TCPDF - PHP class for PDF / Discussion / Help: Problem when generating file with images

grbillo - 2011-05-31

Hi,
I’m using TCPDF to generate pdf using mainly MultiCell and Image methods. It
works perfectly excepted sometime when PDF contains large number of images. I
get then the following PDF message: File doesn’t start by ‘%PDF-‘. If I remove
one or more image, PDF is correctly generated.
I have turned around this problem for a while and haven’t been able to fix it.
Any idea ?
Thanks for your help.

Are you using the latest TCPDF version?
Can you provide a very simple script to reproduce the problem using (for
example) a for loop and a default image?

Hi,

I'm back after a while...

Yes,nicolaasuni, I use the very latest TCPDF version and it's the same...

I didn't done any progress on the problem itself but I found something that
may help:

when I save the file to disk first and then open it with Reader it works fine

when I send the file inline to browser the problem occurs and I get the PDF error message: File does not begin with '%PDF-‘.

Maybe this could help someone to get an idea.

Thanks for your help.

you are probably triggering some PHP error.
Try to open the generated PDF file with an hex editor and read it, probably
you will notice a PHP error inside.
