Image_Transform

Description

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. | +-Image_GD The Image implementation for the PHP GD extension . Inherits Image_Resize When calling DB::setup for GD images the object returned is an instance of this class.
