Example C++: this sample code shows PDF to PDFA concatenation
Input file:
File not added
File not added
Output format:
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())
outputDoc->get_Pages()->CopyPage(page);
for (auto const& page : secondDoc->get_Pages())
outputDoc->get_Pages()->CopyPage(page);
// 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);
