Will support transform BGR to RGB for 3-channel images? #1

Hi mediapy team!

Thanks for sharing this awesome tool. It seems that the color map only support grey to RGB currently. Because opencv uses BGR by default and it's also widely used. I want to know if there are some plans to support this channel mode, and if this mode is already supported, could you give me some hints where this interface is?

Could you please give an example? The function to_rgb() returns a numpy array with RGB channels, so to_rgb()[..., ::-1] would give BGR channels.

Given a BGR image array, one can operate on it as an RGB image using array[..., ::-1]. Hope that helps.

Hi @hhoppe

Thanks for your quickly reply, it sounds reasonable to me! Use array[..., ::-1] instead can solve this problem.

My initial thought was through a parameter to address this situation automatically like following

media.show_image(array, border=True, cmap='rgb', height=400)
