[Geotools-gt2-users] Building a coverage from an array of doubles/floats?

[Ian T. <ijt...@gm...>]

Does any one have example code of how I could go about building a
GridCoverage2D from an array of doubles?
Currently I have:

private GridCoverage2D convert(ArrayList<Circle> results) {
        ReferencedEnvelope resBounds = new
ReferencedEnvelope(bounds.getCoordinateReferenceSystem());
        for(Circle c:results) {
            resBounds.expandToInclude(c.getBounds());
        }
        System.out.println(resBounds);
        GridCoverageBuilder builder = new GridCoverageBuilder();
        builder.setEnvelope(bounds);
        builder.setCoordinateReferenceSystem(bounds.getCoordinateReferenceSystem());
        final double scale = 1000.0;
        final int width = (int)(resBounds.getWidth()/scale);
        final int height = (int)(resBounds.getHeight()/scale);
        builder.setImageSize(width, height);
        BufferedImage img = builder.getBufferedImage();
        QuantizeCircle qc = new QuantizeCircle(img);
        qc.setCellsize(scale);
        for(Circle c:results) {
            qc.quantize(c);
        }
        return builder.getGridCoverage2D();
    }

But I'm struggling with the quantize function as the image doesn't
seem to be the size I was expecting, so I thought I'd ask here to see
if there is an easier way to do this?

Thanks

Ian
