`pdfSetTextExtractionWordGap`

Set the horizontal gap threshold (in text-space units) above

Category	Text extraction tuning

Purpose — Set the horizontal gap threshold (in text-space units) above which the text-extraction routines insert a space between two adjacent runs that don't already have one.

Description — Consumed by the run-to-text assembler (RunsToText) used by the extraction APIs; confirmed live (not a stored-only field) by tracing its two call sites in the extraction path.

Declarations

int32_t __stdcall pdfSetTextExtractionWordGap(PPDF IPDF, double NewWordGap);

Delphi

function pdfSetTextExtractionWordGap(const IPDF: PPDF; NewWordGap: Double): Integer; stdcall; external 'LumasPdf.dll';

Parameters

Parameter	Type	Description
`IPDF`	`PPDF`	Instance handle.
`NewWordGap`	`Double`	Gap threshold in text-space units above which a synthetic space is inserted between runs during extraction.

Return value — 1 on a valid handle; 0 on an invalid handle.
