onDrawImage Method

Summary

Raises the DrawImage event.

Syntax

JavaScript Syntax
ImageViewerSpyGlassInteractiveMode.prototype.onDrawImage = function(e)
TypeScript Syntax
onDrawImage(e: ImageViewerSpyGlassDrawImageEventArgs): void; // protected

Parameters

e

Event data

Remarks

Raising an event invokes the event handler through a function. The OnDrawImage method also 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.
