Hi Ryo,

Thanks a lot for your effort.

Still, I'm thinking there should be some option in a ferret to make such kind of projection.

Best regards

I want something like this, please have a look at the attached figure.

I see! I don't know if it's possible on Ferret. I would modify the image using another tool such as Gimp and Imagemagick. "Perspective distortion" or "perspective projection" is what you are looking for, I think. For example,
