ot_math_get_glyph_assembly

Description:

[ Version ( since = "1.3.3" ) ]
public uint ot_math_get_glyph_assembly (Font font, Codepoint glyph, Direction direction, uint start_offset, out unowned OtMathGlypthPart[] parts, out Position italics_correction)

Fetches the GlyphAssembly for the specified font, glyph index, and direction.

Returned are a list of OtMathGlypthPart 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 Direction values are accepted, only the result of HB_DIRECTION_IS_HORIZONTAL is considered.</note>

Parameters:

font	Font to work upon
glyph	The index of the glyph to stretch
direction	direction of the stretching (horizontal or vertical)
start_offset	offset of the first glyph part to retrieve
parts	the glyph parts returned
italics_correction	italics correction of the glyph assembly
parts_count	Input = maximum number of glyph parts to return; Output = actual number of parts returned

Returns:

the total number of parts in the glyph assembly
