Struct read_fonts::tables::glyf::PointFlags

pub struct PointFlags(/* private fields */);

Flags describing the properties of a point.

Some properties, such as on- and off-curve flags are intrinsic to the point itself. Others, designated as markers are set and cleared while an outline is being transformed during variation application and hinting.

Implementations

impl PointFlags

pub const fn on_curve() -> Self

Creates a new on curve point flag.

pub const fn off_curve_quad() -> Self

Creates a new off curve quadratic point flag.

pub const fn off_curve_cubic() -> Self

Creates a new off curve cubic point flag.

pub const fn from_bits(bits: u8) -> Self

Creates a point flag from the given bits. These are truncated to ignore markers.

pub const fn is_on_curve(self) -> bool

Returns true if this is an on curve point.

pub const fn is_off_curve_quad(self) -> bool

Returns true if this is an off curve quadratic point.

pub const fn is_off_curve_cubic(self) -> bool

Returns true if this is an off curve cubic point.

pub const fn is_off_curve(self) -> bool

pub fn flip_on_curve(&mut self)

Flips the state of the on curve flag.

This is used for the TrueType FLIPPT instruction.

pub fn set_on_curve(&mut self)

Enables the on curve flag.

This is used for the TrueType FLIPRGON instruction.

pub fn clear_on_curve(&mut self)

Disables the on curve flag.

This is used for the TrueType FLIPRGOFF instruction.

pub fn has_marker(self, marker: PointMarker) -> bool

Returns true if the given marker is set for this point.

pub fn set_marker(&mut self, marker: PointMarker)

Applies the given marker to this point.

pub fn clear_marker(&mut self, marker: PointMarker)

Clears the given marker for this point.

pub const fn without_markers(self) -> Self

Returns a copy with all markers cleared.

pub const fn to_bits(self) -> u8

Returns the underlying bits.

Trait Implementations

impl Clone for PointFlags

fn clone(&self) -> PointFlags

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for PointFlags

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for PointFlags

fn default() -> PointFlags

Returns the “default value” for a type.

impl PartialEq for PointFlags

fn eq(&self, other: &PointFlags) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl Zeroable for PointFlags

fn zeroed() -> Self

Calls zeroed.

impl AnyBitPattern for PointFlags

impl Copy for PointFlags

impl Eq for PointFlags

impl NoUninit for PointFlags
