Hi,
I have a simple test to interpolate no data values for a GridCoverage using
the example in the page.
http://docs.geotools.org/latest/userguide/library/coverage/grid.html
javax.media.jai.Interpolation interp =
Interpolation.getInstance(Interpolation.INTERP_BILINEAR);
GridCoverage2D covinterpol = (GridCoverage2D)
Operations.DEFAULT.interpolate(scicov, interp);
RenderedImage ri = covinterpol.getRenderedImage();
But my result coverage is always equals to the input. I'm missing something
or doing something wrong?
GridCoverageFactory gcf = new GridCoverageFactory();
Map<String, Object> properties = new HashMap<>();
properties.put(NoDataContainer.GC_NODATA, new NoDataContainer(-9999));
GridCoverage2D inputCov = gcf.create("INPUT", renderedImage,
gridCoverage2D.getEnvelope(), null, null, properties);
javax.media.jai.Interpolation interp =
Interpolation.getInstance(Interpolation.INTERP_NEAREST);
GridCoverage2D outputCoverage = (GridCoverage2D)
Operations.DEFAULT.interpolate(inputCov, interp);
RenderedImage ri = outputCoverage.getRenderedImage();
GridCoverage2D newCov = gcf.create("NEW", ri,
outputCoverage.getEnvelope(), null, null, properties);
Thank you
