beginRender Method


Stops the viewer from rendering the content if any change is applied. This is useful to increase the control's speed efficiency.


JavaScript Syntax
ImageViewer.prototype.beginRender = function() 
TypeScript Syntax
beginRender(): void; 


BeginRender and EndRender work with a similar way to BeginUpdate and EndUpdate except they will only stop the rendering of the content. Updating the transformation will continue in the usual manner.

When the final EndRender is called, the viewer will call Invalidate to render the new content.

To determine if the control will currently update the transform and invalidate, use CanRender.
