Re: [Matplotlib-users] Antialiasing colorbars
Hi Eric Thanks for your reply and sorry for my late response. Thanks for the pointer. I will try to investigate the issue myself.

[Matplotlib-users] Antialiasing colorbars
Hi matplotlib users, Is it possible to disable antialiasing for a colorbar? If not directly is it the possible to postprocess the axes instance to se antialiasing for relevant elements? The reason I am asking is because I would like to produce a paletted png (using PIL) of the colorbar without the risk of removing any important colors in the process (in essence the output from matplotlib needs to have less than 256 colors for this to work).
