OnDrawImage Method (ImageViewerSpyGlassInteractiveMode)

Summary

You can override this method to draw your own image on the magnify glass rectangle available through SpyRectangleShape.

Syntax

Java

Objective-C

WinRT C#

protected virtual void OnDrawImage()

Protected Overridable Sub OnDrawImage()

protected virtual void OnDrawImage()

- (void)onDraw:(CGContextRef)context touchLocation:(CGPoint)point

protected void onDrawImage(ImageViewerSpyGlassDrawImageEvent event)

function Leadtools.Controls.ImageViewerSpyGlassInteractiveMode.OnDrawImage()

Remarks

The OnDrawImage method allows derived classes to handle the event without attaching a function to the event. This is the preferred technique for handling the event in a derived class.

Note to Inheritors: When overriding OnDrawImage in a derived class, be sure to call the base class's OnDrawImage method so that registered delegates receive the event.
