pub struct CompositeGlyphFlag { /* fields omitted */ }

Implementations

impl CompositeGlyphFlag

pub const ARG_1_AND_2_ARE_WORDS: CompositeGlyphFlag

Bit 0: If this is set, the arguments are 16-bit (uint16 or int16); otherwise, they are bytes (uint8 or int8).

pub const ARGS_ARE_XY_VALUES: CompositeGlyphFlag

Bit 1: If this is set, the arguments are signed xy values; otherwise, they are unsigned point numbers.

pub const ROUND_XY_TO_GRID: CompositeGlyphFlag

Bit 2: For the xy values if the preceding is true.

pub const WE_HAVE_A_SCALE: CompositeGlyphFlag

Bit 3: This indicates that there is a simple scale for the component. Otherwise, scale = 1.0.

pub const MORE_COMPONENTS: CompositeGlyphFlag

Bit 4: Reserved, set to 0 Bit 5: Indicates at least one more glyph after this one.

pub const WE_HAVE_AN_X_AND_Y_SCALE: CompositeGlyphFlag

Bit 6: The x direction will use a different scale from the y direction.

pub const WE_HAVE_A_TWO_BY_TWO: CompositeGlyphFlag

Bit 7: There is a 2 by 2 transformation that will be used to scale the component.

pub const WE_HAVE_INSTRUCTIONS: CompositeGlyphFlag

Bit 8: Following the last component are instructions for the composite character.

pub const USE_MY_METRICS: CompositeGlyphFlag

Bit 9: If set, this forces the aw and lsb (and rsb) for the composite to be equal to those from this original glyph. This works for hinted and unhinted characters.

pub const OVERLAP_COMPOUND: CompositeGlyphFlag

Bit 10: If set, the components of the compound glyph overlap.

Use of this flag is not required in OpenType — that is, it is valid to have components overlap without having this flag set. It may affect behaviors in some platforms, however. (See Apple’s specification for details regarding behavior in Apple platforms.) When used, it must be set on the flag word for the first component. See additional remarks, above, for the similar OVERLAP_SIMPLE flag used in simple-glyph descriptions.

pub const SCALED_COMPONENT_OFFSET: CompositeGlyphFlag

Bit 11: The composite is designed to have the component offset scaled.

pub const UNSCALED_COMPONENT_OFFSET: CompositeGlyphFlag

Bit 12: The composite is designed not to have the component offset scaled.

pub const fn empty() -> CompositeGlyphFlag

Returns an empty set of flags

pub const fn all() -> CompositeGlyphFlag

pub const fn bits(&self) -> u16

pub fn from_bits(bits: u16) -> Option<CompositeGlyphFlag>

pub const fn from_bits_truncate(bits: u16) -> CompositeGlyphFlag

Convert from underlying bit representation, dropping any bits that do not correspond to flags.

pub const unsafe fn from_bits_unchecked(bits: u16) -> CompositeGlyphFlag

Convert from underlying bit representation, preserving all bits (even those not corresponding to a defined flag).

pub const fn is_empty(&self) -> bool

Returns true if no flags are currently stored.

pub const fn is_all(&self) -> bool

Returns true if all flags are currently set.

pub const fn intersects(&self, other: CompositeGlyphFlag) -> bool

Returns true if there are flags common to both self and other.

pub const fn contains(&self, other: CompositeGlyphFlag) -> bool

Returns true all of the flags in other are contained within self.

pub fn insert(&mut self, other: CompositeGlyphFlag)

Inserts the specified flags in-place.

pub fn remove(&mut self, other: CompositeGlyphFlag)

Removes the specified flags in-place.

pub fn toggle(&mut self, other: CompositeGlyphFlag)

Toggles the specified flags in-place.

pub fn set(&mut self, other: CompositeGlyphFlag, value: bool)

Inserts or removes the specified flags depending on the passed value.
