RE: [Geotools-gt2-users] using the GeoTiff Reader

[Patrick W. <pa...@wa...>]

Hello,

I have been using the WorldImageReader with the following code:


   DefaultMapContext mpCntx = new DefaultMapContext();

   //  I am not sure why but a PlanarImage object must be created first

   PlanarImage img = (PlanarImage)JAI.create("fileload","test");

   WorldImageReader wir = new WorldImageReader(new File(filepathstring));
      try{
        GridCoverage2D gc = (GridCoverage2D) wir.read(null);
        StyleBuilder sbImg = new StyleBuilder();
        RasterSymbolizer rs = sbImg.createRasterSymbolizer();
        Style rasterStyle = sbImg.createStyle(rs);
        mpCntx.addLayer(gc, rasterStyle);
      }catch(Exception ex){System.out.println("MpCntxBuilder.mapLoadImage " + ex.getMessage());}
