Detailed Description

template<typename TInternalType, typename TExternalType>
class itk::PixelAccessor< TInternalType, TExternalType >

Give access to partial aspects of a type.

PixelAccessor is templated over an internal type and an external type representation. This class encapsulates a customized conversion between the internal and external type representations.

PixelAccessor is designed to be used in conjunction with ImageAdaptors. An ImageAdaptor take an image and present it as another image in which the pixels are a pixel-to-pixel modification of the original image.

ImageAdaptors are intended to perform task similar to ImageFilters, but reducing the overhead in memory allocation, at the price of some reduction in performance.

ImageAdaptors are templated over a PixelAccessor class that will define what kind of transformation is applied to the pixel data. Typical uses of PixelAccessor include basic type casting, (e.g. make a float image looks like a unsigned int image).

Every Image has a default PixelAccessor that performs an identity operation. ImageIterators use the PixelAccessor defined by the image in order to get and set the values of pixels.
