## Detailed Description

Create PDF file.

This class is responsible for the creation of a PDF file from the Ipe data. You have to create a PdfWriter first, providing a file that has been opened for (binary) writing and is empty. Then call createPages() to embed the pages. Optionally, call `createXmlStream` to embed a stream with the XML representation of the document. Finally, call `createTrailer` to complete the PDF document, and close the file.

Some reserved PDF object numbers:

- 0: Must be left empty (a PDF restriction).
- 1: XML stream.
- 2: Parent of all pages objects.
- 3: ExtGState resource from pdflatex
- 4: Shading resource from pdflatex
- 5: Pattern resource from pdflatex
- 6: ColorSpace resource from pdflatex
