To rotate the text the Component.createImagemethod is used. This means that this class needs to knowthe component that will receive the text. If the component is notknown the text cannot be rotated and the class will fall back to theTextLine.draw method.<P>The text is rotated by running the image through an ImageFilter. This filtercan easily be modified to rotate text through an arbitrary angle butunless the text is large the integer mapping will blur the text. Also positioning of arbitrarily rotated text becomes problematic.<dl> <dt> <b>Version:</b> <dd> 1.5, 1996/10/23 03:13:45 <dt> <b>Author:</b> <dd> Leigh Brookshaw</dl><hr><a name="index"></a><h2> <img
