7 have problems with the png8 produced by geoserver. This manifests in couple of ways: 1) Most of the times, the IE gets redirected to some other page when I use png8 format for openlayers wms layer. (If I use png instead of png8, everything is fine). I am hypothesizing that IE is not able to process the geoserver png8 and gets confused. 2) Lot of times with png8, the openlayers lands in OpenLayers.Util.onImageLoadError() handler. Basically IE thinks that there is some problem with image URL; however the IE ends up drawing the WMS content of the png8 tile fine (but the tile soon gets replaced by a pink tile). Looks like IE thinks that there is something wrong with this tile even though it was able to render it fine. The problem does not consistently happen with one particular tile; the same tile on refresh comes out fine. The support for png8 is very very important for IE6 since IE6 can't handle PNG24 transparency. Any body has any ideas? Thanks in advance..
