All Implemented Interfaces:

Serializable

public class RotateTextEffect
extends TextEffect

Rotates the given text. Please note that this MIDP 2.0 only effect assumes that only one line is rendered - rendering several lines decreases performance drastically.

Activate this text effect by specifying text-effect: rotate; in your polish.css file. You can finetune the effect with following attributes:

• text-rotate-angle: The angle by which the text should be rotated.
