I have used OpenOffice PDF Import Extension, PDFEdit and numerous other tools listed in my first posts but nothing works as well as the latest Inkscape. It has one downside though, right now. That is, you can only edit one page at a time.
So here’s a random PDF I found by googling for random PDF ;). Here’s a shot of the first page in my PDF Viewer (evince).
Now we open Inkscape click File -> Open and you will see the following dialogue box where we can choose which page to import.
Now you can see that the page imported perfectly into Inkscape and objects are editable.
and finally, here’s our slightly edited, more up-to-date version.
A few other tips.
Inkscape won’t import encrypted PDF’s. To get around this you can use pdftops
If you need to merge multiple PDF’s into a single PDF, there is a nice tool called PDFtk that can do that for you which is available for Windows, MacOSX and Linux.
