CompareFileVisualsA

Document comparison, DLL

Description

Compares the current document with a PDF file visually through the DLL narrow-string convention, returning the same JSON report as CompareFileVisuals

Syntax

Function DLCompareFileVisualsA(InstanceID: Integer; OtherFileName, Password: PAnsiChar; DPI: Double; ColorTolerance: Integer): PAnsiChar; Stdcall;

Return values
