Creating pdf 1.4 with imagemagick

[dango]

Hello everybody
I'm a new imagemagick user. I need to create a pdf file (with a single image inside) starting from a png file. I'm on Ubuntu 7.04. I simply opened my shell and keyed in:

Code: Select all

convert image.png image.pdf

The result is a pdf file, but the version of pdf is 1.3. How can I obtain a pdf 1.4?

Thank you in advanced for your help.

At a guess it depends on your version of Ghostscript ?

Thank you for your answer.
Then you think that it depends on my version of Ghostscript...it's probable. How can I check which version I've got? I'm on Ubuntu Linux.

I am afraid I do not know how to check which version you have installed. All I can say is search google.

I don't believe IM uses ghostscript to output PDF, only read it. IM just uses a simple wrapper around the image to generate PDF. Not much, but enough. That is my understanding, I could be wrong.
