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
