Object.defineProperty('backImage');
Type | Description |
---|---|
Leadtools.Html.ImageElement | The background image element. |
This value is null when the viewer is first initialized or when ImageUrl is set while the value of UseBackCanvas is true or when ImageSize is set manually. In this mode, the viewer will use BackCanvas instead and BackImage is not used.
When the user sets the image using ImageUrl while the value of UseBackCanvas is false, the background image element is created and populated with the value and then is used to be applied to the foreground canvas when needed.
