# IProgressHandler Interface

Let a class implement this interface to be able to pass the class instance as a parameter to a image filter to let the class get progress callbacks.
Note:
A Interface is nothing but a promise, a promise that a class implements a certain interface. So any class that implements IProgressHandler is only promising to implement the methods that the IProgressHandler interface describes.
