The GIMP imports PDF files nicely, and I usually print the file to PDF after I am done. Now, if you have a many page document, the GIMP will import each page as a layer which can make it a pain to have to manually print each layer as a separate pdf, but ya do what ya gotta do. I also like PDFShuffler for managing/mangling pdf files. Its in portage by the way. HTH, quantum -- Matthew W. Summers
