Classe: Image_Transform - X-Ref

The main "Image_Resize" class is a container and base class which
provides the static methods for creating Image objects as well as
some utility functions (maths) common to all parts of Image Resize.

The object model of DB is as follows (indentation means inheritance):

Image_Resize The base for each Image implementation.  Provides default
|            implementations (in OO lingo virtual methods) for
|            the actual Image implementations as well as a bunch of
|            maths methods.
