WritableRaster til bmp-fil

Jeg fandt selv ud af det :-))

hvis nogen er intereserede gemmer denne funktion et WriteableRaster (8bit gråtoner) som en tif (gad ikke bmp alligevel)

public void saveRaster(WritableRaster raster) throws java.io.FileNotFoundException {
        SampleModel sampleModel = RasterFactory.createBandedSampleModel(DataBuffer.TYPE_BYTE, raster.getWidth(), raster.getHeight(), 1);

        ColorModel col = PlanarImage.createColorModel(sampleModel);
        BufferedImage bufImage = new BufferedImage(col, raster, false, null);
       
        String outputFile = \"c:/am23/out.tif\";
        // Load the input image.
        //RenderedOp src = JAI.create(\"fileload\", inputFile);

        // Encode the file as a BMP image.
        FileOutputStream stream = new FileOutputStream(outputFile);
        JAI.create(\"encode\", bufImage, stream, \"TIFF\", null);

        // Store the image in the BMP format.
        JAI.create(\"filestore\", bufImage, outputFile, \"TIFF\", null);

    }
