Hi Zach
Attached is some code for removing radial distortion from images. It
shows how to draw lines based on user input using matplotlib. It is
not suited for a big application, but useful for demonstrations.
Try it on

Hi Stéfan,
Thanks -- I hadn't realized matplotlib's user-interaction abilities
were that sophisticated! I'll definitely give that route a shot.

I am not sure I got what you mean but I am using PIL to convert arrays
to images and viceversa

I embed bmps using wxpython.

I'm not sure if you're after anything specific, but a very convenient
way to show 2-D arrays on screen is

Pyglet looks relatively easy -- you can feed an image buffer object
with a string or a ctypes pointer.

some.
Are
there ways of allowing a numpy array and a wxPython image to point to
the same memory?
yup. You can build a wxImage

Thanks for the suggestions, everyone! All very informative and most
helpful.
For what it's worth, here's my application: I'm building a tool for
image processing which needs some manual input in a few places (e.g.
user draws a few lines). The images are greyscale images with 12-14

If you want to explore the array interactively, blink images, mess with
colormaps using the mouse, rescale the image values, mark regions, add
labels, look at dynamic plots of rows and columns, etc., get the ds9
image viewer and the xpa programs that come with it that allow it to
communicate with
