ps2fax - image PostScript® for facsimile transmission

SYNOPSIS

/var/spool/fax/bin/ps2fax [ -12 ] [ -o output ] [ -w pagewidth ] [ -l pagelength ] [ -r vertres ] [ files... ]

DESCRIPTION

Ps2fax takes PostScript input and generates a TIFF Class F image file suitable for facsimile transmission. It is usually invoked by a facsimile server process. On IRIX version 4.0-based systems, this application is based on Adobe's Display PostScript software.

Input files containing PostScript may be specified on the command line. If none are given, then ps2fax will read from standard input.

By default, ps2fax will generate a 98 line/inch output document whose page width is 1728 pixels and page length is 297 mm (a standard A4 page at low resolution). Horizontal resolution is always 204 dpi. The -r option can be used to specifiy an alternate vertical resolution (typically 196 lpi for fine resolution). The page width and page length can be specified with the -w and -l options, respectively. Note that page width is specified in pixels, while page length is specified in millimeters.

The -o option is used to specify the name of the output file. If no filename is given, the output is placed in a file named ps.fax.

By default, output is compressed using the standard Group 3 1D encoding scheme, with EOL codes padded to byte boundaries. If the -2 option is specified, output is encoded with the optional Group 3 2D encoding scheme (EOL codes are still padded to byte boundaries). 1D encoding can also be explicitly specified with the -1 option.

RUNTIME ENVIRONMENT

Before user-supplied PostScript is passed to the PostScript interpreter, a limited number of operators are defined. These operators are operators commonly found in a LaserWriter printer and (sometimes) generated by Macintosh-based applications.

The default environment includes support for the following Adobe Type 1 fonts:

AvantGarde-Book	Helvetica-Narrow-Oblique
AvantGarde-BookOblique	Lithos-Bold
AvantGarde-Demi	NewCenturySchlbk-Bold
AvantGarde-DemiOblique	NewCenturySchlbk-BoldItalic
Bookman-Demi	NewCenturySchlbk-Italic
Bookman-DemiItalic	NewCenturySchlbk-Roman
Bookman-Light	Palatino-Bold
Bookman-LightItalic	Palatino-BoldItalic
Courier	Palatino-Italic
Courier-Bold	Palatino-Roman
Courier-BoldOblique	StoneSerif
Courier-Oblique	Symbol
Helvetica	Tekton
Helvetica-Bold	Times-Bold
Helvetica-BoldOblique	Times-BoldItalic
Helvetica-Oblique	Times-Italic
Helvetica-Narrow	Times-Roman
Helvetica-Narrow-Bold	ZapfChancery-MediumItalic
Helvetica-Narrow-BoldOblique	ZapfDingbats

Note that this is the same set of fonts supported by the DPS extension to the X server.
