;; About ps-mule
;; -------------
;;
;; This package is used for ps-print to print multi-byte buffer.
;;
;; See also ps-print.el.
;;
;;
;; Printing Multi-byte Buffer
;; --------------------------
;;
;; The variable `ps-multibyte-buffer' specifies the ps-print multi-byte buffer
;; handling.
;;
;; Valid values for `ps-multibyte-buffer' are:
;;
2007-07-25 14:57:09 +00:00
;; nil This is the value to use the default settings;
;; by default, this only works to print buffers with
;; only ASCII and Latin characters. But this default
;; setting can be changed by setting the variable
;; `ps-mule-font-info-database-default' differently.
;; The initial value of this variable is
;; `ps-mule-font-info-database-latin' (see
;; documentation).
;;
2007-07-25 14:57:09 +00:00
;; `non-latin-printer' This is the value to use when you have a japanese
;; or korean PostScript printer and want to print
;; buffer with ASCII, Latin-1, Japanese (JISX0208 and
;; JISX0201-Kana) and Korean characters. At present,
2007-07-25 14:57:09 +00:00
;; it was not tested with the Korean characters
;; printing. If you have a korean PostScript printer,
;; please, test it.
;;
2007-07-25 14:57:09 +00:00
;; `bdf-font' This is the value to use when you want to print
;; buffer with BDF fonts. BDF fonts include both latin
;; and non-latin fonts. BDF (Bitmap Distribution
;; Format) is a format used for distributing X's font
;; source file. BDF fonts are included in
;; `intlfonts-1.2' which is a collection of X11 fonts
;; for all characters supported by Emacs. In order to
;; use this value, be sure to have installed
;; `intlfonts-1.2' and set the variable
;; `bdf-directory-list' appropriately (see ps-bdf.el
;; for documentation of this variable).
;;
2007-07-25 14:57:09 +00:00
;; `bdf-font-except-latin' This is like `bdf-font' except that it uses
;; PostScript default fonts to print ASCII and Latin-1
;; characters. This is convenient when you want or
;; need to use both latin and non-latin characters on
;; the same buffer. See `ps-font-family',
;; `ps-header-font-family' and `ps-font-info-database'.
;;
;; Any other value is treated as nil.
;;
;; The default is nil.

2007-07-25 14:57:09 +00:00
(CHARSET (FONT-TYPE FONT-SRC FONT-NAME ENCODING BYTES) ...)
Where
CHARSET is a charset (symbol) for this font family,
FONT-TYPE is a font type: normal, bold, italic, or bold-italic.
FONT-SRC is a font source: builtin, bdf, vflib, or nil.
If FONT-SRC is builtin, FONT-NAME is a built-in PostScript font name.
If FONT-SRC is bdf, FONT-NAME is a BDF font file name, or a list of
alternative font names. To use this font, the external library `ps-bdf'
is required.
If FONT-SRC is vflib, FONT-NAME is the name of a font that VFlib knows.
To use this font, the external library `vflib' is required.
If FONT-SRC is nil, a proper ASCII font in the variable
2007-07-25 14:57:09 +00:00
`ps-font-info-database' is used. This is useful for Latin-1 characters.
2007-07-25 14:57:09 +00:00
ENCODING is a coding system to encode a string of characters of CHARSET into a
proper string matching an encoding of the specified font. ENCODING may be a
function that does this encoding. In this case, the function is called with
one argument, the string to encode, and it should return an encoded string.
2007-07-25 14:57:09 +00:00
BYTES specifies how many bytes each character has in the encoded byte
sequence; it should be 1 or 2.
All multi-byte characters are printed by fonts specified in this database
regardless of a font family of ASCII characters. The exception is Latin-1
characters which are printed by the same font as ASCII characters, thus obey
font family.
