Hello,
I am working on a really "simple" task, but I do not make any progress with it.
In have got a GridCoverage2D which I want to interpolate. I am using some
sample code from the GeoTools documentation:
javax.media.jai.Interpolation interp =
Interpolation.getInstance(Interpolation.INTERP_BILINEAR);
GridCoverage2D covinterpol = (GridCoverage2D)
Operations.DEFAULT.interpolate(scicov, interp);
RenderedImage ri = covinterpol.getRenderedImage();
My problem is that the resulting RenderedImage is equal to the input image of
the GridCoverage2D scicov. Nothing changes. What am I doing wrong?
My own try is not working, too:
Final Interpolation[] interpolation = new Interpolation[] {
Interpolation.getInstance(Interpolation.INTERP_BICUBIC),
Interpolation.getInstance(Interpolation.INTERP_BICUBIC_2),
Interpolation.getInstance(Interpolation.INTERP_BILINEAR),
Interpolation.getInstance(Interpolation.INTERP_NEAREST) };
Final ParameterValueGroup param = interpolateParams.clone();
param.parameter("Source").setValue(coverage);
param.parameter("Type").setValue(interpolations);
coverage = (GridCoverage2D) interpolateFactory.doOperation(param, hints);
I am grateful for every hint! ;-)
With best regards
Tobias
