xlator_call - shell script to invoke PostScript translators
Syntax
xlator_call datatype orientation pagesize width length indent
Description
This Bourne shell script can be called by the line printer daemon to invoke the appropriate translator to convert each data type to Post-
Script. The data type passed by may be specified by using the command with the -Ddatatype option, or by using the Da=datatype capability
in the file.
For a file in a data syntax to be translated to PostScript, the script must contain a case branch which recognizes the data type string and
calls a suitable filter. The supplied recognizes the ANSI, ASCII, ReGIS and Tektronix 4014 data types.
Arguments
datatype
The valid data types are: or any other for which a translator has been installed.
orientation
The valid orientations are: portrait or landscape.
pagesize
The valid page sizes are: or
width
The width (in characters) of the page.
length
The length (in lines) of the page.
indent
The amount (in spaces) the output is to be indented.
All the valid arguments are described in detail by the reference page.
Examples
An example shell script is shown below:
case $datatype in
ansi)
exec ansi_ps -F $pagesize -O $orientation -e "$@";;
ascii)
echo "( 04) cvn {} def"
exec ln03rof -w$width -l$length -i$indent;;
postscript)
exec cat;;
tek4014)
exec tek4014_ps -F $pagesize -O $orientation;;
regis)
exec regis_ps -F $pagesize -O $orientation;;
*)
echo "$0: Translator for data type $datatype not installed" >&2
