* optionString ::= ( option )*
* option ::= "comptype=" string
* "quality=" int
* "bpp=" int
* "bps=" int
* "depth=" int

TIFF convertor class.
Supported parameters are
\begin{tabular}{lcl}
{\tt comptype} && string && compression type (see below)\\
{\tt quality} && int && quality parameter (JPEG)\\
{\tt bpp} && int && override number of bits per p (if not set in the tiff)\\
{\tt bps} && int && override number of bits per s (if not set in the tiff)\\
{\tt depth} && int && override number of colors in the mdd\\
\end{tabular}
The compression type defaults to lzw, but it may be one of the
following (but not all types may be supported by the version of
the TIFF library; note also that some compression types are only
valid for specific colour depths):
\begin{tabular}{ll}
{\tt none}\\
{\tt ccittrle}\\
{\tt ccittfax3}\\
{\tt ccittfax4}\\
{\tt lzw}\\
{\tt ojpeg}\\
{\tt jpeg}\\
{\tt next}\\
{\tt ccittrlew}\\
{\tt packbits}\\
{\tt thunderscan}\\
{\tt pixarfilm}\\
{\tt pixarlog}\\
{\tt deflate}\\
{\tt dcs}\\
{\tt jbig}\\
{\tt sgilog} && Not Linux\\
{\tt sgilog24} && Not Linux\\
{\tt it8ctpad} && Not Linux\\
{\tt it8lw} && Not Linux\\
{\tt it8mp} && Not Linux\\
{\tt it8bl} && Not Linux\\
\end{tabular}
