PDF
===
A Pure-Python library built as a PDF toolkit. It is capable of:
- extracting document information (title, author, ...),
- splitting documents page by page,
- merging documents page by page,
- cropping pages,
- merging multiple pages into a single page,
- encrypting and decrypting PDF files.
By being Pure-Python, it should run on any Python platform without any
dependencies on external libraries. It can also work entirely on StringIO
objects rather than file streams, allowing for PDF manipulation in memory.
It is therefore a useful tool for websites that manage or manipulate PDFs.
Examples
========
Example 1::
from PyPDF2 import PdfFileWriter, PdfFileReader
output = PdfFileWriter()
input1 = PdfFileReader(open("document1.pdf", "rb"))
# print how many pages input1 has:
print "document1.pdf has %d pages." % input1.getNumPages()
# add page 1 from input1 to output document, unchanged
output.addPage(input1.getPage(0))
# add page 2 from input1, but rotated clockwise 90 degrees
output.addPage(input1.getPage(1).rotateClockwise(90))
# add page 3 from input1, rotated the other way:
output.addPage(input1.getPage(2).rotateCounterClockwise(90))
# alt: output.addPage(input1.getPage(2).rotateClockwise(270))
# add page 4 from input1, but first add a watermark from another PDF:
page4 = input1.getPage(3)
watermark = PdfFileReader(open("watermark.pdf", "rb"))
page4.mergePage(watermark.getPage(0))
output.addPage(page4)
# add page 5 from input1, but crop it to half size:
page5 = input1.getPage(4)
page5.mediaBox.upperRight = (
page5.mediaBox.getUpperRight_x() / 2,
page5.mediaBox.getUpperRight_y() / 2
)
output.addPage(page5)
# encrypt your new PDF and add a password
password = "secret"
output.encrypt(password)
# finally, write "output" to document-output.pdf
outputStream = file("document-output.pdf", "wb")
output.write(outputStream)
Example 2::
from PyPDF2 import PdfFileReader, PdfFileMerger
merger = PdfFileMerger()
input1 = open("document1.pdf", "rb")
input2 = open("document2.pdf", "rb")
input3 = open("document3.pdf", "rb")
# add the first 3 pages of input1 document to output
merger.append(fileobj = input1, pages = (0,3))
# insert the first page of input2 into the output beginning after the second page
merger.merge(position = 2, fileobj = input2, pages = (0,1))
# append entire input3 document to the end of the output document
merger.append(input3)
# Write to an output PDF document
output = open("document-output.pdf", "wb")
merger.write(output)
