Closed, ResolvedPublic

Description

From Image Rendering Checklist by Lucas Kulle.

Open "image1.nrrd" and "image2.nrrd" individually and check whether the cross-hair is exactly in the middle of a pixel. (image1.nrrd here is brain.nrrd).

Expected Result
The crosshair is exactly in the middle of a pixel.

Observed Result
Image in the axial view is zoomed into, while in other views it's normal.

The images mentioned in the checklist are:

  • Pic3D.nrrd
  • brain.nrrd
  • mini3D.nrrd

Looks like the Axial window was reinited to mini3D.

I think there may have been a misunderstanding in this task. With the current description, I am not able to reproduce the problem (zoomed in image when loading).
From the mentioned checklist, I understand it that the tester zoomed in himself, as the checklist recommends, to see if the crosshair is aligned with the pixels. The comment only says "Problem with the brain image. The other are working. Attachment 1", so I assume the image is only to illustrate this.
So the only problem is that brain.nrrd is not pixel-aligned automatically when loaded, only after doing a reinit. I think this step in the checklist is worded a bit unclear anyway, so it's probably best to just improve that instruction and I think that's it.

Okay, cool. Do you proceed and adapt the checklist to close this task?
