572 | `:family' | |
573 | ||
bfffdd07 | 574 | VALUE must be a string specifying the font family, e.g. ``monospace'', |

576 | and `?' are allowed. | |

578 | `:foundry' |

581 | e.g. ``adobe''. If a font foundry is specified, wild-cards `*' | |
582 | and `?' are allowed. | |
583 | ||
5f5c8ee5 GM |
584 | `:width' |
585 | ||
586 | VALUE specifies the relative proportionate width of the font to use. | |
587 | It must be one of the symbols `ultra-condensed', `extra-condensed', | |
588 | `condensed', `semi-condensed', `normal', `semi-expanded', `expanded', | |
589 | `extra-expanded', or `ultra-expanded'. | |
590 | ||
591 | `:height' | |
592 | ||
19feb949 MB |
593 | VALUE must be either an integer specifying the height of the font to use |
594 | in 1/10 pt, a floating point number specifying the amount by which to | |
595 | scale any underlying face, or a function, which is called with the old | |
596 | height (from the underlying face), and should return the new height. | |
5f5c8ee5 GM |
597 | |
598 | `:weight' | |
599 | ||
600 | VALUE specifies the weight of the font to use. It must be one of the | |
601 | symbols `ultra-bold', `extra-bold', `bold', `semi-bold', `normal', | |
602 | `semi-light', `light', `extra-light', `ultra-light'. | |
603 | ||
604 | `:slant' | |
605 | ||
606 | VALUE specifies the slant of the font to use. It must be one of the | |
607 | symbols `italic', `oblique', `normal', `reverse-italic', or | |
608 | `reverse-oblique'. | |
609 | ||
610 | `:foreground', `:background' | |
611 | ||
612 | VALUE must be a color name, a string. | |
613 | ||
614 | `:underline' | |
615 | ||
616 | VALUE specifies whether characters in FACE should be underlined. If | |
617 | VALUE is t, underline with foreground color of the face. If VALUE is | |
618 | a string, underline with that color. If VALUE is nil, explicitly | |
619 | don't underline. | |
620 | ||
621 | `:overline' | |
622 | ||
623 | VALUE specifies whether characters in FACE should be overlined. If | |
624 | VALUE is t, overline with foreground color of the face. If VALUE is a | |
625 | string, overline with that color. If VALUE is nil, explicitly don't | |
626 | overline. | |
627 | ||
628 | `:strike-through' | |
629 | ||
630 | VALUE specifies whether characters in FACE should be drawn with a line | |
631 | striking through them. If VALUE is t, use the foreground color of the | |
632 | face. If VALUE is a string, strike-through with that color. If VALUE | |
633 | is nil, explicitly don't strike through. | |
634 | ||
635 | `:box' | |
636 | ||
637 | VALUE specifies whether characters in FACE should have a box drawn | |
638 | around them. If VALUE is nil, explicitly don't draw boxes. If | |
639 | VALUE is t, draw a box with lines of width 1 in the foreground color | |
640 | of the face. If VALUE is a string, the string must be a color name, | |
641 | and the box is drawn in that color with a line width of 1. Otherwise, | |
642 | VALUE must be a property list of the form `(:line-width WIDTH | |
643 | :color COLOR :style STYLE)'. If a keyword/value pair is missing from | |
644 | the property list, a default value will be used for the value, as | |
645 | specified below. WIDTH specifies the width of the lines to draw; it | |
0f937ebd KH |
646 | defaults to 1. If WIDTH is negative, the absolute value is the width |
647 | of the lines, and draw top/bottom lines inside the characters area, | |
648 | not around it. COLOR is the name of the color to draw in, default is | |
5f5c8ee5 GM |
649 | the foreground color of the face for simple boxes, and the background |
650 | color of the face for 3D boxes. STYLE specifies whether a 3D box | |
651 | should be draw. If STYLE is `released-button', draw a box looking | |
652 | like a released 3D button. If STYLE is `pressed-button' draw a box | |
653 | that appears like a pressed button. If STYLE is nil, the default if | |
654 | the property list doesn't contain a style specification, draw a 2D | |
655 | box. | |
656 | ||
657 | `:inverse-video' | |
658 | ||
659 | VALUE specifies whether characters in FACE should be displayed in | |
70d0c3b0 | 660 | inverse video. VALUE must be one of t or nil. |
5f5c8ee5 GM |
661 | |
662 | `:stipple' | |
663 | ||
664 | If VALUE is a string, it must be the name of a file of pixmap data. | |
665 | The directories listed in the `x-bitmap-file-path' variable are | |
666 | searched. Alternatively, VALUE may be a list of the form (WIDTH | |
667 | HEIGHT DATA) where WIDTH and HEIGHT are the size in pixels, and DATA | |
668 | is a string containing the raw bits of the bitmap. VALUE nil means | |
669 | explicitly don't use a stipple pattern. | |
670 | ||
fcea6e23 KH |
671 | For convenience, attributes `:family', `:foundry', `:width', |
672 | `:height', `:weight', and `:slant' may also be set in one step | |
673 | from an X font name: | |
5f5c8ee5 GM |
674 | |
675 | `:font' | |
676 | ||
677 | Set font-related face attributes from VALUE. VALUE must be a valid | |
678 | XLFD font name. If it is a font name pattern, the first matching font | |
679 | will be used. | |
680 | ||
681 | For compatibility with Emacs 20, keywords `:bold' and `:italic' can | |
682 | be used to specify that a bold or italic font should be used. VALUE | |
19feb949 MB |
683 | must be t or nil in that case. A value of `unspecified' is not allowed. |
684 | ||
685 | `:inherit' | |
686 | ||
687 | VALUE is the name of a face from which to inherit attributes, or a list | |
688 | of face names. Attributes from inherited faces are merged into the face | |
689 | like an underlying face would be, with higher priority than underlying faces." | |
