432 ARGS must come in pairs ATTRIBUTE VALUE. ATTRIBUTE must be a valid
433 face attribute name. All attributes can be set to `unspecified';
434 this fact is not further mentioned below.
436 The following attributes are recognized:
440 VALUE must be a string specifying the font family, e.g. ``courier'',
441 or a fontset alias name. If a font family is specified, wild-cards `*'
446 VALUE specifies the relative proportionate width of the font to use.
447 It must be one of the symbols `ultra-condensed', `extra-condensed',
448 `condensed', `semi-condensed', `normal', `semi-expanded', `expanded',
449 `extra-expanded', or `ultra-expanded'.
453 VALUE must be an integer specifying the height of the font to use in
458 VALUE specifies the weight of the font to use. It must be one of the
459 symbols `ultra-bold', `extra-bold', `bold', `semi-bold', `normal',
460 `semi-light', `light', `extra-light', `ultra-light'.
464 VALUE specifies the slant of the font to use. It must be one of the
465 symbols `italic', `oblique', `normal', `reverse-italic', or
468 `:foreground', `:background'
470 VALUE must be a color name, a string.
474 VALUE specifies whether characters in FACE should be underlined. If
475 VALUE is t, underline with foreground color of the face. If VALUE is
476 a string, underline with that color. If VALUE is nil, explicitly
481 VALUE specifies whether characters in FACE should be overlined. If
482 VALUE is t, overline with foreground color of the face. If VALUE is a
483 string, overline with that color. If VALUE is nil, explicitly don't
488 VALUE specifies whether characters in FACE should be drawn with a line
489 striking through them. If VALUE is t, use the foreground color of the
490 face. If VALUE is a string, strike-through with that color. If VALUE
491 is nil, explicitly don't strike through.
495 VALUE specifies whether characters in FACE should have a box drawn
496 around them. If VALUE is nil, explicitly don't draw boxes. If
497 VALUE is t, draw a box with lines of width 1 in the foreground color
498 of the face. If VALUE is a string, the string must be a color name,
499 and the box is drawn in that color with a line width of 1. Otherwise,
500 VALUE must be a property list of the form `(:line-width WIDTH
501 :color COLOR :style STYLE)'. If a keyword/value pair is missing from
502 the property list, a default value will be used for the value, as
503 specified below. WIDTH specifies the width of the lines to draw; it
504 defaults to 1. COLOR is the name of the color to draw in, default is
505 the foreground color of the face for simple boxes, and the background
506 color of the face for 3D boxes. STYLE specifies whether a 3D box
507 should be draw. If STYLE is `released-button', draw a box looking
508 like a released 3D button. If STYLE is `pressed-button' draw a box
509 that appears like a pressed button. If STYLE is nil, the default if
510 the property list doesn't contain a style specification, draw a 2D
515 VALUE specifies whether characters in FACE should be displayed in
516 inverse video. VALUE must be one of t or nil.
520 If VALUE is a string, it must be the name of a file of pixmap data.
521 The directories listed in the `x-bitmap-file-path' variable are
522 searched. Alternatively, VALUE may be a list of the form (WIDTH
523 HEIGHT DATA) where WIDTH and HEIGHT are the size in pixels, and DATA
524 is a string containing the raw bits of the bitmap. VALUE nil means
525 explicitly don't use a stipple pattern.
527 For convenience, attributes `:family', `:width', `:height', `:weight',
528 and `:slant' may also be set in one step from an X font name:
532 Set font-related face attributes from VALUE. VALUE must be a valid
533 XLFD font name. If it is a font name pattern, the first matching font
536 For compatibility with Emacs 20, keywords `:bold' and `:italic' can
537 be used to specify that a bold or italic font should be used. VALUE
538 must be t or nil in that case. A value of `unspecified' is not allowed."
