Hi Uwe, I should send these messages from my member e-mail number
Thanks for that. As you can see from the last bit of my code, I tried that, but it gave the same results. I had a look at pdf.options() but didn't see anything there either to make the text stay on the same spot. It seems to also happen if you use png().
