/**
 * @class   vtkPImageWriter
 * @brief   Writes images to files.
 *
 * vtkPImageWriter writes images to files with any data type. The data type of
 * the file is the same scalar type as the input.  The dimensionality
 * determines whether the data will be written in one or multiple files.
 * This class is used as the superclass of most image writing classes
 * such as vtkBMPWriter etc. It supports streaming.
