If using Gtk::Notebook, please note that we originally had notebook tabs on the dialog for Potrace, and a placeholder for "Other," meaning some other scanning algorithm. So keep in mind that it would likely need to be separated like that again in the future, and the idea of tabs-within-tabs might need to be considered.
If multiply scanning with autotrace is possible, then there might be no reason to separate trace engines with tabs there. All we need is a switcher between engines (2 radiobuttons or a combobox). Functionality is in the first place, name of engine that provides it -- in the second ;)
Well, I made the options myself, as various pre-processing and post-processing filters explicitly for Potrace's black&white tracing algorithm, so that is a very big 'If'.
I experimented with an algorithm of my own that scans a color bitmap directly, with no intermediate black&white step. It works with parameters like "color distance" and "color slope". In this case none of the existing controls would have any meaning, nor is there a "multiscan."
Someone showed me another tracer lib on the Net somewhere that does color tracing also, and I am sure it would have different parameters.
