Hello, The troubles of ArcGridReader to render properly ASCII ArcGrid File come from the way it get the nodata value from the ascii file. I believe that the actual "no data" value (for instance) is never used in the resulting GridCoverage. It would be a good idea to review the code to settle that once for all.
Moreover, the RasterSymblolizerSupport need also an improvement. That class seem knowing nothing about org.geotools.styling.ColorMap. It is using a java.util.Map as ColorMap instead of the one provided in the Style. So The ColorMap in RasterSymbolizer does not affect layers styling just because the StreamingRenderer is using this RasterSymbolizerSupport via GridCoverageRenderer. Best Regards. Côme LINSOUSSI.
