|
* @brief Image Data type Casting Filter
|
|
*
|
|
* vtkImageCast filter casts the input type to match the output type in
|
|
* the image processing pipeline. The filter does nothing if the input
|
|
* already has the correct type. To specify the "CastTo" type,
|
|
* use "SetOutputScalarType" method.
|
|
*
|
|
* @warning
|
|
* As vtkImageCast only casts values without rescaling them, its use is not
|
|
* recommented. vtkImageShiftScale is the recommented way to change the type
|
|
* of an image data.
