 : Function
) : any;

Parameters

angle

Rotation angle in degrees.

borderColor

The type of the border color. Possible values: 0-AutoDetect, 1-Black, 2-White. If undefined, AutoDetect value is used.

successFunc

A function that will be executed if request is executed successfully. Function prototype: "successFunc(image)", where 'image' parameter is an instance of WebAcquiredImageJS class.

errorFunc

A function that will be executed if request is failed. Function prototype: "errorFunc(image, errorMessage)", where 'image' parameter is an instance of WebAcquiredImageJS class, 'errorMessage' parameter is string that describes error.

This function sends an asynchronous request to rotate an image. If you want to use synchronous request instead of asynchronous request, please use WebAcquiredImageJS.rotate function.
