22 /* New face implementation by Gerd Moellmann <gerd@gnu.org>. */
26 When using Emacs with X, the display style of characters can be
27 changed by defining `faces'. Each face can specify the following
32 2. Relative proportionate width, aka character set width or set
33 width (swidth), e.g. `semi-compressed'.
35 3. Font height in 1/10pt.
37 4. Font weight, e.g. `bold'.
39 5. Font slant, e.g. `italic'.
45 8. Whether or not characters should be underlined, and in what color.
47 9. Whether or not characters should be displayed in inverse video.
49 10. A background stipple, a bitmap.
51 11. Whether or not characters should be overlined, and in what color.
53 12. Whether or not characters should be strike-through, and in what
56 13. Whether or not a box should be drawn around characters, the box
57 type, and, for simple boxes, in what color.
59 14. Font or fontset pattern, or nil. This is a special attribute.
60 When this attribute is specified, the face uses a font opened by
61 that pattern as is. In addition, all the other font-related
62 attributes (1st thru 5th) are generated from the opened font name.
63 On the other hand, if one of the other font-related attributes are
64 specified, this attribute is set to nil. In that case, the face
65 doesn't inherit this attribute from the `default' face, and uses a
66 font determined by the other attributes (those may be inherited
67 from the `default' face).
69 15. A face name or list of face names from which to inherit attributes.
71 16. A specified average font width, which is invisible from Lisp,
72 and is used to ensure that a font specified on the command line,
73 for example, can be matched exactly.
75 Faces are frame-local by nature because Emacs allows to define the
76 same named face (face names are symbols) differently for different
77 frames. Each frame has an alist of face definitions for all named
78 faces. The value of a named face in such an alist is a Lisp vector
79 with the symbol `face' in slot 0, and a slot for each of the face
80 attributes mentioned above.
82 There is also a global face alist `Vface_new_frame_defaults'. Face
83 definitions from this list are used to initialize faces of newly
86 A face doesn't have to specify all attributes. Those not specified
87 have a value of `unspecified'. Faces specifying all attributes but
88 the 14th are called `fully-specified'.
93 The display style of a given character in the text is determined by
94 combining several faces. This process is called `face merging'.
95 Any aspect of the display style that isn't specified by overlays or
96 text properties is taken from the `default' face. Since it is made
97 sure that the default face is always fully-specified, face merging
98 always results in a fully-specified face.
103 After all face attributes for a character have been determined by
104 merging faces of that character, that face is `realized'. The
105 realization process maps face attributes to what is physically
106 available on the system where Emacs runs. The result is a
107 `realized face' in form of a struct face which is stored in the
108 face cache of the frame on which it was realized.
110 Face realization is done in the context of the character to display
111 because different fonts may be used for different characters. In
112 other words, for characters that have different font
113 specifications, different realized faces are needed to display
116 Font specification is done by fontsets. See the comment in
117 fontset.c for the details. In the current implementation, all ASCII
118 characters share the same font in a fontset.
120 Faces are at first realized for ASCII characters, and, at that
121 time, assigned a specific realized fontset. Hereafter, we call
122 such a face as `ASCII face'. When a face for a multibyte character
123 is realized, it inherits (thus shares) a fontset of an ASCII face
124 that has the same attributes other than font-related ones.
126 Thus, all realized face have a realized fontset.
131 Unibyte text (i.e. raw 8-bit characters) is displayed with the same
132 font as ASCII characters. That is because it is expected that
133 unibyte text users specify a font that is suitable both for ASCII
134 and raw 8-bit characters.
139 Font selection tries to find the best available matching font for a
140 given (character, face) combination.
142 If the face specifies a fontset name, that fontset determines a
143 pattern for fonts of the given character. If the face specifies a
144 font name or the other font-related attributes, a fontset is
145 realized from the default fontset. In that case, that
146 specification determines a pattern for ASCII characters and the
147 default fontset determines a pattern for multibyte characters.
149 Available fonts on the system on which Emacs runs are then matched
150 against the font pattern. The result of font selection is the best
151 match for the given face attributes in this font list.
153 Font selection can be influenced by the user.
155 1. The user can specify the relative importance he gives the face
156 attributes width, height, weight, and slant by setting
157 face-font-selection-order (faces.el) to a list of face attribute
158 names. The default is '(:width :height :weight :slant), and means
159 that font selection first tries to find a good match for the font
160 width specified by a face, then---within fonts with that
161 width---tries to find a best match for the specified font height,
164 2. Setting face-font-family-alternatives allows the user to
165 specify alternative font families to try if a family specified by a
168 3. Setting face-font-registry-alternatives allows the user to
169 specify all alternative font registries to try for a face
170 specifying a registry.
172 4. Setting face-ignored-fonts allows the user to ignore specific
176 Character composition.
178 Usually, the realization process is already finished when Emacs
179 actually reflects the desired glyph matrix on the screen. However,
180 on displaying a composition (sequence of characters to be composed
181 on the screen), a suitable font for the components of the
182 composition is selected and realized while drawing them on the
183 screen, i.e. the realization process is delayed but in principle
187 Initialization of basic faces.
189 The faces `default', `modeline' are considered `basic faces'.
190 When redisplay happens the first time for a newly created frame,
191 basic faces are realized for CHARSET_ASCII. Frame parameters are
192 used to fill in unspecified attributes of the default face. */
