Who says pdf support on linux is weak? 😉 Using free tools only, I can actually do more on linux than on windows.
A friend asked me to adapt a brochure which is in pdf format so that his contact data are filled in at the designated area on the last page. I didn’t have high hopes, as I know pdf editing is clumsy, even on windows using Adobe Acrobat. But I thought I’d give it a google search, and guess what, I stumbled upon pdfedit which seems to be able to do the job quite adequately! The only downside is the speed. I hope they port it to Qt 4 and fix the speed issues while they’re at it. 😉 (and apparently there are some plans!)
