   userData  
)

   apply(source: lt.Controls.ImageViewerItem, change: lt.LeadPointD, userData: any): void;

Parameters

source

A lt.Controls.ImageViewerItem value that references the item to which the action applies.

change

A lt.LeadPointD value that references a custom change in data.

userData

An any value that references optional custom user data.

The userData parameter is an optional custom parameter, that may be defined at the discretion of individual developers and development environments.
