changepagestring.pl does not replace string

I tried to replace a string in a pdf file: "changepagestring.pl boven.pdf Boven Dak" However, when I tried it, I got the following error message: **** Expected object open tag 0 %PDF-1.3 %????????? 2 0 ob **** "getpdftext.pl boven.pdf" produces: **** Bovenlicht Onderkant **** Am I doing something wrong? The OS is Mac OS X, 10.4.9, Intel version. perl -v This is perl, v5.8.6 built for darwin-thread-multi-2level (with 3 registered patches, see perl -V for more detail)

I've reproduced this problem by opening the RTF in TextEdit and printing to PDF under 10.4.9. The problem is that resulting PDF is corrupt -- it wrongly claims that data starts at byte zero, when in fact the data starts at byte 22. I see that the PDF opens in both Acrobat and Preview. Those two applications must be more tolerant of corrupt PDFs than my library is... I think the correct approach is to file a bug report with Apple. Chris

Thanks for the reply. I'll report the bug to Apple. Is there any way that I can fix the PDF's manually (while waiting for the Apple fix), say by automatically replacing the starting position somewhere in the PDF?

I was about to say no, but perhaps yes. I haven't tried this: Try opening the PDF in a binary-friendly text editor (like emacs) and go to the end of the doc. Find the line that says "000000000 n" and change the "n" to an "f". If I've said that correctly, that should change the corrupt element pointing at byte zero to "unused". But then, it's been several years since I looked at the PDF spec for the document index so I could be remembering incorrectly.

Chris, just for you info: I reported the bug to Apple (5127826). I also tried what you said, and set the line: 0 18 0000000000 00000 n 0000000281 00000 n 0000000022 00000 n to: 0 18 0000000000 00000 f 0000000281 00000 n 0000000022 00000 n That nearly worked. I could run: changepagestring.pl bovenRTF.pdf 'Onder' 'Door' dak.pdf, but unfortunately, It did replace 'Onder' with 'oor', instead of 'Door'. Thanks for the effort.

I still say Apple is at fault, so I'm going to close this bug.
