[Insight-users] Reslice volume according to 'Image Orientation' Dicom tag.

[Laurent PAUL]

Hi Andinet,

I would like to rotate volume aligning rows on X axe and column on Y axe.
In fact rotate the volume as if the dicom tag 'Image Orientation' was
1\0\0\0\1\0.

I found OrientImageFilter (just below OrientedImage, thanks!), I think it
can do the job.

Thanks,

Laurent.

I'd want to align rows and columns respectively on X and Y axes. I know
there a class in VTK to reslice volume (great to dispaly coronal,
sagittal and transversal views!).
