The Update method refreshes the TImageEnView component view with the current state of the image and redraws the client area.
You must call Update
or UpdateNoPaint() whenever IEBitmap
is modified by your code.
Update is called automatically when an image processing or I/O operation is executed.
// Draw a rectangle on the image and show it
ImageEnView1.IEBitmap.Canvas.Rectangle(5, 5, 100, 100);
