+ * Remark: I looked at the interface javax.swing.text.Element, but I decided to + * write my own text-classes for two reasons: + *

    + *
  1. The javax.swing.text-classes may be very generic, I think they are + * overkill: they are to heavy for what they have to do. + *
  2. A lot of people using iText (formerly known as rugPdf), still use + * JDK1.1.x. I try to keep the Java2 requirements limited to the Collection + * classes (I think they're really great). However, if I use the + * javax.swing.text classes, it will become very difficult to downgrade rugPdf. + *
