Output file:

	// create empty pdf document
	outputDoc = MakeObject<Document>();

	// read pdf file to Aspose Document
	System::SharedPtr<Document> firstDoc = MakeObject<Document>(u"1.pdf");
	secondDoc = MakeObject<Document>(u"2.pdf");

	// add page from one document to another directly
	for (auto const& page : firstDoc->get_Pages())
	for (auto const& page : secondDoc->get_Pages())

	// save document as specific pdf standard PDFA 3Y
	// delete objects that impossible to convert
	outputDoc->Convert(u"Merger_pdf_pdfa.pdf", PdfFormat::PDF_A_3U, ConvertErrorAction::Delete);
