ExportPDFOperation Word Format Retain Page Layout and Retain Flowing Text

[LL123L]

In the desktop Acrobat DC, the Export to Word function can create both Retain Flowing Text (RFT)and Retain Page Layout (RPL) formatted Word.docx files.

The Github .Net example, ExportPDFToDocx, exports PDF to Word.

What is the parameter for  RFT or RPL  output format?

// Set operation input from a local PDF file
FileRef sourceFileRef = FileRef.CreateFromLocalFile(@"exportPdfInput.pdf");
exportPdfOperation.SetInput(sourceFileRef);

// Execute the operation.
FileRef result = exportPdfOperation.Execute(executionContext);

Thanks for the help.
