/**

* @class vtkImageWriter
|
|
* @brief Writes images to files.
|
|
*
|
|
* vtkImageWriter 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.
