In TImageEnView, is there an event handler to detect explicitly a change of the dimensions of the TImageEnView.IEBitmap? I.e., whenever TImageEnView.IEBitmap_Width or TImageEnView.IEBitmap_Height changes, then this event is triggered.

Hi Peter

No, but if it is caused by a TImageEnProc operation then OnImageChange will occur.

Hi Nigel

Thank you for the information. However, a change in the image dimensions could have different causes, not only a TImageEnProc operation. It would be most helpful to be able to react to image dimension changes. Could you implement this vital information event?

Hi Peter

You can assign the TImageEnView.IEBitmap.OnChanged event if you need to capture that:
