Occurs when a graphical image is in the process of changing.
property OnProgress: TProgressEvent;
__property TProgressEvent OnProgress;
For certain descendants of TGraphic, OnProgress occurs during slow processes such as loading, storing, or transforming image data. OnProgress allows applications to provide feedback to the user about the progress of the slow process.
Component writers can generate OnProgress events for new descendants of TGraphic by calling the protected Progress method. These events are propagated to the TPicture and TImage objects.
