make ps-print-buffer-with-faces all bold

[myglc2]

I alway want emacs printout in color but find the 'normal' faces
frustratingly unreadable, especially in low contrast colors. So... Here
is how to make everything bold in ps-print-buffer-with-faces, etc.

;; ps-print in all bold fonts
(ps-extend-face-list
(mapcar (function (lambda (x) (list x
(face-attribute x :foreground)
(face-attribute x :background)
'bold)))
(face-list)) 'MERGE)

Cool, but perhaps you should change the "low
contrast colors" instead? Or do they look good
on the screen, only not so when printed?

In what context should one use the code? I.e.,
do you run it once or every time you print?

And: I don't think you need `function' before
`lambda'.

Last, aren't there other attributes than
foreground and background? Perhaps you can find
a function that returns the whole thing, and
then just set it to bold?

Otherwise keep it up...

To print I use a light theme and I want color to match the screen. Dark
themes are generally unreadable printed this way. Something clever needs
to be done with the color if you want to print dark themes.

On my printer normal fonts are ~ unreadable.

emacs init file.

elisp noobie ;-)

The ps-print.el public interface requires this custom structure.

OK, because if you use `describe-function' you
get a whole lot of stuff!

But perhaps PostScript in this case (?) only
uses what you mention?

Actually it all I use for faces. Foreground,
background, and bold or not (the foreground).

(modify-face 'erc-header-line "white" "magenta" nil t)

The fourth argument is the foreground boldness;
the third is "stipple".

A lot of the properties are not supported in
the Linux VTs. Maybe they look cool in X?

Ironic thing is, rms wanted to make Emacs
a word processor for the masses. Instead it
stayed, and became even more so, a text editor
and programming tool for the computer elite.

Restating the function under discussion for handy reference ...

;; ps-print in all bold fonts
(ps-extend-face-list
(mapcar (function (lambda (x) (list x
(face-attribute x :foreground)
(face-attribute x :background)
'bold)))
(face-list)) 'MERGE)

OK I think I missed your earlier point. Yes, you can specify additional
attributes, to the extent that ps-print supports them, using the
'ps-extend-face-list' interface.

The reason I specify the colors is that with nil or t for foreground and
background, ps-print prints in B&W. So this function re-states the
colors that ps-print already knows about in order to bold the faces w/o
clobbering the color. HTH - George
