Python PDF form flattening

Question

How do I "flatten" a PDF-form? I have a PDF form which needs to be filled. I have a simple example where TEMP_FORM.pdf is the from and data_dict is the value to be filled in TEMP_FORM.pdf. The output file is saved as FORM1.pdf but is still editable I need flatten that file so that the value cannot be edited. from PyPDF2 import PdfFileReader, PdfFileWriter TEMPLATE_PATH = 'TEMP_FORM.pdf' OUTPUT_PATH = 'FORM1.pdf' data_dict = { 'name': 'XYZ', 'address': 'PQR', 'email': '[email protected]', 'send_date': '2018-02-13', 'due_date': '2018-03-13' } if __name__ == '__main__': input_file = PdfFileReader(open(TEMPLATE_PATH, "rb")) output_file = PdfFileWriter() output_file.addPage(input_file.getPage(0)) output_file.updatePageFormFieldValues(output_file.getPage(0), data_dict) output_stream = open(OUTPUT_PATH, "wb") output_file.write(output_stream) output_stream.close() JavaScript questions and answers, JavaScript questions pdf, JavaScript question bank, JavaScript questions and answers pdf, mcq on JavaScript pdf, JavaScript questions and solutions, JavaScript mcq Test , Interview JavaScript questions, JavaScript Questions for Interview, JavaScript MCQ (Multiple Choice Questions)

Per the Adobe Docs, you can change the Bit Position of the Editable Form Fields to 1 to make them ReadOnly. I provided a full solution here, but it uses Django: https://stackoverflow.com/a/55301804/8382028 Adobe Docs (page 552): https://www.adobe.com/content/dam/acom/en/devnet/pdf/pdfs/pdf_reference_archives/PDFReference.pdf Use PyPDF2 to fill the fields, then loop through the annotations and do this: for j in range(0, len(output_file['/Annots'])): writer_annot = output_file['/Annots'][j].getObject() for field in data_dict: if writer_annot.get('/T') == field: writer_annot.update({ NameObject("/Ff"): NumberObject(1) # make ReadOnly })
