Summary0000674: Extracted ROI is shifted wrt the whole volume
Description

In ExtractSubvolumeROI and in ChangeTracker, the resampled ROI does not coincide with the original volume exactly. The actual discrepancy depends on the resampling constant value (no discrepancy if it is 1).

The cause of the problem is that the code does not account for pixel origin being at the center, not the corner, of voxel.

TagsNo tags attached.

Initial working implementation using vtkImageReslice committed in r10746.

FIXME: incorrect initialization of colormap for resampled label volumes; handling mouse events does not account for parent transform.

TODO: correct visualization of the ROI overlay in slice views for the cases when parent transforms are present.

ExtractSubvolumeROI fixed as of r10979. ChangeTracker ROI extraction inconsistency fixed in some earlier release, did not take a note which exactly.
