SpecialHost is a utility for the previewer ShowDVI and the
printerdriver DVIprint. It is started in the background additionally
to the drivers and waits for messages from these programs.
It enables the printerdriver and the previewer to display IFF
graphics. To this end it evaluates the
special-strings. It loads
pictures with the help of an IFF library and adjusts their size to
the resolution of the current driver. It can also store the pictures
in a manner that when called again the labour intensive enlargement
or reduction do not have to be done again.
