OleFileIO_PL
|
||||
============
|
||||
|
||||
[OleFileIO_PL](http://www.decalage.info/python/olefileio) is a Python module to read [Microsoft OLE2 files (also called Structured Storage, Compound File Binary Format or Compound Document File Format)](http://en.wikipedia.org/wiki/Compound_File_Binary_Format), such as Microsoft Office documents, Image Composer and FlashPix files, Outlook messages, ...
|
||||
|
||||
This is an improved version of the OleFileIO module from [PIL](http://www.pythonware.com/products/pil/index.htm), the excellent Python Imaging Library, created and maintained by Fredrik Lundh. The API is still compatible with PIL, but I have improved the internal implementation significantly, with bugfixes and a more robust design.
|
||||
|
||||
As far as I know, this module is now the most complete and robust Python implementation to read MS OLE2 files, portable on several operating systems. (please tell me if you know other similar Python modules)
|
||||
|
||||
WARNING: THIS IS (STILL) WORK IN PROGRESS.
|
||||
|
||||
Main improvements over PIL version:
|
||||
-----------------------------------
|
||||
|
||||
- Better compatibility with Python 2.4 up to 2.7
|
||||
- Support for files larger than 6.8MB
|
||||
- Robust: many checks to detect malformed files
|
||||
- Improved API
|
||||
- Added setup.py and install.bat to ease installation
|
||||

How to use this module:
|
||||
-----------------------
|
||||
|
||||
See sample code at the end of the module, and also docstrings.
|
||||
|
||||
Here are a few examples:
|
||||
|
||||
:::python
|
||||
import OleFileIO_PL
|
||||
|
||||
# Test if a file is an OLE container:
|
||||
assert OleFileIO_PL.isOleFile('myfile.doc')
|
||||
|
||||
# Open an OLE file:
|
||||
ole = OleFileIO_PL.OleFileIO('myfile.doc')
|
||||
|
||||
# Get list of streams:
|
||||
print ole.listdir()
|
||||
|
||||
# Test if known streams/storages exist:
|
||||
if ole.exists('worddocument'):
|
||||
print "This is a Word document."
|
||||
print "size :", ole.get_size('worddocument')
|
||||
if ole.exists('macros/vba'):
|
||||
print "This document seems to contain VBA macros."
|
||||
|
||||
# Extract the "Pictures" stream from a PPT file:
|
||||
if ole.exists('Pictures'):
|
||||
pics = ole.openstream('Pictures')
|
||||
data = pics.read()
|
||||
f = open('Pictures.bin', 'w')
|
||||
f.write(data)
|
||||
f.close()
|
||||
|
||||
|
||||
It can also be used as a script from the command-line to display the structure of an OLE file, for example:
|
||||
|
||||
OleFileIO_PL.py myfile.doc
|
||||
|
||||

||||
|
||||
How to contribute:
|
||||
------------------
|
||||
|
||||
The code is available in [a Mercurial repository on bitbucket](https://bitbucket.org/decalage/olefileio_pl). You may use it to submit enhancements or to report any issue.
|
||||
|
||||
If you would like to help us improve this module, or simply provide feedback, you may also send an e-mail to decalage(at)laposte.net. You can help in many ways:
|
||||
|
||||
- test this module on different platforms / Python versions
|
||||
- find and report bugs
|
||||
- improve documentation, code samples, docstrings
|
||||
- write unittest test cases
|
||||
- provide tricky malformed files
|
||||
|
||||
How to report bugs:
|
||||
-------------------
|
||||
|
||||
To report a bug, for example a normal file which is not parsed correctly, please use the [issue reporting page](https://bitbucket.org/decalage/olefileio_pl/issues?status=new&status=open), or send an e-mail with an attachment containing the debugging output of OleFileIO_PL.
|
||||
|
||||
For this, launch the following command :
