TImageEnView.ZoomOut
Declaration
procedure ZoomOut(FitAndFullOnly: Boolean = False; X: Integer = -1; Y: Integer = -1);
Description
Provides a convenient method to handle clicking of a "Zoom Out" button. Each time
ZoomOut is called it decreases the zoom by a logical step, e.g. 100 to 75, 75 to 50, etc. (FitAndFullOnly = False).
It also includes "Fit to Window" as one of the steps.
If FitAndFullOnly = True, then there are only two steps, "Fit to Window" or 100% zoom.
If X and Y are specified, then it will
zoom out from the specified position (in client coordinates). Zooming will be smooth if miSmoothZoom is specified for
MouseInteractGeneral.
Note:
◼ZoomOut 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
