Actually, the system installation may be a bit more clever. We can detect the monitor at the installation time, and it'd be possible to know whether the subpixel rendering is enabled or not.
Sounds sensible.
Of course, this is apart from the patent issues. I don't know whether the subpixel patent was expired.
[Wearing the FreeType maintainer hat] Subpixel positioning of glyphs is not patented. The special handling of TrueType bytecode instructions for ClearType isn't patented either. However, Microsoft has patented a certain colour filter for ClearType to display fonts on LCD screens, which can be easily circumvented by using a slightly different colour filter. AFAIK, X11 already does that.
So, with this hat on, you would confirm the current subpixel rendring in freetype is OK to use as default? Or any underlying issues? This is the substantial information for the decision, I believe. thanks, Takashi -- To unsubscribe, e-mail: opensuse-factory+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-factory+owner@opensuse.org
