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).
Best regards,
Jesper

The colorbar returns a Colorbar object, the "solids" attribute of which is a Quadmesh; so you should be able to execute
cbar.solids.set_antialiased(False)
to turn off antialiasing. With a bit of testing, however, I am not seeing any difference, so I'm not sure what is going on, and I don't have time now to investigate.

Hi Eric
Thanks for your reply and sorry for my late response. Thanks for the pointer. I will try to investigate the issue myself.
