Manipulating existing PDFs

In this chapter, we're going to solve some problems when working with existing PDFs that need to be split into different files, merged or stamped. Usually, we are going to use a combination of PdfReader to read the document and PdfStamper, PdfCopy or PdfSmartCopy to create a new PDF. Note that we'll skip filling out interactive forms for now. We'll deal with AcroForm and XFA technology in the next chapter.
