Dipping my feet into some more Core Graphics drawing, I'm attempting to recreate a wicked looking metallic knob, and I've landed on what is probably a show-stopping issue.
There doesn't seem to be any way to draw angle gradients in Core Graphics. I see there's CGContextDrawRadialGradient() and CGContextDrawLinearGradient(), but there's nothing that I see that would allow me to draw an angle gradient. Does anyone know of a workaround, or a bit of framework hidden away somewhere to accomplish this without pre-rendering the knob into an image file?
