I am not able to output elevation data as 16 Bit PNGs. Is Mapserver not able to to this ? I tried with a current version of Mapserver on Windows and on Linux. I tried WMS and WCS requests - but I always get 8 Bit PNGs back although I have configured 16INT. Other formats like GTiff or Esri Bil work fine with 16Int.Any ideas ? Thanks, kaipi Here is my mapfile: [...] OUTPUTFORMAT NAME 'tif' DRIVER GDAL/GTIFF IMAGEMODE INT16 MIMETYPE "image/tif" END OUTPUTFORMAT NAME 'pngint16' DRIVER GDAL/PNG IMAGEMODE INT16 MIMETYPE "image/pngint16" END
Harry, I suspect the problem is that the PNG driver supposed unsigned 16bit integer while IMAGEMODE INT16 is signed 16bit integers. We really need a FORMATOPTION that will let us force the pixel data type of the generated file even if it is somewhat different from the IMAGEMODE type. Perhaps you could create an enhancement ticket for this and ensure it is assigned to me (userid: warmerdam)? It should be a pretty easy change.
