Detailed Description

template<class TInputImage, class TOutputImage>
class itk::CastImageFilter< TInputImage, TOutputImage >

Casts input pixels to output pixel type.

This filter is templated over the input image type and the output image type.

A typical use is to cast a

 itk::Image<type1, dim>

to a

 itk::Image<type2, dim>

This filter can also be used to cast a

 itk::VectorImage<type1, dim>

to a

 itk::VectorImage<type2, dim>

If you need to perform a dimensionaly reduction, you may want to use the ExtractImageFilter instead of the CastImageFilter.

virtual

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Reimplemented from itk::UnaryFunctorImageFilter< TInputImage, TOutputImage, Functor::Cast< TInputImage::PixelType, TOutputImage::PixelType > >.

template<class TInputImage, class TOutputImage>

void itk::CastImageFilter< TInputImage, TOutputImage >::GenerateData ( )

inlineprotectedvirtual

A version of GenerateData() specific for image processing filters. This implementation will split the processing across multiple threads. The buffer is allocated by this method. Then the BeforeThreadedGenerateData() method is called (if provided). Then, a series of threads are spawned each calling ThreadedGenerateData(). After all the threads have completed processing, the AfterThreadedGenerateData() method is called (if provided). If an image processing filter cannot be threaded, the filter should provide an implementation of GenerateData(). That implementation is responsible for allocating the output buffer. If a filter an be threaded, it should NOT provide a GenerateData() method but should provide a ThreadedGenerateData() instead.

PushBackInput(), PushFronInput() in the public section force the input to be the type expected by an ImageToImageFilter. However, these methods end of "hiding" the versions from the superclass (ProcessObject) whose arguments are DataObjects. Here, we re-expose the versions from ProcessObject to avoid warnings about hiding methods from the superclass.
