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
