Sorry, the subject line was for a related question that I decided not to ask, I forgot to change it when I changed my email. I've changed it now!
I'm using Python 3.3 on Windows with the pydicom module (http://code.google.com/p/pydicom/). Using pydicom, I've ended up with a "bytes" object of length (512*512/8 = 32768) containing a 512x512 1-bit bitmap (i.e. each byte represents 8 pixels of either 1 or 0). When I print this to screen I get: 'b\x00\x00\x00.....' I can unpack this to a tuple of the integer representations of binary data, but that doesn't really help as presume I need the binary (8 digit) representation to be able to translate that into an image. I wasn't sure which GUI library to use, so haven't specified one. As it's Python 3, Tkinter is available. I also have matplotlib and numpy installed, and PIL. Ideally, I'd like to be able to access the pixel data in the form of a numpy array so that I can perform image-processing tasks on the data. So now that I've explained myself slightly more fully, does anyone have any thoughts on how to do this?

But more importantly, what version of Python, what OS, and which GUI library (wxpython, qt, etc.) are you used to? Specify those, and somebody familiar with that particular library will probably pop up with an answer. -- DaveA -- http://mail.python.org/mailman/listinfo/python-list DISCLAIMER: This email and any attachments hereto contains proprietary information, some or all of which may be confidential or legally privileged.
