Hello everyone, i noticed some strange behavior today with rasters served through WMS (ImagePyramid layer) stored in EPSG:3765 - HTRS96 Croatia TM but requested with WGS84 on client side. As EPSG:3765 is incorporated into ArcGIS since 10.x version, the only supported SRS for the layer in 9.3 is WGS84. At first I thought it could be an ArcGIS 9.3 issue due to some custom projection/transformation errors or misconfiguration, but the same error happens in QGIS when project is set to EPSG:3765, on the fly reprojection turned on and WMS layer requested with WGS84. When zooming in and out and panning, you can see some shifts in raster data. I created some screenshots here:
http://dracic.tumblr.com/ Images are taken at scales 1:1000 & 1:2500, vector data is in EPSG:3765 I use bilinear interpolation, but changing it to something else in WMS settings doesn't change anything. Also, tried with setting advanced reprojection to false in tomcat config and it doesn't change anything. I turned off native warp acceleration in JAI settings, because I was worried about potential JVM crashes, but to test the issue I turned it on, and the issue was gone. Can anyone explain this behavior? Is it safe to use native warp acceleration?
