Search & replace PDF text or images in Python

Sample Python code to use PDFTron SDK for searching and replacing text strings and images inside existing PDF files (e.g. business cards and other PDF templates). Unlike PDF forms, the ContentReplacer works on actual PDF content and is not limited to static rectangular annotation regions. Learn more about our PDF Editing & Manipulation Library.

	# Example 1) Update a business card template with personalized info

	replacer = ContentReplacer()
	page = doc.GetPage(1)
	img = Image.Create(doc.GetSDFDoc(), input_path + "peppers.jpg")
	replacer.AddImage(page.GetMediaBox(), img.GetSDFObj())
	# next, replace the text place holders on the second page
	replacer.AddString("NAME", "John Smith")
	replacer.AddString("QUALIFICATIONS", "Philosophy Doctor")
	replacer.AddString("JOB_TITLE", "Software Developer")
	replacer.AddString("ADDRESS_LINE1", "#100 123 Software Rd")
	replacer.AddString("ADDRESS_LINE2", "Vancouver, BC")
	replacer.AddString("PHONE_OFFICE", "604-730-8989")
	replacer.AddString("PHONE_MOBILE", "604-765-4321") 
	replacer.AddString("EMAIL", "")
	replacer.AddString("WEBSITE_URL", "")
	# finally, apply

	doc.Save(output_path + "BusinessCard.pdf", SDFDoc.e_linearized)

	print("Done. Result saved in BusinessCard.pdf")

	# Example 2) Replace text in a region with new text

	doc = PDFDoc(input_path + "newsletter.pdf")

	replacer = ContentReplacer()
	page = doc.GetPage(1)

	doc.Save(output_path + "ContentReplaced.pdf", SDFDoc.e_linearized)

	print("Done. Result saved in ContentReplaced.pdf")
