<P>
Formats text in a columnwise form. The text is bound on the left and on the right by a sequence of lines. This allows the column to have any shape, not only rectangular. <P> Several parameters can be set like the first paragraph line indent and extra space between paragraphs. <P> A call to the method <CODE>go</CODE> will return one of the following situations: the column ended or the text ended. <P> I the column ended, a new column definition can be loaded with the method <CODE>setColumns</CODE> and the method <CODE>go</CODE> can be called again. <P> If the text ended, more text can be loaded with <CODE>addText</CODE> and the method <CODE>go</CODE> can be called again.<BR> The only limitation is that one or more complete paragraphs must be loaded each time. <P> Full bidirectional reordering is supported. If the run direction is <CODE>PdfWriter.RUN_DIRECTION_RTL</CODE> the meaning of the horizontal alignments and margins is mirrored.
