I like to test Python in different situations, it just makes my life easier in many situations. Python allows me to automate things that are normally repeated and boring, so I can focus on important aspects of my job. Today I will show you how can you edit PDF files with python.
In this example I will be using ReportLab.
The ReportLab Toolkit. An Open Source Python library for generating PDFs and graphics.
Let's jump to the code!
First we need to import dependencies
from PyPDF2 import PdfFileWriter, PdfFileReader import io from reportlab.pdfgen import canvas from reportlab.lib.pagesizes import letter
First we will create a new PDF with Reportlab, in this part we will also define our
font color and the
packet = io.BytesIO() can = canvas.Canvas(packet, pagesize=letter) can.setFillColorRGB(1, 0, 0) can.setFont("Times-Roman", 14) can.drawString(72, 655, "Hello from Python") can.save()
Then we move to the beginning of the StringIO buffer:
packet.seek(0) new_pdf = PdfFileReader(packet)
read your existing PDF
existing_pdf = PdfFileReader(open("original.pdf", "rb")) output = PdfFileWriter()
The we add the "watermark" (which is the new pdf) on the existing page;
page = existing_pdf.getPage(0) page.mergePage(new_pdf.getPage(0)) output.addPage(page)
And finally, write "output" to a real file:
outputStream = open("destination.pdf", "wb") output.write(outputStream) outputStream.close()
This is our result:
Thank you all.
