Hello.I've experiencing some problem using protected PDFs.I've been asked to
make a small java program that shows a list of PDFs, allows the user to see
them in a viewer and to print them with the application of a watermark on the
printed copy.
First of all I looked if it was possible to launch the PDFs in acrobat reader
disabling the printing command, but after some search over the internet it
didn't looked possible, so I developed a small viewer using the PDFrenderer
library.The printing part, I used iText to process the PDF applying a watermark
page by page, save it in a temporary file and then print the temporary file.
With PDFs I printed the program works fine, both the viewer and the printer
work properly, but using PDFs protected, in both the modules I get the same
error:
com.sun.pdfview.PDFParseException: Unknown command: qq
at com.sun.pdfview.PDFParser.iterate(PDFParser.java:800)
at com.sun.pdfview.BaseWatchable.run(BaseWatchable.java:101)
at java.lang.Thread.run(Thread.java:662)
when I call the method getPage(int pageNum) of the class PDFFile.I found on the
internet that the problem seem quite common, but couldn't understand how to get
rid of it. Someone can help?
Thanx in advance
