Re: [Gimp-user] Multicolor pinwheel effect.
Hi John, making the gradient match exactly the circle will be the tough bit, but there's a nice trick to doing something like this: 1. Create a square image 2. Make a gradient that you want to use (I created a gradient with red at both ends, and a HSV clockwise blend mode) 3. Blend fill your rectangle 4. Add a white to transparent gradient on the bottom for the center of your circle (otherwise it'll look funny) 5. Apply a 'polar coordinates' filter You should get a pinwheel effect. To change the pinwheel, you just need to change the gradient. Cheers, Dave. John R.

And I want the colors to blend into each other as in a gradient. A rainbow gradient is an obvious starting point. Would anyone like to suggest a sequence of tools to arrive at this effect? I will post this query elsewhere, but will not crosspost. -- David Neary [EMAIL PROTECTED] ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

Perhaps I need to put the gradient on a diagonal for this effect. I will experiment! I should mention that after I create the graphic I will select just a portion of it for the background. So the center is not critical. ___ Gimp-user mailing list Gimp-user@lists.XCF.Berkeley.EDU https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-user

Pinch and whirl to perfection afterwards. The tricky bit is getting the radial pattern.
