[vtkusers] point picking question

[Anja Ende]

Hi everyone,

I have a reslicer interface where I click on a 2D image and it reslices the
volume at that point and returns me the slice.

Now, I could have the image zoomed and I want to pick the point in the
original image regardless of the zoom factor. Of course, I can probably do
that by taking the current zoom factor into account but there might be round
off errors, so I was wondering if there is a better way.

I can get the points bu using vtkPointPicker class and that seems to work.
However, I do not know what to do with those values as the reslicer will not
accept those values.

So, I was wondering if there was a way to pick points on the rendered 2D
image (regardless of its zoom factor) that actually refers to the points in
the original image size.

Cheers and thanks,

Anja

I actually have another open question. I still have not figured out the
correct strategy for setting the output setting. So, if someone would be
kind enough to help me with that
