586 VALUE must be a color name, a string.
590 VALUE specifies whether characters in FACE should be underlined. If
591 VALUE is t, underline with foreground color of the face. If VALUE is
592 a string, underline with that color. If VALUE is nil, explicitly
597 VALUE specifies whether characters in FACE should be overlined. If
598 VALUE is t, overline with foreground color of the face. If VALUE is a
599 string, overline with that color. If VALUE is nil, explicitly don't
604 VALUE specifies whether characters in FACE should be drawn with a line
605 striking through them. If VALUE is t, use the foreground color of the
606 face. If VALUE is a string, strike-through with that color. If VALUE
607 is nil, explicitly don't strike through.
611 VALUE specifies whether characters in FACE should have a box drawn
612 around them. If VALUE is nil, explicitly don't draw boxes. If
613 VALUE is t, draw a box with lines of width 1 in the foreground color
614 of the face. If VALUE is a string, the string must be a color name,
615 and the box is drawn in that color with a line width of 1. Otherwise,
616 VALUE must be a property list of the form `(:line-width WIDTH
617 :color COLOR :style STYLE)'. If a keyword/value pair is missing from
618 the property list, a default value will be used for the value, as
619 specified below. WIDTH specifies the width of the lines to draw; it
620 defaults to 1. If WIDTH is negative, the absolute value is the width
621 of the lines, and draw top/bottom lines inside the characters area,
622 not around it. COLOR is the name of the color to draw in, default is
623 the foreground color of the face for simple boxes, and the background
624 color of the face for 3D boxes. STYLE specifies whether a 3D box
625 should be draw. If STYLE is `released-button', draw a box looking
626 like a released 3D button. If STYLE is `pressed-button' draw a box
627 that appears like a pressed button. If STYLE is nil, the default if
628 the property list doesn't contain a style specification, draw a 2D
633 VALUE specifies whether characters in FACE should be displayed in
634 inverse video. VALUE must be one of t or nil.
638 If VALUE is a string, it must be the name of a file of pixmap data.
639 The directories listed in the `x-bitmap-file-path' variable are
640 searched. Alternatively, VALUE may be a list of the form (WIDTH
641 HEIGHT DATA) where WIDTH and HEIGHT are the size in pixels, and DATA
642 is a string containing the raw bits of the bitmap. VALUE nil means
643 explicitly don't use a stipple pattern.
645 For convenience, attributes `:family', `:width', `:height', `:weight',
646 and `:slant' may also be set in one step from an X font name:
650 Set font-related face attributes from VALUE. VALUE must be a valid
651 XLFD font name. If it is a font name pattern, the first matching font
654 For compatibility with Emacs 20, keywords `:bold' and `:italic' can
655 be used to specify that a bold or italic font should be used. VALUE
656 must be t or nil in that case. A value of `unspecified' is not allowed.
660 VALUE is the name of a face from which to inherit attributes, or a list
661 of face names. Attributes from inherited faces are merged into the face
662 like an underlying face would be, with higher priority than underlying faces."
