ZoomY specifies the vertical zoom. Using this property (and/or ZoomX) you lose the image aspect ratio and some functions, which require aspect ratio, may not work properly.
Setting ZoomX and ZoomY to the same value is equivalent to setting Zoom.
Note: ◼ZoomY will only have a temporary effect if AutoShrink or AutoStretch is enabled, unless you add iedoDisableAutoFitWhenZoom to DisplayOptions ◼Use ZoomFilter to improve the quality when zooming
// Stretch image to control size without maintaining the aspect ratio ImageEnView.GetIdealZoom( ZoomX, ZoomY ); ImageEnView.ZoomX := ZoomX; ImageEnView.ZoomY := ZoomY;
