Convert PDF/A to PDF

Convert PDF/A document to PDF means removing PDF/A restriction from the original document. Class Document has method RemovePdfaCompliance(..) to remove the PDF compliance information from input/source file.

    public void convertPDFAtoPDF() {
        String pdfaDocumentFileName = new File(fileStorage, "Conversion/sample-pdfa.pdf").toString();
        String pdfDocumentFileName = new File(fileStorage, "Conversion/sample-out.pdf").toString();

        try {
            // Create Document object
            document = new Document(pdfaDocumentFileName);

            // Remove PDF/A compliance information
            document.removePdfaCompliance();

            // Save output in XML format
            document.save(pdfDocumentFileName);
        } catch (Exception e) {
            resultMessage.setText(e.getMessage());
            return;
        }
        resultMessage.setText(R.string.success_message);

    }

This info also removes if you make any changes in the document (e.g. add pages). In the following example, the output document loses PDF/A compliance after the page adding.

   public void convertPDFAtoPDFAdvanced() {
        String pdfaDocumentFileName = new File(fileStorage, "Conversion/sample-pdfa.pdf").toString();
        String pdfDocumentFileName = new File(fileStorage, "Conversion/sample-out.pdf").toString();

        // Create Document object
        document = new Document(pdfaDocumentFileName);

        // Adding a new (empty) page removes PDF/A compliance information.
        document.getPages().add();

        // Save updated document
        document.save(pdfDocumentFileName);
    }
