I have gotten the .net port of PDFBox from here
http://www.squarepdf.net/pdfbox-net-1-8-7
I'm not sure if it is proper to ask for support through this forum or not, but
I thought I would ask in case someone has experience with this.
I am attempting to remove the security from a PDF. Once I am through with the
process I still have a valid PDF file, and the security is removed as expected.
However, all thirty-six pages of the file are completely blank. I can do the
same process with the same pdf using Java, and everything is okay with the file
afterward (security removed and data present).
I am using Miscrosoft Visual Studio 2013
.NET Framework 4.5.2
Any suggestions or insights would be appreciated. Here is the relevant code:
//Now lets create the objects that will do the magic
PDDocument doc = PDDocument.load(fileNameTemp);
You should call openProtection() here.
I'm surprised that this works in java, although I didn't test it.
Could you upload the original, the result good and bad files?
We don't do support for the .net versions (yours is an old one anyway),
but maybe the PDFs will give some clue.
Tilman
AccessPermission ap = new AccessPermission();
//Lets set the permission to what we want
ap.setCanExtractContent(true);
ap.setCanExtractForAccessibility(true);
//Lets set the protection and apply it to our PDF
StandardProtectionPolicy spp = new
StandardProtectionPolicy("secretpassword", "", ap);
doc.protect(spp);
doc.save(fileNameTemp);
doc.close();
Thank you
