If you are happy to for the image to be distorted (aspect ratio is ignored) then you can use:
// Stretch image to control size without maintaining the aspect ratio
ImageEnView.GetIdealZoom( ZoomX, ZoomY );
ImageEnView.ZoomX := ZoomX;
ImageEnView.ZoomY := ZoomY;
If you want to maintain the aspect ratio and are happy for edges of the image to be cut off (visually), you can use TImageEnView.FitCropping. See the examples at:
