HI guys, I am trying to add another type of atom in the GAFF parameter file that is called during the minimization process and can't find the right place.

Hi Ludovic,
This is possible, but a little tricky. It requires writing Python code. So if I were to code a solution (and I may if you don't, but I need to fix a few bugs first), I'd make a chimera extension that would load an image into an OpenGL texture, then in the 2D drawing pass, I'd draw it underneath everything that is currently drawn. The reason for using a texture instead of a bitmap is to allow for high resolution backgrounds for saving images.
If you are inclined to write this yourself, code for a chimera extension that does OpenGL in Python can be found in the CHIMERA/share/Ilabel package.

Hi,
I would like to know if its possible to use a PIL or a raw image as a background image. And/Or can you help me figure out how to do it (maybe using some volume from image functinoality). Ideally, I would like to be able to update in realtime this background image (either using a thread, or a callback)
Hi Ludovic, The developer who could authoritatively answer your question (Greg Couch) is out this week, so I'll take a stab at it: I don't think so. :-) However, if your goal is to, say, make a movie with a background you provide then you could write out image files with a transparent background (described in this message: http://www.cgl.ucsf.edu/pipermail/chimera-users/2008- January/002197.html) <http://www.cgl.ucsf.edu/pipermail/chimera-users/2008- January/002197.html%29> and use most any image-processing program to compose the Chimera images with the background(s) you prefer. Despite my flippant answer in the first sentence, I don't really know if it is possible to directly change the background. When Greg gets back I hope he will comment on that. Perhaps you could say more about what your ultimate goal is?

Hi Ludovic,
Everything is possible.
