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());}
Pat
