// .NAME vtkImageMask - Combines a mask and an image.
// .SECTION Description
// vtkImageMask combines a mask with an image.  Non zero mask
// implies the output pixel will be the same as the image.
// If a mask pixel is zero,  then the output pixel
// is set to "MaskedValue".  The filter also has the option to pass
// the mask through a boolean not operation before processing the image.
// This reverses the passed and replaced pixels.
// The two inputs should have the same "WholeExtent".
// The mask input should be unsigned char, and the image scalar type
// is the same as the output scalar type.
