Dear all What is your experience with corrupted PDF files? Do you know any tool that can attempt to repair damaged PDF files? Does it make any sense to edit a PDF file in hex mode?
I have a damaged PDF that cannot be opened with any of the about 10 tools that I've just tried. liv@liv-laptop:/tmp$ pdf2ps Class\ 1.pdf **** Warning: File has a corrupted %%EOF marker, or garbage after %%EOF. **** Warning: An error occurred while reading an XREF table. **** The file has been damaged. This may have been caused **** by a problem while converting or transfering the file. **** Ghostscript will attempt to recover the data.

Error: Top-level pages object is wrong type (null) Error: Couldn't read page catalog Any ideas how I could try to repair it? (It's not sensitive and it's small, so I could post it.)
