Summary0011111: Discrepancy of insideness between continuous and discrete index transform
DescriptionTransformPhysicalPointToIndex and TransformPhysicalPointToContinuousIndex methods of itk::Image class sometimes return different values (one method thinks the point is inside, the other one thinks it is not).

Attached are the simplified source code (with one offending point), header of the image in question, and output generated on my machine (Win7 x64, VS2008 x64 target).

Is anyone investigating this bug? If not, I will need to use workaround (test both inside functions before processing).

I submitted a description of a reproducible bug with minimum working example and a simple test case. Is it really that hard to look into this?

I tried looking into this bug, but the transformation code is quite convoluted.
