27 The m17n GUI API represents a font by an object of the type @c
28 MFont. A font can have @e font @e properties. Like other types
29 of properties, a font property consists of a key and a value. The
30 key of a font property must be one of the following symbols:
32 @c Mfoundry, @c Mfamily, @c Mweight, @c Mstyle, @c Mstretch,
33 @c Madstyle, @c Mregistry, @c Msize, @c Mresolution.
35 When the key of a font property is @c Msize or @c Mresolution, its
36 value is an integer. Otherwise the value is a symbol. "The font
37 property that belongs to font F and whose key is @c Mxxx" may be
38 shortened to "the xxx property of F".
40 The value of a foundry property is a symbol representing font
41 foundry information, e.g. adobe, misc, etc.
43 The value of a family property is a symbol representing font family
44 information, e.g. times, helvetica, etc.
46 The value of a weight property is a symbol representing weight
47 information, e.g. normal, bold, etc.
49 The value of a style property is a symbol representing slant
50 information, e.g. normal, italic, etc.
52 The value of a stretch property is a symbol representing width
53 information, e.g. normal, semicondensed, etc.
55 The value of an adstyle property is a symbol representing abstract
56 font family information, e.g. serif, sans-serif, etc.
58 The value of a registry property is a symbol representing registry
59 information, e.g. iso10646-1, iso8895-1, etc.
61 The value of a size property is an integer representing design
62 size in the unit of 1/10 point.
64 The value of a resolution property is an integer representing
65 assumed device resolution in the unit of dots per inch (dpi)
67 The m17n library uses font objects for two purposes: to receive
68 font specification from an application program, and to present
69 available fonts to an application program. When the m17n library
70 presents an available font to an application program, all font
71 properties have a concrete value.
73 The m17n library supports three kinds of fonts: Window system fonts,
74 FreeType fonts, and OpenType fonts.
78 <li> Window system fonts
80 The m17n-X library supports all fonts handled by an X server and
81 an X font server. The correspondence between XLFD fields and font
82 properties are shown below.
86 --------------- --------
92 ADD_STYLE_NAME adstyle
94 RESOLUTION_Y resolution
95 CHARSET_REGISTRY-CHARSET_ENCODING registry
98 XLFD fields not listed in the above table are ignored.
102 The m17n library, if configured to use the FreeType library,
103 supports all fonts that can be handled by the FreeType library.
104 The variable #mfont_freetype_path is initialized properly according
105 to the configuration of the m17n library and the environment
106 variable @c M17NDIR. See the documentation of the variable for
109 If the m17n library is configured to use the Xft librray, in
110 addition to #mfont_freetype_path, all fonts available via
111 fontconfig are supported.
113 The family name of a FreeType font corresponds to the family
114 property. Style names of FreeType fonts correspond to the weight,
115 style, and stretch properties as below.
118 style name weight style stretch
119 ---------- ------ ----- -------
120 Regular medium r normal
121 Italic medium i normal
123 Bold Italic bold i normal
124 Narrow medium r condensed
125 Narrow Italic medium i condensed
126 Narrow Bold bold r condensed
127 Narrow Bold Italic bold i condensed
129 Black Italic black i normal
130 Oblique medium o normal
131 BoldOblique bold o normal
134 Style names not listed in the above table are treated as
137 Combination of a platform ID and an encoding ID corresponds to the
138 registry property. For example, if a font has the combination (1
139 1), the registry property is 1-1. Some frequent combinations have
140 a predefined registry property as below.
143 platform ID encoding ID registry property
144 ----------- ----------- -----------------
152 Thus, a font that has two combinations (1 0) and (3 1) corresponds
153 to four font objects whose registries are 1-0, apple-roman, 3-1,
158 The m17n library, if configured to use both the FreeType library
159 and the OTF library, supports any OpenType fonts. The list of
160 actually available fonts is created in the same way as in the case
161 of FreeType fonts. If a fontset instructs to use an OpenType font
162 via an FLT (Font Layout Table), and the FLT has an OTF-related
163 command (e.g. otf:deva), the OTF library converts a character
164 sequence to a glyph code sequence according to the OpenType layout
165 tables of the font, and the FreeType library gives a bitmap image

1321 the element is @c Mstring, and the value is a string that

1327 internal list of the actually available fonts from this variable.
1328 Thus, an application program, if necessary, must modify the
1329 variable before calling mframe (). If it is going to add a new
1330 element, value must be a string that can be safely freed.
