444 | ||
445 | VALUE specifies the relative proportionate width of the font to use. | |
446 | It must be one of the symbols `ultra-condensed', `extra-condensed', | |
447 | `condensed', `semi-condensed', `normal', `semi-expanded', `expanded', | |
448 | `extra-expanded', or `ultra-expanded'. | |
449 | ||
450 | `:height' | |
451 | ||
452 | VALUE must be an integer specifying the height of the font to use in | |
453 | 1/10 pt. | |
454 | ||
455 | `:weight' | |
456 | ||
457 | VALUE specifies the weight of the font to use. It must be one of the | |
458 | symbols `ultra-bold', `extra-bold', `bold', `semi-bold', `normal', | |
459 | `semi-light', `light', `extra-light', `ultra-light'. | |
460 | ||
461 | `:slant' | |
462 | ||
463 | VALUE specifies the slant of the font to use. It must be one of the | |
464 | symbols `italic', `oblique', `normal', `reverse-italic', or | |
465 | `reverse-oblique'. | |
466 | ||
467 | `:foreground', `:background' | |
468 | ||
469 | VALUE must be a color name, a string. | |
470 | ||
471 | `:underline' | |
472 | ||
473 | VALUE specifies whether characters in FACE should be underlined. If | |
474 | VALUE is t, underline with foreground color of the face. If VALUE is | |
475 | a string, underline with that color. If VALUE is nil, explicitly | |
476 | don't underline. | |
477 | ||
478 | `:overline' | |
479 | ||
480 | VALUE specifies whether characters in FACE should be overlined. If | |
481 | VALUE is t, overline with foreground color of the face. If VALUE is a | |
482 | string, overline with that color. If VALUE is nil, explicitly don't | |
483 | overline. | |
484 | ||
485 | `:strike-through' | |
486 | ||
487 | VALUE specifies whether characters in FACE should be drawn with a line | |
488 | striking through them. If VALUE is t, use the foreground color of the | |
489 | face. If VALUE is a string, strike-through with that color. If VALUE | |
490 | is nil, explicitly don't strike through. | |
491 | ||
492 | `:box' | |
493 | ||
494 | VALUE specifies whether characters in FACE should have a box drawn | |
495 | around them. If VALUE is nil, explicitly don't draw boxes. If | |
496 | VALUE is t, draw a box with lines of width 1 in the foreground color | |
497 | of the face. If VALUE is a string, the string must be a color name, | |
498 | and the box is drawn in that color with a line width of 1. Otherwise, | |
499 | VALUE must be a property list of the form `(:line-width WIDTH | |
500 | :color COLOR :style STYLE)'. If a keyword/value pair is missing from | |
501 | the property list, a default value will be used for the value, as | |
502 | specified below. WIDTH specifies the width of the lines to draw; it | |
503 | defaults to 1. COLOR is the name of the color to draw in, default is | |
504 | the foreground color of the face for simple boxes, and the background | |
505 | color of the face for 3D boxes. STYLE specifies whether a 3D box | |
506 | should be draw. If STYLE is `released-button', draw a box looking | |
507 | like a released 3D button. If STYLE is `pressed-button' draw a box | |
508 | that appears like a pressed button. If STYLE is nil, the default if | |
509 | the property list doesn't contain a style specification, draw a 2D | |
510 | box. | |
511 | ||
512 | `:inverse-video' | |
513 | ||
514 | VALUE specifies whether characters in FACE should be displayed in | |
515 | inverse video. VALUE must be one of t or nil. | |
516 | ||
517 | `:stipple' | |
518 | ||
519 | If VALUE is a string, it must be the name of a file of pixmap data. | |
520 | The directories listed in the `x-bitmap-file-path' variable are | |
521 | searched. Alternatively, VALUE may be a list of the form (WIDTH | |
522 | HEIGHT DATA) where WIDTH and HEIGHT are the size in pixels, and DATA | |
523 | is a string containing the raw bits of the bitmap. VALUE nil means | |
524 | explicitly don't use a stipple pattern. | |
525 | ||
526 | For convenience, attributes `:family', `:width', `:height', `:weight', | |
527 | and `:slant' may also be set in one step from an X font name: | |
528 | ||
529 | `:font' | |
530 | ||
531 | Set font-related face attributes from VALUE. VALUE must be a valid | |
532 | XLFD font name. If it is a font name pattern, the first matching font | |
533 | will be used. | |
534 | ||
535 | For compatibility with Emacs 20, keywords `:bold' and `:italic' can | |
536 | be used to specify that a bold or italic font should be used. VALUE | |
537 | must be t or nil in that case. A value of `unspecified' is not allowed." | |
