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
