Hi, a first guess would be that you mix up indices with world coordinates and Z just seems to work coincidentally since it might have a spacing of 1. As an additional note be careful when working with world coordinates and indices in parallel as pixel coordinates are center-based, e.g., a pixel with extents [1, 1, 1] in world coordinates at the origin has the bounds [-0.5, 0.5, -0.5, 0.5, -0.5, 0.5] in world coordinates.

I have used the mitk::boundingobjectcutter class and am confused with the output I get from the cropping. I manually enter the bounds for the bounding object which are the 6 parameters in the form xmin, xmax, ymin, ymax, zmin, zmax. I am having trouble explaining the output image dimensions that I recieve. my input impage has a dimenion : 512X512X1320 bounds parameters : 50 100 60 150 10 1150 output dimensions : 116 209 1140 as the output object according to me shoulde have dimensions in X as xmax - xmin, Y as ymax - ymin and Z as zmax- zmin. the output dimension for the Z axis seems to be the way I expect but X and Y axes give out "weird" values of 106 and 209 respectively. Can anybody explain this behaviour ? Is there another way to do the cropping ?
