pdfrw

问题 So I'm trying to mark checkboxes in a PDF file with pdfrw. That means changing the checkboxes "AS" value from the default "/Off" to "/Yes". pdfrw is currently forcing parentheses around my "/Yes" when it writes to file, so it doesn't work. How do I keep it from adding these parentheses? My code: template_pdf = pdfrw.PdfReader(input_pdf_path) annotations = template_pdf.pages[0][/Annots] for annotation in annotations: annotation.update(pdfrw.PdfDict(AS="/Yes")) pdfrw.PdfWriter().write(output

问题 What I am trying to do is basically: Get PDF from URL Modify it via pdfrw Store it in memory as a BytesIO obj Upload it into a Django FileField via Model.objects.create(form=pdf_file, name="Some name") My issue is that when the create() method runs, it saves all of the fields except for the form . helpers.py import io import tempfile from contextlib import contextmanager import requests import pdfrw @contextmanager def as_file(url): with tempfile.NamedTemporaryFile(suffix='.pdf') as tfile:

问题 I'm trying to automate merging several PDF files and have two requirements: a) existing bookmarks AND b) pagelabels (custom page numbering) need to be retained. Retaining bookmarks when merging happens by default with PyPDF2 and pdftk, but not with pdfrw. Pagelabels are consistently not retained in PyPDF2, pdftk or pdfrw. I am guessing, after having searched a lot, that there is no straightforward approach to doing what I want. If I'm wrong then I hope someone can point to this easy solution.

问题 I'm trying to read in an example PDF with PDFrw. The PDF contains the phrase Hello Matthew in the bottom left corner at coordinates (100, 100) . When I attempt to output the text (if I even can?) I get a stream of data. I can't seem to figure out how to get that as text. >>> import pdfrw >>> file_object = pdfrw.PdfReader("Hello.pdf") >>> file_object {'/ID': ['<f643bc0910dfb67725d53e11054f4609>', '<f643bc0910dfb67725d53e11054f4609>'], '/Info': (5, 0), '/Root': {'/Outl ines': (8, 0), '/PageMode

问题 Using the code below, I am trying to import a pdf page into an existing canvas object and save to PDF. This usually works just fine, but I noticed that when I try it with a PDF generated from a scanned document, it results in a blank page. Any takers? from reportlab.pdfgen import canvas from pdfrw import PdfReader from pdfrw.buildxobj import pagexobj from pdfrw.toreportlab import makerl c = canvas.Canvas(Out_Folder+pdf_file_name) c.setPageSize([11*inch, 8.5*inch]) page = PdfReader(folder+'2
