Struct CidFontMetrics 

pub struct CidFontMetrics { /* private fields */ }

Font metrics for a CID font, handling the /W array and /DW default width.

CID fonts use a different width specification than simple fonts:

• /DW: default width for all CIDs (default 1000)
• /W: array of width overrides in the format: [CID [w1 w2 ...] CIDstart CIDend w ...]

Implementations

impl CidFontMetrics

pub fn new( widths: HashMap<u32, f64>, default_width: f64, ascent: f64, descent: f64, font_bbox: Option<[f64; 4]>, font_type: CidFontType, cid_to_gid: CidToGidMap, system_info: Option<CidSystemInfo>, ) -> Self

Create CidFontMetrics from parsed values.

pub fn default_metrics() -> Self

Create default CidFontMetrics.

pub fn get_width(&self, cid: u32) -> f64

Get the width for a CID in glyph space (1/1000 of text space).

pub fn ascent(&self) -> f64

Font ascent in glyph space units.

pub fn descent(&self) -> f64

Font descent in glyph space units.

pub fn font_bbox(&self) -> Option<[f64; 4]>

Font bounding box.

pub fn default_width(&self) -> f64

Default width for CIDs not in the width overrides.

pub fn font_type(&self) -> CidFontType

CID font subtype.

pub fn cid_to_gid(&self) -> &CidToGidMap

CID-to-GID mapping.

pub fn map_cid_to_gid(&self, cid: u32) -> u32

Map a CID to a GID.

pub fn system_info(&self) -> Option<&CidSystemInfo>

CID system information.
