Class ChangeableAttributedString

java.lang.Object
  com.octo.captcha.component.image.textpaster.ChangeableAttributedString

public class ChangeableAttributedString
extends java.lang.Object

This class is the decomposition of a single AttributedString into its component glyphs. It wouldn't be necessary if Java2D correctly handled spacing issues with fonts changed AffineTransformation -- there is a possibility that it will not be necessary with java 1.5
