class itk::Accessor::RGBToLuminancePixelAccessor< TInternalType, TExternalType ></h3>
Give access to Luminance of a color pixel type.
<p>
<a class="el" href="classitk_1_1Accessor_1_1RGBToLuminancePixelAccessor.html" title="Give access to Luminance of a color pixel type.">RGBToLuminancePixelAccessor</a> is templated over an internal type and an external type representation. This class cast the input applies the funtion to it and cast the result according to the types defined as template parameters. The input pixel type must support the GetLuminance() method. This is the case of the <a class="el" href="classitk_1_1RGBPixel.html" title="Represent Red, Green and Blue component for color images.">RGBPixel</a> class for example.
