Description Brion Vibber 2011-11-28 22:45:29 UTC
We currently render math images only for traditional screen resolution; on high-density screens (eg iPhone 4) and when printing, these can look blurry or blocky.

Rendering another PNG at 2.0x the size would be suitable for iPhone & iPod Touch Retina display, Samsung Nexus Galaxy, and printing.

1.5x would be suitable for many phones running at an intermediate 240dpi-ish resolution (Droid, Nexus 1, all Windows Phone 7 phones, etc).

Comment 2 Brion Vibber 2011-11-30 01:50:54 UTC
Dropping this idea in favor of MathJax, which produces fully client-scalable HTML or MathML (bug 31406).
Comment 3 Brion Vibber 2013-04-22 22:29:54 UTC
Reopening this; MathJax has some issues with printing and compatibility, so we might end up going with the higher-res rasters for default behavior.
Comment 4 Peter Krautzberger 2013-04-30 15:05:17 UTC
Brion, could you provide more information about these issues on the MathJax bug tracker?

Comment 5 Jarry1250 2013-10-02 20:36:53 UTC
Presumably we should either push ahead with this or make MathJax the default?
Comment 6 physikerwelt 2014-10-19 22:30:34 UTC
We have MathML and SVG now. This should solve the problem.
