EmbeddedFont

Overview

EmbeddedFont is a class in Aspose.PDF FOSS for TypeScript.

An opaque handle to a font program registered with {@link Document.AddFont}.

This class declares 7 methods for EmbeddedFont objects in TypeScript programs. Available methods include: constructor, driver, encode, measure, measureShaped, probe, shapeRuns. All public members are accessible to any TypeScript application after installing the Aspose.PDF FOSS for TypeScript package. Properties: objNum, sfnt, shape, toUnicode, usedGids.

Properties

Name	Type	Access	Description
`sfnt`	`: SfntFont`	Read	@internal parsed font program.
`usedGids`	``	Read	@internal original GIDs (= CIDs) drawn with this font, across all pages.
`objNum`	`: number \| undefined`	Read/Write	@internal object number of the Type0 font dict, reserved on first draw and filled by the document’s finalize pass at Save (undefined until then).
`shape`	``	Read/Write	@internal default shaping flag, from {@link Document.AddFont}({ shape }).
`toUnicode`	``	Read	@internal gid → source text, for /ToUnicode of shaped/ligated/RTL glyphs.

Methods

Signature	Description
`constructor(sfnt: SfntFont)`	@internal Construct via {@link Document.AddFont}.
`measure(text: string, fontSize: number)` → `number`	@internal Width of `text` in points at `fontSize`; chars absent from the font’s cmap are dropped (no recording).
`encode(text: string)` → `Uint8Array`	@internal Encode `text` to 2-byte Identity-H glyph codes (CID = original GID), recording each used GID for subsetting.
`probe(text: string)` → `number`	@internal Count of cmappable chars in `text`, without recording glyphs.
`driver()` → `FontDriver`	@internal A {@link FontDriver} view for the layout/stamping engine.
`shapeRuns(text: string, opts: ShapeOpts)` → `ShapedRun[]`	@internal Shape `text` into visual runs, recording used gids and, for each final gid, the source code points of its cluster (for /ToUnicode).
`measureShaped(text: string, fontSize: number, opts: ShapeOpts)` → `number`	@internal Shaped width of `text` in points at `fontSize`.
