`pdfGetGlyphIndex`

Map a Unicode code point to its glyph ID in the currently

Category	Glyph introspection
Note	current font only, TrueType only (see Remarks)

Purpose — Map a Unicode code point to its glyph ID in the currently active font.

Declarations

int32_t __stdcall pdfGetGlyphIndex(PPDF IPDF, uint32_t Index);

Delphi

function pdfGetGlyphIndex(const IPDF: PPDF; Index: Cardinal): Integer; stdcall; external 'LumasPdf.dll';

Parameters

Parameter	Type	Description
`IPDF`	`PPDF`	Instance handle.
`Index`	`Cardinal`	A Unicode code point (despite the parameter name, this is a character code, not a glyph index — the glyph index is what's returned).

Return value — Glyph ID (> 0) if the currently active font is TrueType and has that glyph; 0 if the current font isn't TrueType or the character has no glyph.

Remarks — no font-handle parameter. There is no way to query a glyph index for a font other than whichever one is currently active — switch fonts first via pdfChangeFont if you need a different font's mapping.
