May 13, 2017 beginner example , PyPDF2 , python pdf library

First Install PyPDF2 with pip from cmd,
pip install PyPDF2

	# This is a PyPDF2 example found in sample_code directory.
	# I removed some parts which may cause problems for beginners.
	# Also fixed code to work with python 3+.

	from PyPDF2 import PdfFileWriter, PdfFileReader

	output = PdfFileWriter()
	input1 = PdfFileReader(open("sample.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 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)


	# finally, write "output" to document-output.pdf
	outputStream = open("PyPDF2-output.pdf", "wb")
	output.write(outputStream)
