otMathGetGlyphAssembly

Fetches the GlyphAssembly for the specified font, glyph index, and direction. Returned are a list of #hb_ot_math_glyph_part_t glyph parts that can be used to draw the glyph and an italics-correction value (if one is defined in the font).

<note>The direction parameter is only used to select between horizontal or vertical directions for the construction. Even though all #hb_direction_t values are accepted, only the result of #HB_DIRECTION_IS_HORIZONTAL is considered.</note>
