[Chimera-users] Printing on white background

When mapping protein residues around a ligand I would like to have a printout of the enlarged binding site area, so as to put remarks by pencil on the printout. However, on a white background, in order to save ink. Is that a problem of working out the image (I have Gimp only, of which I never gained expertise), or can Chimera provide directly?
