I wonder if angle gradient is possible

Question

I´m doing some testing on gradients using NSBezierPath and make some progress so far with radial gradients. see first picture. I wonder, however, if it is possible to make angle gradients as in picture 2.

Anyone done this?

Answer 1

Cocoa has no public API for angular gradients. You'll have to do it yourself by painting pixels in varying colors.

Answer 2

Good Question! There is no Standard Feature. Try to approx by dividing the Circle into sectors which functions as clipping Polygon Then draw a linear Gradient in direction 90 degrees to the Center line of the sectors.
