Re: [ferret_users] inverting cmocean color bar

[saurabh rathore <rohitsrb2020@xxxxxxxxx>]

Thank you, Gert and Ryo for sharing the files and the command to invert it. I found PyFerret have cmocean color bars but recently cmocean have included more color palettes which are not in the PyFerret yet. So I was thinking to play with the cmocean color palettes and make the new additions compatible to PyFerret. I tried that but failed. May I know what are the steps to convert cmocean color palettes to pyferret compatible .spk file?

here is the link for the ferret spk files and the cmocean developer rgb files.

cheers, saurabh

I am using cmocean color bar and I like to plot the color bar in reverse direction means upside down. I tried a lot using Matlab also to flip it upside down but unsuccessful and too much of time-consuming. So is it possible to invert the colour the cmocean color bar like blue_orange to orange_blue?

I'm attaching my script which does that.

$ ruby ferret-invert-spk.rb your-rainbow.spk my-grayscale.spk . . .

I hope it works for you.

Cheers,

Ryo
