It was presented by some folks from INRIA, Grenoble U, U of Washington and Adobe. They seem to be talking about much the same thing as what you have been talking about and have similar observations about the limitations of more "primitive" gradients. It starts with a cubic bezier and then allows color gradients on either side, together with a set of blur control points that control the transitions between the two halves. They also have come up with a way of computing all this in a practical way, that looks very promising.

I was trying to make contact with all of authors, listed in quoted article. One answerd me once: >Hi Andrew, >indeed, your work seems to be very similar to ours!

No matter what efficient solutions I offer, the real use will be only if at last one vector file format will be expanded. Well, I'll inform this group when the next version of my converter is complete to testing. Currently I have some problems with preserving original colors during resizing. regards, A
