This is a plug-in for Glyphs app to edit OpenType MATH table data as well as generate MATH table when exporting font.
Go to Window → Plugin Manger and search for “OpenType MATH Plug-in” and install it.
Restart Glyphs and the plug-in should be ready (when the plug-in is updated, Glyphs should be restarted as well to use the new version).
Below is a quick reference for using the plug-in. For a more in depth documentation about building math fonts using this plug-in, see the Building OpenType math fonts article.
The plug-in adds some new menu entries:
math.ic
.
This anchor will be used to generate italic correction. Only the x-position
is effective, the y-position is ignored.math.ta
.
This anchor will be used to generate top accent position. Only the
x-position is effective, the y-position is ignored.math.tr
(top right), math.tl
(top left), math.br
(bottom right), math.bl
(bottom left). There can be
more than one anchor starting with each prefix (e.g. math.tr.1
,
math.tr.2
, etc) each describing one corner of the glyph.
Both x and y-position of the anchor are used to generate the math kerning
info.
If the font contains any MATH data, the plug-in will generate MATH table when the font is exported, no extra steps are needed.
