Implementations

impl PdfFont

pub fn glyph_path(&self, char_code: u8) -> Option<PsPath>

Get glyph outline path for a character code (single-byte fonts). Returns None for Type 3 fonts (they use content streams, not outlines).

pub fn glyph_path_cid(&self, cid: u16) -> Option<PsPath>

Get glyph outline path for a CID (2-byte composite fonts).

pub fn glyph_path_unicode(&self, unicode: u16) -> Option<PsPath>

Get glyph path for a Unicode code point, bypassing CID machinery. Used for malformed PDFs that mix WinAnsi literal strings in CID fonts.

pub fn glyph_width_unicode(&self, unicode: u16) -> f64

Get width for a Unicode code point from hmtx, bypassing CID widths.

pub fn glyph_width(&self, char_code: u8) -> f64

Get width for a character code (in text space units, already ÷1000).

pub fn glyph_width_cid(&self, cid: u16) -> f64

Get width for a CID (2-byte composite fonts).

pub fn font_matrix(&self) -> Matrix

Font matrix (glyph space → text space).

Returns identity for CidCff because the full matrix (including per-FD composition) is applied inside glyph_path_cid().

pub fn is_composite(&self) -> bool

Whether this is a composite (CID) font that uses multi-byte character codes.

pub fn wmode(&self) -> u8

Writing mode: 0 = horizontal, 1 = vertical.

pub fn dw2(&self) -> [f64; 2]

Default vertical metrics [v_y, w1] for vertical writing mode. v_y = vertical origin y offset (in 1/1000 em), w1 = vertical advance.

pub fn vertical_metrics_cid(&self, cid: u16) -> [f64; 3]

Get per-CID vertical metrics (w1, v_x, v_y), falling back to DW2. Returns values in 1/1000 em units.

pub fn has_cid_glyph(&self, cid: u16) -> bool

Whether a CID maps to a GID that exists in the font. Used to distinguish valid 2-byte CID codes from misinterpreted WinAnsi bytes in malformed PDFs that mix 1-byte literal text with CID fonts.

pub fn resolve_code_to_cid(&self, code: u32) -> u32

Map a raw character code to a CID using the encoding CMap. Returns the code unchanged if no mapping exists (identity encoding).

pub fn code_width(&self, first_byte: u8) -> usize

Get the byte width of a character code starting with the given byte. Only meaningful for composite fonts; returns 1 for simple fonts.

pub fn is_type3(&self) -> bool

Whether this is a Type 3 font (glyphs are content streams).

pub fn type3_char_proc(&self, char_code: u8) -> Option<&[u8]>

Get the Type 3 glyph stream data for a character code.

pub fn type3_resources(&self) -> Option<&PdfDict>

Get the Type 3 font resources dict.
