Hello,
I have some trouble to render my rasters : the raster is very dark, and we
can't see the relief.
I know today, the support is bad for rasters in the renderer, but if I
uunderstood what simboss told me, there is anyway a basic support.
I tried to do this :
Style style = null;
String[] labels = new String[]{"-67890","0","2550"};
double[] quantities = new double[]{-67890,0,2550};
Color[] colors = new Color[]{Color.BLUE, Color.CYAN, Color.GREEN};
int type = ColorMap.TYPE_RAMP;
StyleBuilder sb = new StyleBuilder();
ColorMap cm = sb.createColorMap(labels, quantities, colors, type);
RasterSymbolizer rs = sb.createRasterSymbolizer();//cm, 1
style = sb.createStyle(rs);
MapLayer temp = new
DefaultMapLayer(patchCoverages(directoryContainingGeoTIFF),
rasterStyle()); // patchCoverages() return a MosaicImageReader
temp.setTitle("mosaic test");
context.addLayer(temp);
I think it is really basic, but even this does not work.
Somebody could explain me what exactly we are able to have today for raster
rendering ?
Thanks,
Thomas
