`fntGetFont`

Read basic metrics (ascent/descent/cap-height, em-normalized

Category	Font-object introspection

Purpose — Read basic metrics (ascent/descent/cap-height, em-normalized to 1000 units) and base font name from a PFNT snapshot.

Declarations

BOOL32 __stdcall fntGetFont(PFNT IFont, TPDFFontObj* F);

Delphi

function fntGetFont(const IFont: PFNT; var F: TPDFFontObj): LongBool; stdcall; external 'LumasPdf.dll';

Parameters

Parameter	Type	Description
`IFont`	`PFNT`	Snapshot handle.
`F`	`TPDFFontObj*`	Receives the metrics.

Return value — TRUE on success; FALSE if IFont is NULL or the snapshot's UnitsPerEm is <= 0 (degenerate/unavailable metrics).
