TIFF - Need to set Whiteiszero (JAI)

Question

Hi,
I manipulate images, if it's a RGB picture, I change it to a gray scale and I change it again to a 1-bit pictures (bilevel). When I save this picture to a tiff, JAI set it's Photometric param to Blackiszero but I want to encode my picture with Whiteiszero....
My compagny use a old tiff viewer, so when I open my encoded file, all pixels are inverted, I really need to set "white is zero" to fix that problem...
I use this code to convert to a 1-bit
PlanarImage dst =
JAI.create("binarize", src, new Double(200));
And I encode my TIFF with this code:
int TIFF_PHOTOMETRIC = 262;
TIFFEncodeParam params = new TIFFEncodeParam();
params.setCompression(TIFFEncodeParam.COMPRESSION_GROUP4);
TIFFField[] extras = new TIFFField[4];
extras[0] = new TIFFField(TIFF_PHOTOMETRIC, TIFFField.TIFF_SHORT, 1, (Object) new char[] {0});
extras[1] = new TIFFField(TIFF_XRESOLUTION, TIFFField.TIFF_RATIONAL, 1, (Object)new long[][] {{(long)200, (long)1},{(long)0 ,(long)0}});
extras[2] = new TIFFField(TIFF_YRESOLUTION, TIFFField.TIFF_RATIONAL, 1, (Object)new long[][] {{(long)200, (long)1},{(long)0 ,(long)0}});
extras[3] = new TIFFField(TIFF_RESOLUTION_UNIT, TIFFField.TIFF_SHORT, 1, (Object) new char[] {2});
params.setExtraFields(extras);
ImageEncoder encoder = ImageCodec.createImageEncoder("TIFF", out, params);
encoder.encode(image);

I found the solutions to force JAI to encode with the tag PhotometricInterpretation set to white is zero.

You need a binarized image.
// Invert the colormodel
byte[] map = new byte[] {(byte)( 255),(byte)(0)};
IndexColorModel colorModel = new IndexColorModel(1, 2, map, map, map);
// Create a bufferedimage with the good colormodel
BufferedImage bi = new BufferedImage(newImg.getWidth(), newImg.getHeight(), BufferedImage.TYPE_BYTE_BINARY, colorModel);
bi.setData(newImg.getAsBufferedImage().getData());
// Invert the image
DataBufferByte dataBufferByte = (DataBufferByte)bi.getRaster().getDataBuffer();
byte[] buffer = dataBufferByte.getData();
for (int lll = 0; lll < buffer.length; lll++) {
buffer[lll] = (byte)(~buffer[lll]);
PlanarImage = PlanarImage.wrapRenderedImage(bi);
