Description
I have a raster layer which operates through GDAL. The classification shows up in the map image, but the legend produces an empty image. I also tested this with legend.exe same result. The classification is on [pixel]. Added Frank to the cc as he might know something about this. This is my MAP file: MAP # NAME is the WMS root layer NAME "Basispakket" STATUS ON EXTENT 50000 400000 350000 650000 SIZE 860 590 SHAPEPATH "D:/data/geopakhuis/" IMAGETYPE PNG IMAGECOLOR 255 255 255 FONTSET "C:/ms4w/apps/chameleon/etc/fonts.txt" UNITS METERS WEB IMAGEPATH "/ms4w/tmp/ms_tmp/" IMAGEURL "/ms_tmp/" METADATA "WMS_TITLE" "Basispakket WMS" "WMS_ABSTRACT" "Basispakket WMS via UMN Mapserver" "WMS_ACCESSCONSTRAINTS" "none" "WMS_SRS" "EPSG:28992" "WFS_TITLE" "Basispakket WFS via UMN Mapserver" "WFS_SRS" "EPSG:28992" "OWS_SCHEMAS_LOCATION" "http://schemas.opengis.net" "WFS_ONLINERESOURCE" "http://www.vz.geodan.nl:1111/cgi-bin/mapserv.exe? map=/ms4w/apps/general/map/test.map&" END END PROJECTION "init=epsg:28992" END LEGEND IMAGECOLOR 255 255 255 KEYSIZE 18 12 KEYSPACING 5 5 LABEL SIZE 8 TYPE truetype FONT sans BUFFER 0 COLOR 0 0 0 FORCE FALSE MINDISTANCE -1 MINFEATURESIZE -1 OFFSET 0 0 PARTIALS TRUE END POSITION LL STATUS ON END OUTPUTFORMAT NAME "png" MIMETYPE "image/png" DRIVER "GD/PNG" EXTENSION "png" IMAGEMODE PC256 TRANSPARENT FALSE END ########################################## # 4.

Frank, Sorry, this is such a stupid mistake, it works now. I copied the classes from your Raster howto tutorial and did not change them. Bart
