/**
 * @class   vtkTIFFWriter
 * @brief   write out image data as a TIFF file
 *
 * vtkTIFFWriter writes image data as a TIFF data file. Data can be written
 * uncompressed or compressed. Several forms of compression are supported
 * including packed bits, JPEG, deflation, and LZW. (Note: LZW compression
 * is currently under patent in the US and is disabled until the patent
 * expires. However, the mechanism for supporting this compression is available
 * for those with a valid license or to whom the patent does not apply.)
