Hi Andrea, okay here is a little explanation. The VectorToRaster process was only a test of useability of using WPS-Transformation in raster symbolizer. My task is a distribution map or heatmap of point-vector-based data. So I found this blog http://geo-solutions.blogspot.com/2011/01/developers-corner-have-your-sld.html and thought this will be an good solution. Now I will produce an panchromatic image in my own geoserver wps and colorize it with SLD raster symbolization. Okay it would be possible produce RGB(A) image in wps a well, but so I'm flexible in SLD with the presentation. Now I can produce my heatmap in all WMS output formats that perform raster images.
I tested the sld with both version. 2.1.3 and nightly build from yesterday. :-) In nightly build version it works now.
