I am seeking assistance in generating the Base64 representation of a PDF file that I intend to print. The goal is to merge an image into this PDF using PyPDF2. I have successfully managed to merge images into PDFs, but I need guidance on obtaining the Base64 representation of the existing PDF file so that I can include it in my project.

is it possible if somehow i could get base64 of  report which i am printing using _get_report_values  and return my modified pdf ?

I did this in v16 with something like this:

report = self.env.ref('stock.action_report_delivery')
pdf_content, dummy = self.env['ir.actions.report'].sudo().with_context(lang=self.partner_id.lang)._render_qweb_pdf(report, self.id)

data = base64.encodebytes(pdf_content)


Hope it helps :)-

Hope this snippet helps 

from io import BytesIO
import base64

input_file = fields.Binary('File')
outputb64 = BytesIO(base64.b64decode(self.input_file)
