Usage

From source file:image.text.CreateTifAndAnnotate.java

public void createAnnotatedTif(String[] args, OutputStream out) throws Exception {

    byte[] byteArray = new byte[] { -1, 0 };
    ColorModel colorModel = new IndexColorModel(1, 2, byteArray, byteArray, byteArray);

    // -------------------------------------------------------------------        
    Graphics2D g2d = bufImg.createGraphics();
    g2d.setColor(Color.black);/*  w  ww .j  a va2  s.  c  o  m*/

    PlanarImage planarImage = PlanarImage.wrapRenderedImage(bufImg);

    TIFFEncodeParam encodeParam = new TIFFEncodeParam();
    encodeParam.setCompression(TIFFEncodeParam.COMPRESSION_GROUP4);
    encodeParam.setWriteTiled(false); // false means use strips.
    encodeParam.setTileSize(0, 0); // tiling will make the file size much larger. 
    encodeParam.setLittleEndian(true); // create an Intel (II) format image

    String SoftwareVersion[] = new String[] { "TIFF by Joe, " + this.getClass().getName() };
