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

146 "Alist of charsets with the corresponding font information.
147 Each element has the form:

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