transformation [Protocol Class]
Summary: The protocol class of all transformations. There are one or more subclasses of transformation that implement transformations, the exact names of which are explicitly unspecified. If you want to create a new class that behaves like a transformation, it should be a subclass of transformation . Subclasses of transformation obey the transformation protocol.
All of the instantiable transformation classes provided by CLIM are immutable.
Summary: Returns t if object is a transformation; otherwise, it returns nil .
Summary: An instance of a transformation that is guaranteed to be an identity transformation, that is, the transformation that "does nothing."
Summary: The class that is the superclass of the following three conditions. This class is a subclass of error .
Summary: The error that is signaled when make-3-point-transformation is given three collinear image points.
Summary: The error that is signaled when make-reflection-transformation is given two coincident points.
Summary: The error that is signaled when invert-transformation is called on a singular transformation, that is, a transformation that has no inverse.
