/**

|
* <p>This class is the base of the PDF generator. A PDFDocument class is
|
|
* created for a document, and each page, object, annotation,
|
|
* etc is added to the document.
|
|
* Once complete, the document can be written to an OutputStream, and the PDF
|
|
* document's internal structures are kept in sync.</p>
|
|
*
|
|
* <p>Note that most programmers using this package will NEVER access
|
|
* one of these objects directly. Most everything can be done using
|
|
* <code>PDFJob</code> and <code>PDFGraphics</code>, so you don't need
|
|
* to directly instantiate a <code>PDFDocument</code></p>
|
|
*
|
|
* <p>ezb - 20011115 - Wondering if the constructors should even be public.
|
|
* When would someone want to make one of these and manipulate it outside
|
|
* the context of a job and graphics object?</p>
