[Geotools-gt2-users] Reprojecting Rasters using Lite - need a code review

[Richard G. <rg...@re...>]

Greetings all.

The following code doesn't seem to work. I have been staring at it too 
long to notice any issues. Anyone notice anything out of place?

Thanks,

Richard

    protected void paintImage( BufferedImage image, Graphics2D 
destination, int width, int height,
            Envelope incomingBBox ) {

            CRSService service = new CRSService();
            org.geotools.cs.CoordinateSystem cs = 
service.cs(getContext().getViewportModel()
                    .getCRS());

            org.geotools.pt.Envelope gtBbox = new 
org.geotools.pt.Envelope(new double[]{
                    incomingBBox.getMinX(), incomingBBox.getMinY()}, new 
double[]{
                    incomingBBox.getMaxX(), incomingBBox.getMaxY()});

            GridCoverage grid = new GridCoverage(
                    "BasicWMSRenderer temporary reprojecting 
GridCoverage", image, cs, gtBbox);

            StyleBuilder sb = new StyleBuilder();
            ColorMap cm = sb.createColorMap(new double[]{1000, 1200, 
1400, 1600, 2000},
                    new Color[]{new Color(0, 255, 0), new Color(255, 
255, 0),

                            new Color(255, 255, 255)}, ColorMap.TYPE_RAMP);
            RasterSymbolizer rsDem = sb.createRasterSymbolizer(cm, 1);
            Style style = sb.createStyle(rsDem);

            MapContext mapContext = new DefaultMapContext();
            mapContext.addLayer(grid, style);

            LiteRenderer2 lite = new LiteRenderer2(mapContext);

            Rectangle paintArea = new Rectangle(width, height);

            AffineTransform transform = 
lite.worldToScreenTransform(incomingBBox, paintArea);
            transform.concatenate(this.affineTransform);

            lite.paint(destination, paintArea, transform);

    }
