Turn off anti-alias for font in Emacs 23

Question

How to I disable anti-aliasing for fonts in the Windows version of Emacs 23?

Thanks.

Good question - Google was no help. Id like to know how to do this under X11? (The answer below is Windows only.) — multipolygon, Feb 20 '10 at 05:55

You can specify the antialias=none option for your fonts, as stated in GNU Emacs Manual

More explicitly, you hit `M-x customize` and then choose `Faces` and again `Basic Faces`. There you will find the default face where you can turn off the anti-aliasing. – Pinochle Aug 14 '09 at 20:17

As I couldn't find a satisfactory answer to this one for a long time, I thought it wouldn't hurt to add this link to this discussion, as the above does not generally work on Linux:

The problem is that under Linux, emacs doesn't seem to be doing a lot of font handling at all, and you need to disable the antialiasing elsewhere.

-1 because it doesn't answer the question as asked here (please open a new question that you answer yourself), and the link is useless since it's not a permalink to a specific item. – fluffy Oct 01 '12 at 18:01

If others were searching for how to disable anti-aliasing in OS X, you can run

Works for me as of 2018 in Mojave – rat Oct 03 '18 at 15:43
This worked for me for default font, but bold fonts were still antialiased until added this to .emacs: ```(setq-default mac-allow-anti-aliasing nil)``` – kcraigie May 24 '19 at 18:05

Never have run Mac OS X, so usable only for Linux + Windows:

(defvar my-preferred-font
  (cond
   ((eq window-system 'x)
    "-misc-fixed-medium-r-normal--14-*-*-*-c-*-iso10646-1")
   ((eq window-system 'w32)
    "Courier New-10:antialias=none")
   (t nil)))
(when my-preferred-font
  (set-frame-font my-preferred-font)
  (set-fontset-font "fontset-default" 'latin my-preferred-font)
  (set-fontset-font "fontset-default" 'phonetic my-preferred-font)
  (set-fontset-font "fontset-default" 'cyrillic my-preferred-font)
  (set-fontset-font "fontset-default" 'greek my-preferred-font))

Whose uses only ASCII it is enough to follow official suggestion:

(add-to-list 'default-frame-alist '(font . "Courier New-10:antialias=none"))

I work with cyrillic, greek and IPA texts so need to define defaults for fontsets...
