Free editor for PDF documents. Complete editing of PDF documents is possible with PDFedit. You can change raw pdf objects (for advanced users) or use many gui functions. Functionality can be easily extended using a scripting language (ECMAScript).
This appears to be good software though it is not very intuitive. To save edited text characters in PDFedit I had to first press F5 (refresh); e.g. select text - Selection pane - selection - TJ - Parameter 0 Array - modify required characters - F5 - save
Like this software. Is there any efforts to port to qt4 or gtk. Missing out as debian has removed from repository due to dependency on qt3.
