/** \class LabelMapMaskImageFilter
* \brief Mask and image with a LabelMap
*
* LabelMapMaskImageFilter mask the content of an input image according
* to the content of the input LabelMap. The masked pixel of the input image
* are set to the BackgroundValue.
* LabelMapMaskImageFilter can keep the input image for one label only, with
* Negated = false (the default) or it can mask the input image for a single label, when
* Negated equals true. In Both cases, the label is set with SetLabel().
