--- Comment #11 from V Stuart Foote <vstuart.fo...@utsa.edu> ---
Adjusting this to reflect state of HarfBuzz's handling of sm math formulas on
Windows builds. It provides a nice ODT sample document.
Also here are a few sample starmath formulas to check progress:
=-=
nroot{3}{27 over 2} cdot sqrt{9}
%ALPHA %PHI %OMEGA %alpha %phi %omega newline
%iALPHA %iPHI %iOMEGA %ialpha %iphi %iomega newline
oper %PHI from 1 to n x " " oper %iPHI from 1 to n x newline
sqrt{sum from 1 to n x} " " nroot{3}{prod from 1 to n x}
=-=
Please point newly arriving issues for math formula scaling and composition on
Windows here--with note to compare _both_ the OpenGL and default GDI+
rendering. Also to compare the new layout engine against the old DirectWrite
only text layout.
When/if bug 103680 to implement OpenType Math table features and a new internal
formula composition this should resolve. Until then...
=-QA Note-=
as originally opened against 5.1.4.2 (for VCL OpenGL glyph scaling) this
probably should have been resolved a duplicate of bug 99351, or even bug
32362--but have repurposed it.
