Good morning everyone,
Back again with another Python question. I am using the module PyPDF2 to manipulate PDFs. You can add pages, rotate them, merge, or split PDF documents. You can also compress them, something I'd like to leverage as our program has over 17,000 PDFs on our network.
I am working with the PyPDF 2module and trying a simple rotate without success. I would like to open a given document, rotate it, and then save it as the same document. Whether I use the variable "fullPath" or a literal string with the path, I keep getting the error invalid argument and I can't figure out why. If I can do this, I think I could also figure out the compress function PyPDF2 offers as well.
--------------------------------------
Here is my code:
--------------------------------------
import os
from PyPDF2 import PdfFileWriter, PdfFileReader
path = r"H:\Documents\Compression_Test_Folder"
for root, dirs, files in os.walk(path):
for fileName in files:
fullPath = os.path.join(root, fileName)
basename, extension = os.path.splitext(fullPath)
if extension == ".pdf":
output = PdfFileWriter()
inputStream = open(fullPath, "rb")
input1 = PdfFileReader(inputStream)
output.addPage(input1.getPage(0).rotateClockwise(90))
del input1
outputStream = file(fullPath, "wb")
output.write(outputStream)
-------------------------------------------------
And here is the error message result:
--------------------------------------------------
Traceback (most recent call last):
File "I:\ARC\Data\Expressions\Clean_CountPDFPage.py", line 14, in <module>
input1 = PdfFileReader(inputStream)
File "C:\Python27\ArcGIS10.1\lib\site-packages\PyPDF2\pdf.py", line 831, in __init__
self.read(stream)
File "C:\Python27\ArcGIS10.1\lib\site-packages\PyPDF2\pdf.py", line 1279, in read
stream.seek(-1, 2)
IOError: [Errno 22] Invalid argument
Any thoughts?
