Dear Simone,
thank you very much for the simplified sld and the code. Indeed, there
is progress: the change to the last two lines :
rsh.visit(rs);
((GridCoverage2D)rsh.getOutput()).show();
helped. I guess this is the way it should be included in the tutorial as
well. However, not all is good
Ciao Martin,
what you are seeing is just a warning, the only consequence (or at
least the one you should care of) is that JAI will work in pure java
mode, withou native acceleration.
About the shaded gray, can you be more specific?
Simone.
Hi Simone,
thanks for the exaplanation. I would still like to use the acceleration
provided through the mlib wrapper, is there a way to use it through maven?
Regarding the colors: all the cells are displayed in shades of grey,
despite my styling that contains something like:
ColorMapEntry
Simone,
thanks so much for your help, here it is;
code snippet:
somewhere in my processing chain, I set up cell values as follows:
WritableRaster myraster
myraster.setSample(xx, yy, 0, 6);
and then:
GridCoverageFactory gcFactory = new GridCoverageFactory();
GridCoverage2D gchor =
Ciao Martin,
two things:
1 can you try to remove the channelselection elemt entirely?
2 can you wrote as geotiff and then send over one of your raster so
that I can use it?
Simone.

Ciao Martin,
I use the sample code here:

with this style:

Simone,
thanks so much, problem resolved. I had the color ramp commented out,
probably during some playing around. All works now, thanks a lot!
Cheers

Dear all,
I am creating a gridcoverage2D (and consequently a geotiff, based on
processing of a source geotiff DEM), and I want to quickly visualize the
results of the analysis. Instead of opening it in some GIS, I would like
to assign a color model to the result.and display it through the
Ciao Martin,
a way to achieve that is by using the RasterSymbolizer (2.5.0 and
successive releases).
See http://docs.codehaus.org/display/GEOTOOLS/Raster+Symbolizer+support
for more information.

Hi Simone,
that looks good. HOw do you create the Stle factroy (is is not in the
code...and I did not do any styling before...). Could you maybe also
upload the imports in that tutorial, please?
Cheers

Hi Simone,
I have solved the Style factory problem as follows:
SLDParser stylereader = new SLDParser(new StyleFactoryImpl() ,

I have imported the UserLayer, Style and all following classess from

Ciao Martin,
please, send over the SLD file you are using.

I used the one in your example, with changed values that are to be

Ciao Martin,
I copied and pasted (with few modifications) your stile inside the
renderer tests and it worked. I am attaching it to this email.
The code used is as follows:
RasterSymbolizerHelper rsh = new RasterSymbolizerHelper(gc,
null);
final UserLayer nl =
