Get the point position in the coordinate before reslicing.

[superzz]

vtkImageReslice can present resliced images to GUI very well when AutoCropOutput is turned on. However, when user click a point(x1,y1,z1) in the resliced image, how to know its position (x0,y0,z0) in the coordinate before reslicing?

I've tried different pickers but its seems that none of them works.

Thanks
