;; Printing Multi-byte Buffer
|
|
;; --------------------------
|
|
;;
|
|
;; The variable `ps-multibyte-buffer' specifies the ps-print multi-byte buffer
|
|
;; handling.
|
|
;;
|
|
;; Valid values for `ps-multibyte-buffer' are:
|
|
;;
|
|
;; 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).
|
|
;;
|
|
;; `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,
|
|
;; it was not tested with the Korean characters
|
|
;; printing. If you have a korean PostScript printer,
|
|
;; please, test it.
|
|
;;
|
|
;; `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

|
|
;; `intlfonts-1.2' and set the variable
|
|
;; `bdf-directory-list' appropriately (see ps-bdf.el
|
|
;; for documentation of this variable).
|

|
|
;; PostScript default fonts to print ASCII and Latin-1

|
|
Each element has the form:
|
|
|
|
(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
|
|
`ps-font-info-database' is used. This is useful for Latin-1 characters.
|
|
|
|
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.
|
|
|
|
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.
