[mapserver-users] Again: Some Problems with WMS-GetLegendGraphic using aggand pixmaps

[Schönhammer, Herbert]

Hi list,

I have already described my problem with WMS-GetLegendgraphic and AGG-Library (posted on 2008/05/07 with subject "Some Problems with WMS-GetLegendGraphic using aggand pixmaps").

But i did not get any reply until now. So I made some tests with Mapserver 5.2.0 and i recognized the same problems as posted earlier.

Now i want to publish an example. Using GD as driver for creating the output, i get the correct legend-image:



The definition looks like:

 OUTPUTFORMAT
   NAME png
   DRIVER "GD/PNG"
   MIMETYPE "image/png"
   EXTENSION PNG
   IMAGEMODE RGBA
   TRANSPARENT ON
 END


Only changing the output-driver, I get the following picture:



The definition looks like:

 OUTPUTFORMAT
   MIMETYPE "image/png"
   NAME 'AGG_Q'
   DRIVER AGG/PNG
   EXTENSION PNG
   IMAGEMODE RGBA
   TRANSPARENT ON
 END

The problem using AGG is this:
=======================

If using a pixmap with "KEYIMAGE ...."

   CLASS
     NAME "Topografische Karte 1:50.000"
     KEYIMAGE "/data/raster/topo_karten/tk50_legende.png"
   END

only a part of the raster-image is used for generating the legend (the right side of th picture, the middle of the picture).


Does anybody know, if this a problem of my map-file or this is a mapserver-bug ?

I would be glad, if anybody can examine this persisting problem !

greetings

Herbert Schoenhammer
