Javascript Examples to create PDF Files

The PDF creator handles many of the standard reporting functions, most notably is the handling of table structures, which is accomplished by use of a ruler. A ruler is a list of values that define columns and how they should treat the text within the cells. Text within a cell can be left, right, center or period justified. Text that exceeds the cell width can be truncated, truncated with 3 dots (...), or word wrapped. You may use as many rulers as required to format the text. Text can be placed into the document without a ruler, in this case the text will be word warped and paginated, and as text is added it will be positioned to the end of the previous text allowing font characteristics to be adjusted on a character by character basis.
