Detailed Description

template<class TImage, class TAccessor>
class itk::ImageAdaptor< TImage, TAccessor >

Give access to partial aspects of voxels from an Image.

ImageAdaptors are templated over the ImageType and over a functor that will specify what part of the pixel can be accessed

The basic aspects of this class are the types it defines.

Image adaptors can be used as intermediate classes that allow the sending of an image to a filter, specifying what part of the image pixels the filter will act on.

The TAccessor class should implement the Get and Set methods as static methods. These two will specify how data can be put and get from parts of each pixel. It should define the types ExternalType and InternalType too.
