TImageEnView.Zoom


Declaration

property Zoom: double;


Description

Use the Zoom property to zoom in or out of the image. The image itself is not modified, only its display size changes.
Zoom is expressed as a percentage of its native size, i.e. 100 is normal size, values less than 100 decrease the display size and values greater than 100 increase the display size.

Note:
 Zoom 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
 By default, scrolling the mouse wheel will zoom the view. You can limit the bounds of the zoom using OnZoomIn and OnZoomOut
