Here is another example which will help you understand how to do
interaction. You can drag t
Hi Stéfan,
Thanks -- I hadn't realized matplotlib's user-interaction abilities
were that sophisticated! I'll definitely give that route a shot.

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

I was misinformed about the status of numdisplay's pages. The package
is available as both part of stsci_python and independently, and its
(up-to-date) home page is here:

Googling numdisplay finds that page.

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
bits of
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

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 from

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

Hello all,
I'm curious if people have experience with / preferences for how to
display a numpy array onscreen as an image.
Pyglet looks relatively easy -- you can feed an image buffer object
with a string or a ctypes pointer. I presume getting a string from an
array is plenty fast, but the
