Locale-dependent prolog Files

The purpose of the prolog.ps file is to set up non-generic fonts. Applications use these predefined PostScript font names for printing. The prolog file must define at least the following font names for Desk Set Calendar manager and mp.

• LC_Times-Roman

• LC_Times-Bold

• LC_Helvetica

• LC_Helvetica-Bold

• LC_Courier

• LC_Helvetica-BoldOblique

• LC_Times-Italic

The following example uses these fonts to print the particular local character set specified:

100 100 moveto
/LC_Times-Roman findfont 24 scale font setfont
(Any text string in your locale) show 

The Solaris localization kit provides a sample prolog.ps file for the Japanese environment. Alternatively, this file is found in the /usr/openwin/lib/locale/ja/print/ directory.

The following example shwos how to add or change composite fonts in an existing prolog.ps.

%
(Foo-Fine) makecodeset12 
(Base-Font) makeEUCfont
%

Suppose you want to define a composite font called LC_Base-Font:

LC_Base-Font is a composite font of Foo-Fine and a base font called Base-Font. Foo-Fine is a font that contains the local character set. You do not need any in-depth PostScript knowledge to add or change a font.

The best way to create a prolog.ps File is to study the example version. In the example prolog.ps, two routines need to be written, makecodeset12 and makeEUCfont. Makecodeset12 sets up local font-encoding information. This routine might differ from locale to locale. MakeEUCfont combines the base font and the locale font to form a composite font. The creator of the prolog file should have good knowledge of PostScript in order to write makecodeset12 and makeEUCfont.

prolog.ps file support is kept for backward compatibility only. Do not create a new prolog.ps file for the printing needs of a locale. Use mp.conf instead.

The path for prolog.ps is

/usr/openwin/lib/locale/$LANG/print/prolog.ps
