403494 - XFT based font engine required for fast fonts rendering

Status: RESOLVED WONTFIX

(Core :: Graphics, enhancement)

Description

[Oleg Romashin (:romaxa)]

After landing Bug 362682, Xft based font metrics has been killed from gfxPangoFonts.h (gfxPangoFontGroup::CreateGlyphRunsXft/Fast).

I think it would be better allow to use Xft based font metrics generation for Mobile devices...

Some change from bug 362682:
.........
- XftGlyphExtents(dpy, xfont, &glyph, 1, &info);
+ pango_font_get_glyph_extents (pangofont, glyph, NULL, &rect);
.........
made font metrics generation ~1.5-2x slower... (visible on zooming see Bug 402555)

Would it not be more useful to file a bug on pango with a reproducible testcase?

Comment 3

[Benoit Girard (:BenWa)]

This bug hasn't been touched in years. Is this still wanted?

Comment 4

[Oleg Romashin (:romaxa)]

No, I guess pango/ft2 font engines are optimized good enough already and no need for this anymore.
