6    * This example converts a PDF to a multi-page TIFF, using the
7    * PDF Viewer extension. 
8    * 
9    * Usage is:
10   *
11   *   java PDFtoTIFF [--dpi nnn] [--bw | --gray | --rgb | --rgba | --cmyk] <nnn.pdf>
12   *
13   * where dpi is the DPI of the final image (defaults to 72) and
14   * bw, gray and rgb cause the image to be created as 2-color
15   * black and white, grayscale or RGB (the default) respectively.
16   *
17   * The output filename is of the form "nnn.tif"
18   *
19   * Note converting to Black and White or GrayScale will take longer,
20   * as Java has to recolor the image as well.
21   *
22   * @since 2.5
