ColumnText (openpdf 1.2.7 API)

java.lang.Object
- com.lowagie.text.pdf.ColumnText

```
public class ColumnText
extends Object
```
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.
Several parameters can be set like the first paragraph line indent and extra space between paragraphs.
A call to the method go will return one of the following situations: the column ended or the text ended.
I the column ended, a new column definition can be loaded with the method setColumns and the method go can be called again.
If the text ended, more text can be loaded with addText and the method go can be called again.
The only limitation is that one or more complete paragraphs must be loaded each time.
Full bidirectional reordering is supported. If the run direction is PdfWriter.RUN_DIRECTION_RTL the meaning of the horizontal alignments and margins is mirrored.
