CAM::PDF %PDF-

fionbarr has asked for the wisdom of the Perl Monks concerning the following question:

I am having (generally) good results with CAM::PDF but a LOT of the files I am trying to read have the error

"Content does not begin with \"%PDF-\"\n";
[download]

what's the chance of ignoring this error and trying to continue?

If the file does not start with `%PDF-`, it's not a PDF file. So I would assume that your chances are pretty slim to none. Have you considered actually looking at the file contents?	[reply] [d/l]

ah ha! Adobe reader (trying to open this file) says that the file 'has been damaged (for example, it was sent as an email attachment and wasn't correctly decoded. I'll try to open it and look at it otherwise. Thanks	[reply]

I ran into problems with CAM::PDF and others, as apparently Adobe specified that line endings must be only '\n', and not the often seen '\r\n'. Thus if a file passed through something that 'translated' line endings, the strict matching would fail. Differences between specifications, specification documents, and the real world. (sigh)	[reply]
