Struct GlyphZone 

pub struct GlyphZone<'a, C: PointCoord> {
    pub glyph: GlyphId,
    pub bytecode: &'a [u8],
    pub points: &'a mut [Point<C>],
    pub unscaled: &'a mut [Point<i32>],
    pub flags: &'a mut [PointFlags],
    pub contours: &'a [u16],
    pub phantom: &'a mut [Point<C>; 4],
    pub is_composite: bool,
    pub coords: &'a [F2Dot14],
}

The points a Hinter works on, zone 1 in the specification’s terms.

Unlike OutlineRef this is mutable, stores its phantom points alongside the rest, and is not shifted by the left side bearing.

Fields

glyph: GlyphId

The glyph being hinted.

bytecode: &'a [u8]

The glyph’s TrueType instructions.

points: &'a mut [Point<C>]

Scaled points, including phantom points, which hinting moves.

unscaled: &'a mut [Point<i32>]

The same points in font units.

flags: &'a mut [PointFlags]

The flag for each point, which hinting also marks up.

contours: &'a [u16]

Contour end points, relative to the start of points.

phantom: &'a mut [Point<C>; 4]

The four phantom points, which hinting may move.

is_composite: bool

True when hinting a composite rather than a simple glyph.

coords: &'a [F2Dot14]

Normalized variation coordinates, empty for a static instance.
