Summary0013001: BUG: False computation of min/max slice number in vtkImageSliceMapper
DescriptionThere is a compatibility issue in the new VTK 5.10.0. Due to the usage of new vtkImageSliceMapper inside of vtkImageActor, the vtkCornerAnnotation changed it behavior for "<slice_and_max>" text tag, when working with volume data. It shows always 1/1 instead of e.g 5/10 for volume data during interaction.
The problem is in the wring computation of min/max slice numbers in vtkImageSliceMapper.

BUG 13001: Fix backwards compatibility of GetSliceNumberMin/Max().

In VTK 5.10 the vtkImageActor was reimplemented with vtkImageSliceMapper.
As an unwanted side-effect, the use of SetDisplayExtent caused the
GetSliceNumberMin/Max methods to always return the current slice.
This patch fixes the problem and restores backwards compatibility.
