antialiased fonts

antialiased fonts

[Rob Wilco]

Hello,

My Debian and Ubuntu boxes do not display the default antialiased Bitstream font within emacs. I am not sure but I think my mzndrake box used to do that.

I have put those lines in my .emacs

(defvar veramono "-bitstream-bitstream vera sans mono-*-*-*-*-*-*-*-*-*-*-*-*")
(add-to-list 'default-frame-alist (cons 'font veramono))

The font does change but it is not antialiased as is my mail client and my gnome-terminal.

I have googled the matter and it appears that emacs cannot display antialiased font.


Questions :

Is it true?

I don't get it, why gnome-terminal can do it and emacs can't?

Who antialiases font?

What does it takes to make a gtk-aware emacs à la gvim?

What process are involved xfs, defoma, Xorg/XFree86?

Any explanation, link, google keyword will be appreciated.

Good day.



PS : what are the goals of this ng compared to the one called comp.emacs ?

GNOME and GTK have a mechanism that reads a configuration file that  
names all fonts directories to be used. Then, when a GTK client is  
launched, another GTK mechanism checks whether any of these fonts has  
changed. If a change has happened, GTK spends the next few minutes to  
create cache files, fonts.cache-1 and .fonts.cache-1 in your home  
directory.

GNU Emacs relies on your X server. If it's font path is incorrect the X  
server won't be able to serve the same fonts as GTK can do. You can  
check the X server's setting with 'xset -q'. If you changes needed you  
can do them in your .xinitrc file, or what ever launches X for you at  
login. The syntax is simple:

	xset fp+  
/sw/share/ghostscript/fonts/,/sw/lib/X11/fonts/applettf/,/sw/lib/X11/ 
fonts/msttf/,/sw/lib/X11/fonts/efont-unicode/,/sw/lib/X11/fonts/intl/ 
TrueType/,/sw/lib/X11/fonts/intl/Type1/,/sw/lib/X11/fonts/intl/,/usr/ 
X11R6/lib/X11/fonts/bidi/,/usr/X11R6/lib/X11/fonts/Indian/,/sw/lib/X11/ 
fonts/efont-unicode/
	#
	xset fp rehash

The X server.

Get it from CVS, configure it --with-gtk, compile and install it  
yourself. (Check always ./configure --help!)

I think the development packages. defoma is a bit complicated to use,  
xfs is useful when you have one server that has all your fonts that its  
clients would like to use. This goes:

	xset fp+ inet/127.0.0.1:7101

In /usr/X11R6/bin you'll find some *-config executables. /etc/X11 will  
have configuration files.

Yes.

gnome-terminal was written to use GTK for rendering, which in turn
uses the X11 extension APIs for directly drawing antialiased fonts.
Emacs was written to use the plain X11 text drawing API, which does
not support antialiasing.

> Who antialiases font?

The X11 extension API (the name of which I cannot recall).

There are various degrees of GTK awareness. The current CVS, which
will someday be Emacs 22 has GTK widgets (menus, scrollbars etc), but
does not yet use GTK for drawing the text, since that is a much bigger
job requiring a complete fork of the display engine.

This newsgroup is for discussing topics specific to GNU
Emacs. comp.emacs.xemacs is the equivalent group for
XEmacs. comp.emacs is for topics that are common to both.

Has anyone ever seen antialiased font with emacs?  (correlary question : Was I drunk when I saw that with a Mandrake distrib?)

I googled a bit more, are you talking about xft for the X11 API?

If I follow the precedent post, my emacs would then be gtk-aware but still I would have unaliased fonts. Is that it?

Me. Many times.

First I use TrueType fonts. They get rendered and anti-aliased by the X 
server.

Second Carbon Emacs for Mac OS X uses a Quickdraw based anti-aliasing 
for scalable fonts too.


To see the difference either use in one frame a vector based font or 
fontset (TrueType or PostScript, or OpenType if your X server supports 
this) and use in another frame for example bitmapped fonts that GNU 
supplies since ages (-etl-fixed-*, too -schumacher-clean-*, 
-mutt-clearlyu-*). Or invoke C-h H and then check with C-u C-x = the 
glyphs.


There is another approach too possible: first invoke xlsfonts and list 
all monospaced fonts with iso10646-1 encoding, as an example, size: 
12pt or 14pt or 17pt. Among them you'll probably see patterns like this 
one: -0-0-. This pattern tells you that this font is built from a 
scalable (vector based) font, i.e. TrueType, PostScript, OpenType. The 
other fonts are bitmap based, come from bdf or pcf files. You can have 
Courier or Lucida Sans Typewriter in both formats -- and find whether 
you have anti-aliasing on your platform.

I have with my X server (XFree86 version: 4.3.0). And I do prefer the 
bitmapped fonts! They look sharp and crisp, the glyphs are perfectly 
exact positioned.

or NO.
http://savannah.gnu.org/cgi-bin/viewcvs/emacs/emacs/src/?only_with_tag=XFT_JHD_BRANCH

Using XFT_JHD_BRANCH in current cvs, emacs can display antialias font.
This branch is unstable (maybe).

No, the X server does not magically anti-alias TrueType fonts.
If you've seen Emacs anti-aliased on X11, I can only think of the
following reason:
- you ran Emacs inside an anti-aliased text-terminal-emulator.
- you tried one of the patches that add support for xft, none of which is
  in any kind of stable state, AFAIK (tho I haven't tried to xft branch in
  the CVS repository recently).

Great news, I have hope.

I have read the thorougly read this thread and I have many questions 
(and still no antialiased fonts !).



I wish to use Bitstream Vera Sans Mono for the antialised font. I am 
pretty sure it is an TrueType font that can be antialiased because every 
file related to "bitstream" is in a ttf folder.

  * How to be sure a font is TrueType or bitmap? Can xfontsel of xslfont 
tell if a font is TrueType or Bitmap or else?



I assume that if Gnome displays antialiased fonts then my X supports it. 
(because gtk uses XFT).

  * Am I right with that?


With your advice, I have set the following font in .emacs (my .emacs is 
minimal, it only contains the following two lines):

(defvar veramono "-bitstream-bitstream vera sans 
mono-medium-r-normal--0-0-0-0-m-0-iso10646-1")
(add-to-list 'default-frame-alist (cons 'font veramono))

And actually, the font looks like my default system font, except that it 
is not antialiased (and ugly on a lcd screen).

  * What did I miss ?




I tried "M-x apropos: fonts" but tons of entries and several are 
functions unavailable on my system. (I tried M-x then "x-" and then TAB 
but there only x-set-selection while "M-x apropos: fonts" says there are 
lots of functions beginning with x-font-*)

  * How can I change fonts on the fly with emacs?



> Or invoke C-h H and then check with C-u C-x = the 
> glyphs.

If I type C-h H C-u C-x =, then I do get "Hello" in several langage and 
informations on the font used where the point is.

None of those are anti aliased.

  * What do you mean by check the glyphs?  What does it teaches me?

That's not enough reason. Look at the file's extension, could be some 
part of your system (the file command, Nautilus, etc.) can determine 
more exactly the nature of these files. There too is fontforge, once 
knows as pfaedit. But Vera Sans comes as TrueType!

No. They just report what the X server (or X font server) has told 
them. To determine the nature and the contents of a font file you need 
fontforge, once knows as pfaedit.

Yes, your X server has an extension to render the scalable fonts as 
anti-aliased ones. Now the question is whether all its clients can use 
this ability ...

This definition is a bit better (but check first, whether you have the 
other iso8859 encodings too):

     (create-fontset-from-fontset-spec "-*-bitstream vera sans 
mono-medium-r-*-*-10-*-*-*-*-*-fontset-10pt_vera_sans_mono" t 'noerror)
	(set-fontset-font "fontset-10pt_vera_sans_mono"       'latin-iso8859-1 
  '("bitstream vera sans mono" . "iso8859-1"))
	(set-fontset-font "fontset-10pt_vera_sans_mono"       'latin-iso8859-2 
  '("bitstream vera sans mono" . "iso10646-1"))
	(set-fontset-font "fontset-10pt_vera_sans_mono"       'latin-iso8859-3 
  '("bitstream vera sans mono" . "iso10646-1"))
	(set-fontset-font "fontset-10pt_vera_sans_mono"       'latin-iso8859-4 
  '("bitstream vera sans mono" . "iso10646-1"))
	(set-fontset-font "fontset-10pt_vera_sans_mono"       'latin-iso8859-9 
  '("bitstream vera sans mono" . "iso8859-9"))
	(set-fontset-font "fontset-10pt_vera_sans_mono"       
'latin-iso8859-15 '("bitstream vera sans mono" . "iso8859-15"))
	(set-fontset-font "fontset-10pt_vera_sans_mono" 
'mule-unicode-0100-24ff '("bitstream vera sans mono" . "iso10646-1"))
	(set-fontset-font "fontset-10pt_vera_sans_mono" 
'mule-unicode-2500-33ff '("bitstream vera sans mono" . "iso10646-1"))
	(set-fontset-font "fontset-10pt_vera_sans_mono" 
'mule-unicode-e000-ffff '("bitstream vera sans mono" . "iso10646-1"))


You too could try to extend the list of fonts:

S-mouse-1 pops up a menu from which you can select fonts or fontsets.

A more capable X server, one that serves anti-aliased fonts to non-GTK 
clients too? A version of GNU Emacs from CVS? At least you could try 
that. I do not use Linux, so I can't tell you more exactly what might 
be wrong with your system ...

M-x set-frame-font RET TAB TAB C-g, the return to the *completions* 
buffer and save it, to have it safe and less volatile. Ahemm -- don't 
try to expand the name of the file to save the list of completions in: 
this will substitute the *completions* buffer with a completely 
different contents!

You can see from which font the glyphs are taken from. With this 
knowledge you then can tell whether it's a scalable or a fixed bitmap 
font.

OK, I confess: with X11 I do *not* see antialiased fonts! My xterm is 
GTK aware (whenever I changed my number of fonts it took minutes until 
it showed up!). Using the font or on that font based fontset I actually 
can see differences between both. In xterm I can see that some pixels 
are not completely dark, in Emacs this never happens, no matter how 
steep or how round a line is, all pixels are really black.

So there is really only one stable release of GNU Emacs that can 
anti-alias fonts: Carbon Emacs 22.0.50 from CVS for Mac OS X.

No, there's also:
- Emacs under an anti-aliased tty
- and of course NTEmacs

That is like saying that there is only one string instrument with
valves, and that is the trumpet.
