After learning the basics of PDFs you might be wondering where to start. I would suggest going through some PDFs to be comfortable with their structure. You can look at a PDF file's structure using the PDFDebugger. For more details visit http://www.printmyfolders.com/view-structure-of-a-pdf If you are interested in view the exact location of objects in the raw file you could use a little app that I created. Here is the link.This is a jar file that can be open a PDF file with its raw contents. Open a PDF file using File -> Open The file that I have opened is displayed. Looking at the end of the PDF I can see that the XREF table is 4791 bytes from the beginning of the PDF. Key in this value in the text field and click "Go to location". |
