Okay,
I've finally had a moment to sit down and look at this again. I'm using the latest version of ms4w beta, which is based on beta 6. On all of my imagery, tiled or not, using the processing setting of "RESAMPLE=BILINEAR" results in the raster layer not being drawn. There are no error messages, and a map image is created, but the raster layer is not drawn. Using either "RESAMPLE=NEAREST" and "RESAMPLE=AVERAGE" results in the layer being drawn fine. If I switch to using GD for output, then "RESAMPLE=BILINEAR" works as it should, and the raster layer is drawn. Anyone else run into this?

This is my raster layer: LAYER # Aerials_2003 NAME Aerials_2003 GROUP RemoteSensing TILEINDEX "Aerials_2003.shp" TILEITEM "location" STATUS DEFAULT TYPE RASTER PROCESSING "RESAMPLE=BILINEAR" OPACITY 70 MAXSCALEDENOM 75000 DEBUG ON END and this is my output format: OUTPUTFORMAT NAME "AGG_JPEG" DRIVER "AGG/JPEG" MIMETYPE "image/jpeg" IMAGEMODE RGB EXTENSION "jpg" FORMATOPTION QUALITY=80 END Then the raster layer does not draw. There are no errors at all, but no raster layer. If I comment the PROCESSING line out, then the raster layer appears. If I leave the PROCESSING line in, and change the output format to GD/JPEG, then the raster layer appears. The output of shp2img with debug level set to 2 with the PROCESSING line and agg output is: msDrawRasterLayerLow(Aerials_2003): entering. msResampleGDALToMap in effect: cellsize = 1.000000 msDrawGDAL(Aerials_2003): using RAW_WINDOW=6244 2998 914 913 msDrawGDAL(): red,green,blue,alpha bands = 1,0,0,0 msDrawMap(): Layer 0 (Aerials_2003), 0.172s msDrawMap(): Layer 1 (ParcelLines), 0.016s msDrawMap(): Layer 2 (CadastralLabelsParcel), 0.015s msDrawMap(): Layer 6 (Pipes), 0.016s msDrawMap(): Layer 7 (Abandoned_Pipes), 0.015s msDrawMap(): Layer 8 (New_Pipes), 0.000s msDrawMap(): Layer 9 (ForeignPipelines), 0.016s msDrawMap(): Layer 10 (TapStations), 0.016s msDrawMap(): Layer 11 (RegStations), 0.015s msDrawMap(): Layer 12 (Wells), 0.016s msDrawMap(): Layer 13 (Major-Water), 0.016s msDrawMap(): Layer 14 (Minor-Water), 0.015s msDrawMap(): Drawing Label Cache, 0.016s msDrawMap() total time: 0.344s It appears to be resampling the image, but the raster layer doesn't appear. Is this a bug, or am I missing a setting somewhere? Thanks, Rob McCulley
