Hi all
I'm trying to to write a double[][] array to a IPixelBlock3 instance using Java. Here is an abstract of my source.
Using this code, I'm getting the following exception:
If I change the double[][] to a int[][] and using the PT_UCHAR (8-bit integer) it works.
Does someone has any idea how to store double precision values / points?
Thanks a lot
I'm trying to to write a double[][] array to a IPixelBlock3 instance using Java. Here is an abstract of my source.
Code:
IRasterWorkspace2 workspace = new IRasterWorkspace2Proxy(new RasterWorkspaceFactory().openFromFile(folder, 0));
try {
double[][] data = cache.get(key);
int height = data[0].length;
int width = data.length;
IUnknownCoordinateSystem sr = new UnknownCoordinateSystem();
IPoint origin = new Point();
origin.putCoords(12.5, 12.5);
IRasterDataset rasterDataset = workspace.createRasterDataset(filename, "GRID",
origin, width, height, 25, 25, 1, rstPixelType.PT_DOUBLE, sr,
true);
IRasterBandCollection rasterBands = new IRasterBandCollectionProxy(rasterDataset);
IRasterBand rasterBand;
IRasterProps rasterProps;
rasterBand = rasterBands.item(0);
rasterProps = new IRasterPropsProxy(rasterBand);
rasterProps.setNoDataValue(255);
IRaster raster = rasterDataset.createDefaultRaster();
IPnt blocksize = new Pnt();
blocksize.setCoords(width, height);
IPixelBlock3 pixelblock = new IPixelBlock3Proxy(raster.createPixelBlock
(blocksize));
pixelblock.setPixelData(0, data);
IPnt upperLeft = new Pnt();
upperLeft.setCoords(0, 0);
IRasterEdit rasterEdit = new IRasterEditProxy(raster);
rasterEdit.write(upperLeft, new IPixelBlockProxy(pixelblock));
Cleaner.release(rasterEdit);
} catch (UnknownHostException e) {
throw new IOException(e.getMessage());
} catch (IOException e) {
throw e;
