What determines the available font sizes?

What determines the available font sizes?

[Chris Page]

What determines which font sizes are available to emacs? Is there some 
finite set of sizes it supports?

I'd like to use Monaco 11 on Mac OS X, but I can only seem to get 10 and 
12 pt sizes. If I define a fontset for Monaco 11, or customize a face to 
use "monaco" "110", it gets displayed the same as 10 or 12. There 
doesn't seem to be a way to access Monaco at 11 pts.

The syntax you use! These example allow the use of (almost) any size:

(create-fontset-from-mac-roman-font 
"-*-monaco-medium-r-*-*-10-*-*-*-*-*-mac-roman"   	   	     	  nil 
"10pt_monaco")
(create-fontset-from-mac-roman-font 
"-*-monaco-medium-r-*-*-11-*-*-*-*-*-mac-roman"   	   	     	  nil 
"11pt_monaco")

With create-fontset-from-fontset-spec there certainly is. I think this 
function can only retrieve the bitmapped fonts from a font suitcase.

Thanks, but as I said, I tried creating fontsets. The issue is that 
Monaco 11 isn't apparently supported.

Well, I suppose that's my answer, then. There is no bitmap for 11pt 
Monaco, I don't think. Then again, I'm using Aquamacs, which uses 
anti-aliased outline fonts. I suppose it's still limiting the available 
font sizes to those with bitmaps. I wonder how I might overcome that 
unfortunate limitation.

The big question is now: how to include, say, a scalable cyrillic  
font in a font set in arbitrary font sizes?
create-fontset-from-mac-roman-font seems to support only ASCII fonts,  
as it uses create-fontset-from-ascii-font.

Since my own cyrillic is quite bad, I can only tell you that my ISO  
8859-5 test file looks in Carbon Emacs 22 in this fontset and in GNU  
Emacs 23 (Unicode Emacs, X11) in any other fontset quite alike ... (ISO  
8859-2 not!)

Sure that'll include the font, but not in an arbitrary size, will it?
Arbitrary as in: I set the size, not as in: Emacs or whoever choses  
some size.

How do I set the size for it then?

I hoped you would do some experiments with the fontset definition -- I  
did some time ago when I tried to re-write and enhance my own fontset  
definitions and so I found that Cyrillic and Central European glyphs  
could scale from some points (almost invisible 5) up to 50. The other  
Latin glyphs only scaled in discrete steps, hence I think of those  
bloody bitmaps! One cure could be to clean up Monaco.dfont from the  
bitmapped fonts ...


There can be other reasons too. Pfaedit tells me:

	Warning: Glyph 284 is named Gcedilla which should mean it is mapped to
	 Unicode U+0122, but Glyph 360 already has that encoding.
	Bad lookup table format=8, first=32 cnt=778 total glyphs in font=810

Could be this makes the use of the scalable TT glyphs impossible ...

Here's one of my stripped-down lines:

           cyrillic-iso8859-5:-*-monaco  
cy-medium-r-normal--63-*-*-*-m-*-mac-*,

Bitstream Courier, i.e.  
-*-courier-medium-r-normal--*-*-*-*-m-*-mac-roman, is easy scalable.

You can add this to your file ~/Library/Preferens/Aquamacs Emacs/ 
Preferences.el :

(condition-case e
     (create-fontset-from-fontset-spec
      "-apple-monaco*-medium-r-normal--11-*-*-*-*-*-fontset-monaco11,
     ascii:-apple-monaco*-medium-r-normal--11-110-75-75-m-120-mac-*,
     latin-iso8859-1:-apple-monaco*-medium-r-normal--11-110-75-75- 
m-120-mac-*,
     latin-iso8859-9:-apple-monaco*-medium-r-normal--11-110-75-75- 
m-120-mac-*,
     utf-8:-apple-monaco*-medium-r-normal--11-110-75-75-m-120-mac-*,
     " nil t)
   (error (print (list "Warning: " e))))


That should give you a size 11.
Peter's solution should work, too.
