I am generating some PDFs from scratch. One of the files opens fine in Acroba but it still clearly has a structural problem because if I check the file with the preflight in Acrobat it says thet the file is damaged and needs repair, and if I close the file without eding anything Acrobat asks if I want to save the file. Acrobat does not say what the problem is, and I am unable to find the problem by inspecting it. It is quite a basic file and is easily inspectible using a text editor.
I have tried validating the pdf using different validators, but I have found no validators which will report on "structural" problems in the file, so I have tried to inspect the file using a text editor and also a binary-editor to check that offsets of the objects are at the correct place and that the stream lengths are right.
I am unable to find any problems by inspecting it manually so I don't understand what I am missing. And I don't know of any tools which can do this.
(I have got Acrobat Pro 8, but I am not an expert in using it so I don't know if it can be used to "debug" the file)
Anyway, if anyonecan give me any hints on how to solve this, it would be much appreciated.
And, if anyone wants to take a look at my testfile, it can be downloaded from here: https://www.box.com/files/0/f/0/1/f_3946274006
Again, the file is easily readable in a text editor since none of the streams are compressed...
Thanks in advance for any help!!
