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.

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.

interface IProgressHandler


OnProgressAlgorithms that use the IProgressHandler interface will call this method when they want to give a notice of a progress.
