Complicated, but not a necessity for what we will be doing,. Thanks for the
advice.

How does that relate to *using* the Freetype libraries on a particular
platform Andy?

A default build of the FreeType libraries has the sub-pixel rendering 
disabled. It also has the truetype hinting disabled (this is subject to 
another patent, this time held by Apple).

It is possible to re-compile the freetype libraries so that the sub-pixel 
rendering (and/or truetype hinting is enabled). I believe that the libraries

installed by the FreeType Plus packages are the standard ones, and thus 
don't contain any patented code.

In any case, I don't use FreeType's built in support for sub-pixel 
anti-aliasing. Instead, I manually stretch, and filter, the glyphs in 
Smalltalk code. And this only happens when the optional FreeType plus 
sub-pixel anti-aliasing package is installed.

Microsoft are happy to sell licenses for ClearType at $1 to $3 per device 
(but does that mean that on Windows and Mac the user already has a license? 
or is it really per application? I don't know).

The best advice I can give is to distribute applications without the 
sub-pixel package installed. You can still use FreeType, but the glyphs will

be grayscale anti-aliased, not sub-pixel anti-aliased.

I also understand that these patent restrictions do not apply in all 
jurisdications, which is another thing to consider.

Hope that helps,
Cheers,
Andy

I believe that, before adding any form of sub-pixel anti-aliased glyph
rendering to an official distribution, the patent/license situation
surrounding such technologies should be considered by the ReleaseTeam and/or

the Board.

For a very clear and concise appraisal, please see
http://david.freetype.org/cleartype-patents.html

I have chosen to separate the sub-pixel aa parts of the FreeType Plus
packages from the patent free parts. I have also included warnings in the
descriptions of the sub-pixel package release on SqueakMap.

Just a heads-up
Cheers,
Andy
