I'm trying to find any PDF creator/exporter tool, capable of creating multi-layered PDF file. Multi-layering doesn't sound like a really hard to code feature, and thus I don't want to spend a lot of money for such application.
I'm looking for anything that could work as standalone, some open-source office app plugin (I'm aware of some Microsoft Word plugin), GIMP/Inkscape plugin, anything.
For now, the best thing that I've already found is a command line tool.
Additional pros of such software would be also ability of creating some buttons, allowing you to script around your layers.
Any suggestions or unusual ideas really appreciated.
