Logo JPG on multi page PDF

[Hedgehoguse]

Hello,
I want to place a logo on each page of the PDF file. I'm trying:

Code: Select all

convert ( file.pdf[0] water.jpg -gravity NorthWest -compose multiply -composite ) file.pdf -delete 1 result.pdf

But the logo put on the first page only.
Thanks for help.

file.pdf[0]
This is telling IM to use page 1 only - try removing the [0]

Thank you!
I still do not quite understand the syntax IMagick.

You are not using Imagick but command line.

Imagick is built into php whereas Imagemagick can be run from the command line in php.

There are lots of examples here: http://www.imagemagick.org/Usage/

Are you using it from php ? as I have some examples on my site as well.

Yes, I do it in PHP, but it's easier to think using the command line. Pardon
