Hi all,
I'm struggling with the GT resampling operation. My code (to quarter
the pixels) is working so far, i.e. I get a new GridCoverage with
four times the number of pixels. The pixel values are correct except
for the top-most row and the left column, thus from:
1 2 3
4 5 6
7 8 9
I get:
0 0 0 0 0 0
0 1 2 2 3 3
0 4 5 5 6 6
0 4 5 5 6 6
0 7 8 8 9 9
0 7 8 8 9 9
Here is my code:
GridCoverage2D gc = ...
gc.show("Original");
GeneralGridRange newRange = new GeneralGridRange(new int[] {0, 0},
new int[] {15*2, 10*2});
Envelope env = gc.getEnvelope();
GridGeometry2D gridGeo = new GridGeometry2D(newRange, env);
DefaultProcessor processor = new DefaultProcessor(null);
ParameterValueGroup resampleParams = processor.getOperation
("Resample").getParameters();
resampleParams.parameter("Source").setValue(gc);
resampleParams.parameter("CoordinateReferenceSystem").setValue
(gc.getCoordinateReferenceSystem());
resampleParams.parameter("GridGeometry").setValue(gridGeo);
GridCoverage2D newGc = (GridCoverage2D) processor.doOperation
(resampleParams);
newGc.show("Resampled");
I don't have a clue about the problem. Do you?
Christian
