| Leadtools.Controls Namespace > ImageViewer Object : BeginAutoSizeChanged Method |
function Leadtools.Controls.ImageViewer.beginAutoSizeChanged()
The viewer hooks to standard HTML Window "sizechanged" or "orientationchange" events depending on the browser being used. This will allow the viewer to recalculate the transformation matrix and cause a render if the size of the control (container div) changes. If an action causes mutliple size changes (for example, a CSS transition or animation) then it is recommended to call BeginAutoSizeChanged to disable the automatic update and optimize performance and then re-enable the feature by calling EndAutoSizeChanged.
Calls to BeginAutoSizeChanged and EndAutoSizeChanged are accumulative. Each call to BeginAutoSizeChanged must be matched with a corresponding call to EndAutoSizeChanged.
