Overview

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

This class declares 6 methods for TextFont objects in TypeScript programs. Available methods include: constructor, decode, decodeGlyphs, decodeRun, encode, encodeChar. All public members are accessible to any TypeScript application after installing the Aspose.PDF FOSS for TypeScript package. Properties: bold, canEncode, cid, code, codeWidth, italic, and 4 more.

Properties

Name	Type	Access	Description
`codeWidth`	`: number`	Read	The narrowest character code this font admits, in bytes: 1 for a simple font, 2 for Identity-H and most composite fonts.
`wmode`	`: 0 \| 1`	Read	Writing mode from the `/Encoding` CMap: 0 horizontal, 1 vertical.
`name`	`: string`	Read	The font’s /BaseFont name (subset prefix preserved), or undefined if absent.
`bold`	`: boolean`	Read	True when the document declares this font bold / italic.
`italic`	`: boolean`	Read	Gets the italic.
`type3`	`: Type3Data`	Read	Set for a Type 3 font: its glyph procedures and the space they draw in.
`code`	`: number`	Read	Gets the code.

`len`	`: number`	Read	Gets the len.
`canEncode`	`boolean`	Read	Gets the can encode.

Methods

Signature	Description
`constructor(dict: PdfDict, resolve: Resolve, inflate: Inflate)`	Calls constructor(dict, resolve, inflate) on this TextFont instance.
`decodeRun(bytes: Uint8Array)` → `RunMetrics`	Decode bytes into text plus the run’s advance metrics.
`decode(bytes: Uint8Array)` → `string`	Decode a show-string’s bytes into Unicode text.
`encodeChar(ch: string)` → `number \| undefined`	Map one Unicode character to its 1-byte code in this font’s encoding, or `undefined` if the font cannot represent it.
`encode(text: string)` → `Uint8Array`	Encode `text` to show-string bytes in this font’s encoding.
`decodeGlyphs(bytes: Uint8Array)` → `Glyph[]`	Decode bytes into one record per character code (positions, em-widths).
