Re: multi-colour gradient, dreadful banding
Are you saying that you are using IM 6.7.7.10 and you cannot use bicubic or get different results from what I posted? Do I misunderstand?Draoidh wrote:I'd love to but my sysadmin refuses to install anything that isn't in Debian. Debian sid (unstable) is up to IM 6.7.7.10-3.

Re: multi-colour gradient, dreadful banding
The latest greatest IM version I can get from Debian unstable is 6.7.7.10.
However, I tried 6.7.7.10 and I got totally different looking results with bicubic (see previous post).
Because of this, I went back to 6.7.7.2, which gives me banding with bicubic; but with bilinear I get a gradient that looks very similar to yours.

Re: multi-colour gradient, dreadful banding
I do not know what is/was happening with -interpolate bicubic. Anthony would have to comment.

Re: [SOLVED] multi-colour gradient, dreadful banding
If you like to remove the black banding between primary colors, do the gradient in either LAB or LUV colorspaces.
This preserves the intensity when generating gradients.

Re: [SOLVED] multi-colour gradient, dreadful banding
A new member posted, suggesting that "-spread 50" will reduce banding effects. This is true.

I've removed the post, but I'm in a generous mood so haven't also banned him. But if he posts again, advertising his products, I will.
