Affinity Photo--Polar filter

[ROYGBV]

Please introduce some more flexibility / customization options to this filter. It can be a very powerful filter, if all the parameters are controllable.

Also if anyone remembers Kai's power tools, (A plug in for Photoshop from the late 1990s early 2000s) it had very interesting filters, some that were quite similar, namely polar vortex. Also the filters would update, a controllable live preview before committing to the result. This made them superior to the native filters at that time. Photoshop actually had a rather low standard, and set a low bar, as regards creativity. They were (& are?) primarily geared toward producing images for mass media consumption. It was (& may still be so) that the plug in creators made the program a more creative program, by bringing such things as fractals, and tiling with the 17 wall paper groups, into the picture. I will post some images soon. I hope you find these ideas helpful. The plug in designers were brilliant & creative people and a study of their work would seem to be a good source for further development, and surpassing much of what is currently available. Unfortunately as Operating systems & hardware platforms constantly changed, simply constantly updating existing plugins, was apparently not interesting enough, and some great work was, as of now lost.
