Displaying multiples images

[jip]

Is there a simple way to display multiple images of various size with
matplotlib ...or something else?

Is subplot() not what you want?

Do you want to display them as a montage or scroll through them individually?

I try to make a montage. I have an example here:http://
dip4fish.blogspot.com/2011/03/trying-to-make-images-mosaic-with.html
I tried without success pylab.subplot (see the script), I try also to
understand how could I do with chaco. pygame might also be a
solution...
I am also interested in scrolling through for further classification
with scikit.learn/orange

I think a library that gives you access to a canvas may be useful.
The simplest method is to construct a large array of zeros, and to
then simply update the values to the different images, and plot it as
a single image. Another option would be to use something like Cairo
or Pyglet, and ask it to display the images at the appropriate
positions.

I am trying to persist in using pylab.subplot(), but I don't know
something since subplot() didn't yield what I was waiting:

Jean-Patrick: you are using subplot incorrectly. Perhaps you are
misunderstanding the first two arguments. If you want to do a 2*2 grid
you declare that as:

subplot(2,2,1)
imshow(upperleftimage)
subplot(2,2,2)
imshow(upperrightimage)
subplot(2,2,3)
imshow(lowerrleftimage)
subplot(2,2,4)
imshow(lowerrightimage)

In your case, you had subplot(2,1,3) where 3 is larger than the number
of subplots. This needs to be less or equal to the product of the
first two numbers 2*1=2.

Hope that helps.
