Ok so I get an idea of why it did not work :
I replaced :
MapContext context = new DefaultMapContext(DefaultGeographicCRS.WGS84);
context.setTitle(projDir.getName());
with :
MapContext context = new DefaultMapContext(DefaultGeographicCRS.WGS84);
context.setTitle(projDir.getName());
try {
context.setCoordinateReferenceSystem(CRS.decode("epsg:4326"));
} catch (TransformException ex) {
Exceptions.printStackTrace(ex);
} catch (FactoryException ex) {
Exceptions.printStackTrace(ex);
}
Now I dont get anymore my projections problem, but this error :
java.lang.IllegalArgumentException: Le numéro de bande 1 n'est pas valide.

My raster is a one band raster.. but I cant understand the problem... I use
a lot of single band raster (like SRTM) and I get no problem !
I suppose that it can be my way to stylize the raster. Currently, I have a
single band raster with two values : 0 (I want this value to be transparent)
and 200. I have a colormap in my geotiff. So I would like to get it and then
create my
style from this colormap... is this possible ?
Thanks,
Thomas
