31 ;; About ps-mule
32 ;; -------------
34 ;; This package is used for ps-print to print multi-byte buffer.
36 ;; See also ps-print.el.
39 ;; Printing Multi-byte Buffer
40 ;; --------------------------
42 ;; The variable `ps-multibyte-buffer' specifies the ps-print multi-byte buffer
43 ;; handling.
45 ;; Valid values for `ps-multibyte-buffer' are:
47 ;; nil This is the value to use the default settings;
48 ;; by default, this only works to print buffers with
49 ;; only ASCII and Latin characters. But this default
50 ;; setting can be changed by setting the variable
51 ;; `ps-mule-font-info-database-default' differently.
52 ;; The initial value of this variable is
53 ;; `ps-mule-font-info-database-latin' (see
54 ;; documentation).
56 ;; `non-latin-printer' This is the value to use when you have a japanese
57 ;; or korean PostScript printer and want to print
58 ;; buffer with ASCII, Latin-1, Japanese (JISX0208 and
59 ;; JISX0201-Kana) and Korean characters. At present,
60 ;; it was not tested with the Korean characters
61 ;; printing. If you have a korean PostScript printer,
62 ;; please, test it.
64 ;; `bdf-font' This is the value to use when you want to print
65 ;; buffer with BDF fonts. BDF fonts include both latin
66 ;; and non-latin fonts. BDF (Bitmap Distribution
67 ;; Format) is a format used for distributing X's font
68 ;; source file. BDF fonts are included in
69 ;; `intlfonts-1.2' which is a collection of X11 fonts
70 ;; for all characters supported by Emacs. In order to
71 ;; use this value, be sure to have installed
72 ;; `intlfonts-1.2' and set the variable
73 ;; `bdf-directory-list' appropriately (see ps-bdf.el
74 ;; for documentation of this variable).
76 ;; `bdf-font-except-latin' This is like `bdf-font' except that it uses
77 ;; PostScript default fonts to print ASCII and Latin-1
78 ;; characters. This is convenient when you want or
79 ;; need to use both latin and non-latin characters on
80 ;; the same buffer. See `ps-font-family',
81 ;; `ps-header-font-family' and `ps-font-info-database'.
83 ;; Any other value is treated as nil.
85 ;; The default is nil.

144 Each element has the form:

148 Where
150 CHARSET is a charset (symbol) for this font family,
152 FONT-TYPE is a font type: normal, bold, italic, or bold-italic.
154 FONT-SRC is a font source: builtin, bdf, vflib, or nil.
156 If FONT-SRC is builtin, FONT-NAME is a built-in PostScript font name.
158 If FONT-SRC is bdf, FONT-NAME is a BDF font file name, or a list of
159 alternative font names. To use this font, the external library `ps-bdf'
160 is required.
162 If FONT-SRC is vflib, FONT-NAME is the name of a font that VFlib knows.
163 To use this font, the external library `vflib' is required.
165 If FONT-SRC is nil, a proper ASCII font in the variable
166 `ps-font-info-database' is used. This is useful for Latin-1 characters.
168 ENCODING is a coding system to encode a string of characters of CHARSET into a
169 proper string matching an encoding of the specified font. ENCODING may be a
170 function that does this encoding. In this case, the function is called with
171 one argument, the string to encode, and it should return an encoded string.
173 BYTES specifies how many bytes each character has in the encoded byte
174 sequence; it should be 1 or 2.
176 All multi-byte characters are printed by fonts specified in this database
177 regardless of a font family of ASCII characters. The exception is Latin-1
178 characters which are printed by the same font as ASCII characters, thus obey
179 font family.
