It's been some time since I wrote it, I was keeping it in the fridge waiting for the version fork. This new face property is called `stippled', and gives text, well, a stippled look, like text displayed in Motif-like insensitive widgets. This works only under X. Here's a picture of what you get when applying it to the widget-inactive face: ------------------------------------------------------------------------ [Image] ------------------------------------------------------------------------ I've also updated Custom. Lisp changelog: ============== 1998-07-17 Didier Verna <verna(a)inf.enst.fr&gt; * faces.el (set-face-property): updated the doc string for the stippled property. (face-stippled-p): new function. (set-face-stippled-p): ditto. (face-equal): handle the new stippled property. * cus-face.el (custom-face-attributes): New face attribute: `stippled' Renamed the `stipple' attribute to `background-pixmap'. (custom-face-background-pixmap): make custom-face-stipple an obsolete alias for this. C changelog: =========== 1998-07-17 Didier Verna <verna(a)inf.enst.fr&gt; * lisp.h: declare the lisp symbol `Qstippled' * redisplay-x.c (x_get_gc): returns a GC with a FillStipple fill style as foreground GC for faces that have the `stippled' property. (x_output_string): when the `stippled' face property is set, ensure the gray pixmap has been created, and get a proper foreground GC to draw the text. * faces.c (mark_face): update for the `stippled' field (face_equal): ditto. (face_getprop): ditto. (face_putprop): ditto. (face_remprop): ditto. (face_plist): ditto. (reset_face): ditto. (update_face_inheritance_mapper): ditto. (Fmake_face): ditto. (update_face_cachel_data): ditto. (merge_face_cachel_data): ditto. (Fcopy_face): ditto. (complex_vars_of_faces): ditto. (syms_of_faces): define lisp symbol `Qstippled' (vars_of_faces): add Qstippled to the built-in face specifiers * faces.h (struct Lisp_Face): new field `stippled'. (struct face_cachel): new fields `stippled' and `stippled specified' plus some convenience macros. --- lisp/cus-face.el.orig Fri Jul 17 13:33:51 1998 +++ lisp/cus-face.el Fri Jul 17 14:04:50 1998 ＠＠ -67,13 +67,15 ＠＠ :help-echo "\ Text size (e.g. 9pt or 2mm).") custom-set-face-font-size custom-face-font-size) - (:stipple (editable-field :format "Stipple: %v" - :help-echo "Name of background bitmap file.") - set-face-stipple custom-face-stipple) (:family (editable-field :format "Font Family: %v" :help-echo "\ Name of font family to use (e.g. times).") custom-set-face-font-family custom-face-font-family) + (:background-pixmap (editable-field + :format "Background pixmap: %v" + :help-echo "Name of background pixmap file.") + set-face-background-pixmap + custom-face-background-pixmap) (:bold (toggle :format "%[Bold%]: %v\n" :help-echo "Control whether a bold font should be used.") custom-set-face-bold custom-face-bold) ＠＠ -81,6 +83,10 ＠＠ :help-echo "\ Control whether an italic font should be used.") custom-set-face-italic custom-face-italic) + (:stippled (toggle :format "%[Stippled%]: %v\n" + :help-echo "\ +Control whether the text should appear stippled.") + set-face-stippled-p face-stippled-p) (:underline (toggle :format "%[Underline%]: %v\n" :help-echo "\ Control whether the text should be underlined.") ＠＠ -178,12 +184,14 ＠＠ (fontobj (font-create-object font))) (font-italic-p fontobj))) -(defun custom-face-stipple (face &rest args) - "Return the name of the stipple file used for FACE." +(defun custom-face-background-pixmap (face &rest args) + "Return the name of the background pixmap file used for FACE."

I agree with Ben about 'stippled' being a bad property name. I disagree about obsoleting the tty 'dim' property. I think we should make the 'dim' property be what Didier calls 'stippled' on X devices and of course leave 'dim' as it is now on TTY devices.
