`pdfRestoreGraphicState`

Emit a Q (restore graphics state) operator and pop the

BOOL32 __stdcall pdfRestoreGraphicState(PPDF IPDF);

Delphi

function pdfRestoreGraphicState(const IPDF: PPDF): LongBool; stdcall;

Purpose. Emit a Q (restore graphics state) operator and pop the tracked CTM stack — the counterpart of pdfSaveGraphicState (Document Info & Structure Tree).

Description. Both pdfSaveGraphicState/pdfRestoreGraphicState are real: they write the actual q/Q content-stream operators and maintain a parallel internal CTM stack (PushCTM/PopCTM) so that pdfGetMatrix (Coordinate Transform and Matrix) correctly reflects the restored transform after a Q, not just the PDF viewer's own state.

Return value. True if there is a current content stream; False otherwise.
