Camus: Talk to you privately. (the rest of this post is still relevant)
Akira: These are the requirements currently:
1. Gimp 2.2.9
2. Python 2.4+
3. potrace (the backend; this is much better at tracing pixely stuff than autotrace*, but it only works on B/W pics. That is actually an advantage for my plugin.)
* autotrace is what the 'selection to path' plugin included in Gimp by default is based on.
optionally, my other plugins are helpful.
It will be faster on Linux, cause Linux has better startup times (due to excellent disk caching i think)
My plugin provides the following:
* a command to automatically vectorize the picture, with a vector for each color region
* the reverse, a command to automatically rasterize a set of vectors (the color is encoded in the name)
* also for nicety, a command that just wraps potrace and functions as a usually more likeable version of 'Selection to path'.
However
This is about the only of my many plugins that I am not prepared to give you yet. I need to sort out this patenting business first.
Technically I could prevent someone else from patenting just by having well distributed prior art (ie this plugin), but I am undecided yet as to the course I'll take.
