pub struct TtfParser<'a> { /* private fields */ }

TrueType font parser.

Parses the font directory and individual tables from raw TTF data. Does not own the font data; operates on borrowed slices.

Implementations

impl<'a> TtfParser<'a>

pub fn new(data: &'a [u8]) -> Result<Self, FontError>

Create a new parser from raw TTF data.

pub fn find_table(&self, tag: TableTag) -> Option<TableEntry>

Find a table by tag.

pub fn table_data(&self, entry: &TableEntry) -> Result<&'a [u8], FontError>

Get the raw bytes for a table.

pub fn parse_head(&self) -> Result<HeadTable, FontError>

Parse the head table.

pub fn parse_hhea(&self) -> Result<HheaTable, FontError>

Parse the hhea table.

pub fn parse_maxp(&self) -> Result<MaxpTable, FontError>

pub fn char_to_glyph(&self, ch: u32) -> Result<u16, FontError>

Look up a glyph index from a character code using cmap table. Supports format 4 (BMP) cmap subtable.

pub fn glyph_offset( &self, glyph_id: u16, head: &HeadTable, ) -> Result<(u32, u32), FontError>

Get glyph offset from loca table.

pub fn parse_glyph(&self, glyph_id: u16) -> Result<GlyphOutline, FontError>
