It was nice to get update on the patch for LCD filtering from SuSE builds shared by David Turner, one of the freetype2 upstream developers that means a lot for users to refer his concern about regarding the LCD filtering and the Cairo patch are all on a public.

[Touch-packages] [Bug 145604]
I am trying to enable subpixel rendering on poppler and I found my rendering result is suboptimal. After gdbing into cairo, I am surprise that cairo is still using the legacy filter as the "default". To the the situation even worse, cairo removed the interfaces to set the lcdfiler (cairo_font_options_set_lcd_filter) because "they are too specific to FreeType". Well, maybe that is true. But now how can I use the real Freetype default filter (FIR5) in the newest cairo without pathcing it? I think maybe manually set a FcPattern is OK but I really do not want to learn/invoke/rely Fontconfig just for setting a filter that should be default. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to cairo in Ubuntu. https://bugs.launchpad.net/bugs/145604 Title: VRGB sub-pixel hinting causes black-on-black text rendering Status in libcairo: Confirmed Status in cairo package in Ubuntu: Triaged Status in compiz package in Ubuntu: Invalid Status in compiz-fusion-plugins-main package in Ubuntu: Invalid Bug description: Binary package hint: libcairo2 There is a long-standing problem (Gutsy, Hardy, Intrepid - possibly Jaunty too) with sub-pixel rendering which affects metacity or compiz composition (see the images attached to this bug) when VRGB is chosen as the sub-pixel format.

Like some others, I also object to keeping the legacy filter as the default. Freetype doesn't call it legacy without reason: it is optimized for one special rendering preference, full native hinting (IMO it's doing badly even in that case), and is crap in all others. Moreover, if the fonts do not have high-quality hinting instructions, it does a bad job as well. I think this isn't even subjective, the color fringing of the legacy filter is bad regardless of display and/or personal preferences. If you still think it matters to not surprise users (I certainly would call improved text rendering a good surprise, though), the FIR3 filter might be a good choice for the default, but I'd surely go for the default (FIR5) by default. This is how it should be anyway. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to cairo in Ubuntu. https://bugs.launchpad.net/bugs/145604 Title: VRGB sub-pixel hinting causes black-on-black text rendering Status in libcairo - cairo vector graphics library: Confirmed Status in cairo package in Ubuntu: Triaged Status in compiz package in Ubuntu: Invalid Status in compiz-fusion-plugins-main package in Ubuntu: Invalid Bug description: Binary package hint: libcairo2 There is a long-standing problem (Gutsy, Hardy, Intrepid - possibly Jaunty too) with sub-pixel rendering which affects metacity or compiz composition (see the images attached to this bug) when VRGB is chosen as the sub-pixel format.
