577 | `unspecified'; this fact is not further mentioned below. | |

580 | ||
581 | `:family' | |
582 | ||
4b56d0fe CY |

584 | \(e.g. \"Monospace\") or a fontset. | |
5f5c8ee5 | 585 | |
fcea6e23 KH |
586 | `:foundry' |
587 | ||
588 | VALUE must be a string specifying the font foundry, | |
589 | e.g. ``adobe''. If a font foundry is specified, wild-cards `*' | |
590 | and `?' are allowed. | |
591 | ||
5f5c8ee5 GM |
592 | `:width' |
593 | ||
594 | VALUE specifies the relative proportionate width of the font to use. | |
595 | It must be one of the symbols `ultra-condensed', `extra-condensed', | |
596 | `condensed', `semi-condensed', `normal', `semi-expanded', `expanded', | |
597 | `extra-expanded', or `ultra-expanded'. | |
598 | ||
599 | `:height' | |
600 | ||
4b56d0fe CY |
601 | VALUE specifies the relative or absolute height of the font. An |
602 | absolute height is an integer, and specifies font height in units | |
603 | of 1/10 pt. A relative height is either a floating point number, | |
95838641 | 604 | which specifies a scaling factor for the underlying face height; |
4b56d0fe CY |
605 | or a function that takes a single argument (the underlying face |
606 | height) and returns the new height. Note that for the `default' | |
607 | face, you must specify an absolute height (since there is nothing | |
95838641 | 608 | for it to be relative to). |
5f5c8ee5 GM |
609 | |
610 | `:weight' | |
611 | ||
612 | VALUE specifies the weight of the font to use. It must be one of the | |
613 | symbols `ultra-bold', `extra-bold', `bold', `semi-bold', `normal', | |
614 | `semi-light', `light', `extra-light', `ultra-light'. | |
615 | ||
616 | `:slant' | |
617 | ||
618 | VALUE specifies the slant of the font to use. It must be one of the | |
619 | symbols `italic', `oblique', `normal', `reverse-italic', or | |
620 | `reverse-oblique'. | |
621 | ||
622 | `:foreground', `:background' | |
623 | ||
624 | VALUE must be a color name, a string. | |
625 | ||
626 | `:underline' | |
627 | ||
9b0e3eba AA |
628 | VALUE specifies whether characters in FACE should be underlined. |
629 | If VALUE is t, underline with foreground color of the face. | |
630 | If VALUE is a string, underline with that color. | |
631 | If VALUE is nil, explicitly don't underline. | |
632 | ||
633 | Otherwise, VALUE must be a property list of the form: | |
634 | ||
635 | `(:color COLOR :style STYLE)'. | |
636 | ||
637 | COLOR can be a either a color name string or `foreground-color'. | |
638 | STYLE can be either `line' or `wave'. | |
639 | If a keyword/value pair is missing from the property list, a | |
640 | default value will be used for the value. | |
641 | The default value of COLOR is the foreground color of the face. | |
642 | The default value of STYLE is `line'. | |
5f5c8ee5 GM |
643 | |
644 | `:overline' | |
645 | ||
646 | VALUE specifies whether characters in FACE should be overlined. If | |
647 | VALUE is t, overline with foreground color of the face. If VALUE is a | |
648 | string, overline with that color. If VALUE is nil, explicitly don't | |
649 | overline. | |
650 | ||
651 | `:strike-through' | |
652 | ||
653 | VALUE specifies whether characters in FACE should be drawn with a line | |
654 | striking through them. If VALUE is t, use the foreground color of the | |
655 | face. If VALUE is a string, strike-through with that color. If VALUE | |
656 | is nil, explicitly don't strike through. | |
657 | ||
658 | `:box' | |
659 | ||
660 | VALUE specifies whether characters in FACE should have a box drawn | |
661 | around them. If VALUE is nil, explicitly don't draw boxes. If | |
662 | VALUE is t, draw a box with lines of width 1 in the foreground color | |
663 | of the face. If VALUE is a string, the string must be a color name, | |
664 | and the box is drawn in that color with a line width of 1. Otherwise, | |
665 | VALUE must be a property list of the form `(:line-width WIDTH | |
666 | :color COLOR :style STYLE)'. If a keyword/value pair is missing from | |
667 | the property list, a default value will be used for the value, as | |
668 | specified below. WIDTH specifies the width of the lines to draw; it | |
0f937ebd KH |
669 | defaults to 1. If WIDTH is negative, the absolute value is the width |
670 | of the lines, and draw top/bottom lines inside the characters area, | |
671 | not around it. COLOR is the name of the color to draw in, default is | |
5f5c8ee5 GM |
672 | the foreground color of the face for simple boxes, and the background |
673 | color of the face for 3D boxes. STYLE specifies whether a 3D box | |
674 | should be draw. If STYLE is `released-button', draw a box looking | |
675 | like a released 3D button. If STYLE is `pressed-button' draw a box | |
676 | that appears like a pressed button. If STYLE is nil, the default if | |
677 | the property list doesn't contain a style specification, draw a 2D | |
678 | box. | |
679 | ||
680 | `:inverse-video' | |
681 | ||
682 | VALUE specifies whether characters in FACE should be displayed in | |
70d0c3b0 | 683 | inverse video. VALUE must be one of t or nil. |
5f5c8ee5 GM |
684 | |
685 | `:stipple' | |
686 | ||
687 | If VALUE is a string, it must be the name of a file of pixmap data. | |
688 | The directories listed in the `x-bitmap-file-path' variable are | |
689 | searched. Alternatively, VALUE may be a list of the form (WIDTH | |
690 | HEIGHT DATA) where WIDTH and HEIGHT are the size in pixels, and DATA | |
691 | is a string containing the raw bits of the bitmap. VALUE nil means | |
692 | explicitly don't use a stipple pattern. | |
693 | ||
fcea6e23 KH |
694 | For convenience, attributes `:family', `:foundry', `:width', |
695 | `:height', `:weight', and `:slant' may also be set in one step | |
696 | from an X font name: | |
5f5c8ee5 GM |
697 | |
698 | `:font' | |
699 | ||
4b56d0fe CY |
700 | Set font-related face attributes from VALUE. VALUE must be a |
701 | valid font name or font object. Setting this attribute will also | |
702 | set the `:family', `:foundry', `:width', `:height', `:weight', | |
703 | and `:slant' attributes. | |
19feb949 MB |
704 | |
705 | `:inherit' | |
706 | ||
4b56d0fe CY |
707 | VALUE is the name of a face from which to inherit attributes, or |
708 | a list of face names. Attributes from inherited faces are merged | |
709 | into the face like an underlying face would be, with higher | |
710 | priority than underlying faces. | |
711 | ||
712 | For backward compatibility, the keywords `:bold' and `:italic' | |
713 | can be used to specify weight and slant respectively. This usage | |
714 | is considered obsolete. For these two keywords, the VALUE must | |
715 | be either t or nil. A value of t for `:bold' is equivalent to | |
716 | setting `:weight' to `bold', and a value of t for `:italic' is | |
717 | equivalent to setting `:slant' to `italic'. But if `:weight' is | |
718 | specified in the face spec, `:bold' is ignored, and if `:slant' | |
719 | is specified, `:italic' is ignored." | |
