`pdfGetFontEx`

Read basic font-descriptor metrics (ascent/descent/cap-height,

Category	Font introspection
Note	TrueType fonts only (see Remarks)

Purpose — Read basic font-descriptor metrics (ascent/descent/cap-height, em-scaled) and the base font name for a registered font.

Declarations

BOOL32 __stdcall pdfGetFontEx(PPDF IPDF, uint32_t Handle, TPDFFontObj* F);

Delphi

function pdfGetFontEx(const IPDF: PPDF; Handle: Cardinal; var F: TPDFFontObj): LongBool; stdcall; external 'LumasPdf.dll';

Parameters

Parameter	Type	Description
`IPDF`	`PPDF`	Instance handle.
`Handle`	`Cardinal`	Font handle.
`F`	`TPDFFontObj*`	Receives `Ascent`/`Descent`/`CapHeight` (normalized to em-space, `/UnitsPerEm` defaulting to `1000` if the font doesn't declare one) and `BaseFont` (PostScript name, or family name if no PostScript name is present).

Return value — TRUE only if Handle resolves to a TrueType font entry; FALSE for standard-14, Type 1, or CID-predefined fonts — this call has no data source for those kinds.

Remarks — For a kind-agnostic info query (works for any font kind, with heuristic style detection), use pdfGetFontInfoEx instead.
