    data: TableDataRef<'a, MathGlyphInfoFixedHeader>,
}

MathGlyphInfo

Fields

data: TableDataRef<'a, MathGlyphInfoFixedHeader>

Implementations

impl<'a> MathGlyphInfo<'a>

pub const MIN_SIZE: usize

pub fn resolve_offset<O: Offset, R: FontRead<'a, Args = ()>>( &self, offset: O, ) -> Result<R, ReadError>

Resolve the provided offset from the start of this table.

pub fn offset_data(&self) -> FontData<'a>

Return a reference to this table’s raw data.

We use this in the compile crate to resolve offsets.

pub fn shape(&self) -> &Self

👎Deprecated:

just use the base type directly

Return a reference to the table’s ‘Shape’ struct.

This is a low level implementation detail, but it can be useful in some cases where you want to know things about a table’s layout, such as the byte offsets of specific fields.

pub fn math_italics_correction_info_offset(&self) -> Nullable<Offset16>

Offset to MathItalicsCorrectionInfo table, from the beginning of the MathGlyphInfo table. May be NULL.

pub fn math_italics_correction_info( &self, ) -> Option<Result<MathItalicsCorrectionInfo<'a>, ReadError>>

Attempt to resolve math_italics_correction_info_offset.

pub fn math_top_accent_attachment_offset(&self) -> Nullable<Offset16>

Offset to MathTopAccentAttachment table, from the beginning of the MathGlyphInfo table. May be NULL.

pub fn math_top_accent_attachment( &self, ) -> Option<Result<MathTopAccentAttachment<'a>, ReadError>>

Attempt to resolve math_top_accent_attachment_offset.

pub fn extended_shape_coverage_offset(&self) -> Nullable<Offset16>

Offset to the Coverage table for glyphs with extended shapes, from the beginning of the MathGlyphInfo table. May be NULL.

pub fn extended_shape_coverage( &self, ) -> Option<Result<CoverageTable<'a>, ReadError>>

Attempt to resolve extended_shape_coverage_offset.

pub fn math_kern_info_offset(&self) -> Nullable<Offset16>

Offset to the MathKernInfo table, from the beginning of the MathGlyphInfo table. May be NULL.

pub fn math_kern_info(&self) -> Option<Result<MathKernInfo<'a>, ReadError>>

Attempt to resolve math_kern_info_offset.

pub fn math_italics_correction_info_offset_byte_range(&self) -> Range<usize>

pub fn math_top_accent_attachment_offset_byte_range(&self) -> Range<usize>

pub fn extended_shape_coverage_offset_byte_range(&self) -> Range<usize>

pub fn math_kern_info_offset_byte_range(&self) -> Range<usize>

impl MathGlyphInfo<'_>

pub fn is_extended_shape(&self, glyph: GlyphId) -> bool

Whether a glyph is an extended shape: one tall enough that a following script is positioned against its own height rather than the font’s.
