• Extract images from PDF without resampling, in python?

  - by matt wilkie

  How might one extract all images from a pdf document, at native resolution and format? (Meaning extract tiff as tiff, jpeg as jpeg, etc. and without resampling). Layout is unimportant, I don't care were the source image is located on the page. I'm using python 2.6 but can use 3.x if required. thanks

• Get CGI Fields from URL Python

  - by user299196

  When using the cgi module in Python, I can't seem to figure out how to extract CGI variables in the URL. For example if the url servercgi.py?name=user , how do I get 'name' after import cgi? For some reason, form.getvalue and form['user'] do not work but if I print the object, I see something like FieldStorage(None, None, [MiniFieldStoreage('name', 'user')]).

• Force import module from Python standard library instead of PYTHONPATH default

  - by jrdioko

  I have a custom module in one of the directories in my PYTHONPATH with the same name as one of the standard library modules, so that when I import module_name, that module gets loaded. If I want to use the original standard library module, is there any way to force Python to import from the standard library rather than from the PYTHONPATH directory, short of renaming the custom module and changing every reference to point to the new name?

  I have an RRD database, and I want to parse some of the data in it. I found this: http://pypi.python.org/pypi/PyRRD/0.0.7 but it basically just calls the command line tools (no parsing). Does anyone know of a library that will actually parse the output of rrdtool dump? Thanks!

• Should Python 2.6 on OS X deal with multiple easy-install.pth files in $PYTHONPATH?

  - by ahd

  I am running ipython from sage and also am using some packages that aren't in sage (lxml, argparse) which are installed in my home directory. I have therefore ended up with a $PYTHONPATH of $HOME/sage/local/lib/python:$HOME/lib/python Python is reading and processing the first easy-install.pth it finds ($HOME/sage/local/lib/python/site-packages/easy-install.pth) but not the second, so eggs installed in $HOME/lib/python aren't added to the path. On reading the off-the-shelf site.py, I cannot for the life of me see why it's doing this. Can someone enlighten me? Or advise how to nudge Python into reading both easy-install.pth files? Consolidating both into one .pth file is a viable workaround for now, so this question is mostly for curiosity value.

• Game engine with python scripting?

  - by Kayle

  Looking to put together a 3D side-scrolling action platformer. Since this is my first time trying to put together a non-simple adventure game, I'm at a loss for which engine to consider. I would prefer one that supports scripting in python, since that's my primary language. Without tight controls, the game will suck... so speed is a priority. Cross-platform is also important to me. Any suggestions?
