StreamingImageVirtualWriter propagates empty regions
Mantis Issue 703, reported by gpasero, assigned to ghost, created: 2013-04-17
The virtual writer propagates an empty input requested region at each update, which is incompatible with some filters (such as otb::UnaryFunctorWithIndexImageFilter). It can be detected as a crop problem with the largest possible region and then an exception is raised.
The virtual writer inherits from ImageToImageFilter (although it has no usefull output). Its Update method will by default propagate the input requested region (which is set to {0,0} {0,0}) before doing the real work in GenerateData.
I suggest doing a fix as seen in : http://hg.orfeo-toolbox.org/OTB/rev/311116cceee0 (re-implement Update method to prevent this dangerous empty region propagation).
