Display files containing g3 and/or g4 coded fax pages

viewfax displays one or more fax files in an X11 window. The input files may be either raw, single-page faxes received by a fax modem with a program such as mgetty, or tiff files such as those used by hylafax. The first or only page of “PC-Research”-style DigiFAX files produced by the ghostscript dfaxhigh or dfaxlow drivers can also be displayed.

Input files using any common fax encoding such as group 3 1 and 2 dimensional and group 4 can be displayed.

The fax images are rendered at full resolution and then successively scaled down by a linear factor of 2 prior to display, until they fit on the screen. The display can be controlled interactively using mouse and keyboard commands.
