  54 A generic binary operation on views<p>
  55 Use this class as a convenience superclass when defining an operation for any <a class="el" href="g_i_l_0038.html" title="container interface over image view. Models ImageConcept, PixelBasedConcept">image</a> views. Many operations have different behavior when the two views are compatible. This class checks for compatibility and invokes apply_compatible(V1,V2) or apply_incompatible(V1,V2) of the subclass. You must provide apply_compatible(V1,V2) method in your subclass, but apply_incompatible(V1,V2) is not required and the default throws std::bad_cast. <table border="0" cellpadding="0" cellspacing="0">
