pdfGetTextScaling

Purpose — Read the current horizontal text scaling (PDF Tz operand).

Declarations

double __stdcall pdfGetTextScaling(PPDF IPDF);

function pdfGetTextScaling(const IPDF: PPDF): Double; stdcall; external 'LumasPdf.dll';

Return value — Current scaling as a percentage (PDF default 100); the engine does not itself default this to 100 internally at document creation — it returns whatever FTextScaling's zero-value default is until first set, so check pdfSetTextScaling if you rely on the PDF-spec default explicitly.
