Hi,
I'm trying to create an application that, among other things, will allow me to view an image, zoom into it, and move it around. Essentially what I can do by using imshow and show in ipython. However, I've noticed that in both interactive usage and my application the image comes up in a small set of axes that do not fill up the screen 100% (the image is rectangular). Zooming or dragging the image around then causes part of it to go off the axes, which is not desirable.
What I would like to do is increase the size of the area where the image can be displayed to the area given to the canvas in my application. Then, if I drag the image around, part of it won't disappear. However, I'm not really sure how to do this. What is the best way to accomplish this goal (preferably for non-interactive usage - I'm using the QT4 back end)?
Thank you in advance,
David Levitan
You can set the size of the axes you want using
ax = fig.add_axes([left, bottom, width, height])
where all numbers are fractions of figure size, eg
ax = fig.add_axes([0.1, 0.1, 0.8, 0.8])
My guess is what you are experiencing may result from the image aspect
handling. Try setting the aspect to 'auto' when you create your image
ax.imshow(X, aspect=' auto')
