Description Joe Wright 2016-01-28 15:39:56 UTC
Description of problem:
Customer would like for us to to enable subpixel rendering by default.

It looks like the changelog for freetype indicates that this SHOULD be happening.
~~~
* Tue Jul 31 2007 Behdad Esfahbod <besfahbo> 2.3.5-2
  - Change spec file to permit enabling bytecode-interpreter and
    subpixel-rendering without editing spec file.
  - Resolves: 249986
~~~

But their users claim that we're not enabling by default when we build it.

--with subpixel rendering is not being set.


But, maybe the flag is being passed but the spec file isn't reflecting it?

The patents on subpixel rendering owned by Microsoft are still valid and should expire in 2019-10-07 (according to Wikipedia - https://en.wikipedia.org/wiki/Subpixel_rendering):

http://www.google.com/patents?vid=USPAT6219025
http://www.google.com/patents?vid=USPAT6239783
http://www.google.com/patents?vid=USPAT6307566

http://www.google.com/patents?vid=USPAT6243070

http://www.google.com/patents?vid=USPAT6282327
http://www.google.com/patents?vid=USPAT6624828

Looking at the individual patents you can see that Microsoft still pays maintenance fees.

I'm closing this with resolution cantfix.
