Method TryComputeControlBounds
TryComputeControlBounds(out GlyphBoundingBox)
Computes the control-point bounding box: the box containing every on-curve and
off-curve point. This is the box glyf's header records for straight-edged
glyphs, and a superset of the true curve box wherever a control point lies outside it.
Integer only — no scaling, no root finding.
public bool TryComputeControlBounds(out GlyphBoundingBox boundingBox)
Parameters
boundingBoxGlyphBoundingBoxThe control-point box when the glyph has at least one point.
