This method allows you to quickly insert an item from an HTML5 Canvas Element. It is the equivalent of the following code:
var item = new lt.Controls.ImageViewerItem();
item.canvas = canvas;
item.resolution = resolution; // Optional
InsertFromElement can be used as a shortcut for InsertFromCanvas or InsertFromImage. Passing a valid HTML5 Canvas Element to InsertFromElement will create an ImageViewerItem with the Canvas property set, just as it does with InsertFromCanvas. Similarly, passing a valid HTML Image Element to InsertFromElement will create an ImageViewerItem with the Image property set, just as it does with InsertFromImage. The item can have a value in only one of Image, Element or Canvas. Setting one value will automatically delete the values of the others.
If canvas is null, then an empty item is added.
