Hi
The gradient_bar example flips the bars using svg, pdf and eps backends.
Add
fig.savefig(“gradient_bar.png”)
fig.savefig(“gradient_bar.pdf”)
fig.savefig(“gradient_bar.eps”)
fig.savefig(“gradient_bar.svg”)
to gradient_bar.py to reproduce.
Tested with TkAgg backend (pylab: 1.3.0.dev5867 on python 2.5.2).

There's a bug filed for this. I've looked at it a few times, but I'm not sure how the image flipping parameters are "supposed" to work. Anyone else want to have a look at this?

I was not aware of that, thanks Michael. Just to be clear, (in relation to the filed ticket), the screen image is just fine for my part, its only after saving in any vector graphic format I get a “flipped” image as a result. In other words, I have an issue with savefig, while the ticket is concerned with imshow. Perhaps they are obviously related … then Im sorry for the noise 
Thanks,
Arnar

No problem. I didn't mean to imply that you should have known you bug was a duplicate. I was mainly pointing it out for other developers to keep track of the issue, since I suspect your issue and the one in the bug are the same, but that's probably not obvious to most users.
I suspect the fix is as simple as twiddling a single line of code, it's just not obvious to me how the image flipping is supposed to work to have consistent behavior across backends -- and I hope another developer here has a clue...
Thanks for your report,
Mike
