Leadtools 16.5 support the PDFFile?

Hello Guys,

does Leadtools 16.5 support the PDFFile? (see below examples)

if yes, how?

The following example will convert an existing PDF file to PDF/A:

             // Create a PDFFile object from the input PDF file
             PDFFile inputFile = new PDFFile("Input.pdf");
             // Convert it to PDF/A
             inputFile.ConvertToPDFA("OutputPDFA.pdf");
             

This example will merge 4 PDF files:

             // Create a PDFFile object from the first PDF file
             PDFFile firstFile = new PDFFile("1.pdf");
             // Merge it with the second, third and forth files
             firstFile.MergeWith(new string[] { "2.pdf", "3.pdf", "4.pdf" }, "Output.pdf");
