/**
* The PageFormatFactory is used to create PageFormats on a higher level. The Factory contains templates for all
* PageSizes defined by Adobe:
* <p/>
*
* <p/>
* Usage for creating an printjob on A4 paper with 2.5 cm border:
* <pre>
* Paper paper = PageFormatFactory.createPaper (PageSize.A4);
* PageFormatFactory.setBordersMm (paper, 25, 25, 25, 25);
* PageFormat format = PageFormatFactory.createPageFormat (paper, PageFormat.PORTRAIT);
* </code>
* <p/>
* Defining a pageformat can be an ugly task and full of dependencies. The call to
* PageFormatFactory.setBorders(...) will setup the paper"s border and always assumes
* that the paper is laid out in Portrait.
* <p/>
* Changing the PageFormat"s orientation does not change the PageFormat"s paper object,
* but it changes the way, how the paper object is interpreted.
