Angular gradients in JGraphics

Hi there,

what's the best way to create angular gradients in JGraphics?
With angular gradients I mean color that smoothly fades according to a certain angle.

For instance, let's imagine to have a circle, of which 0 degrees is the topmost point and 90 degrees the rightmost point.
I would like a gradient that smoothly sweeps from 0 to 90 degrees.

This link might explain you better what I mean:

Does JGraphics offer a set way to do that like it happens for linear and radial gradients?

Any advice highly appreciated.

Thanks.

Hi,

You can do that in jgraphics. There is an example in uitester example in the latest SDK (mode 7, in the snippet_gradient() method).

HTH,

Thanks Emmanuel for your reply.

The uitester.c example shows how to create linear and radial gradients.

What I am asking is how to create angular gradients.

I think the best way to understand what I mean with angular gradients is to see a picture of it.

Please go to this site and scroll down to angular gradient:

I don't think an angular gradient example is anywhere in the SDK, but I would love to see a coded example for sure.

Thanks for any help.
