t value calculation from a point position with known XY axis on a Bezier curve

Hi here

In Illustrator, for an existing cubic Bezier curve, if I select one point on the path , how could I calculate the t value using Script?

In theory, there should be more less one answer. I did some sketch paper job how couldn't figure out easily.

Please help.

Thanks

Kevin

Actually, it will be a task of calculating a parameter of a point on a curve closest to a certain point.

A way to do this can be found at the following site.

Or perhaps you already know this method and may be looking for a simpler or more efficient way.

I would also like to know it if it exists.

Hi Sato san

Yes I am heading to the iterative methods as you told, to find the closed t point with the tolerance of distance.

BTW, I learned a lot with your previous posts about Scripting.

Thanks a lot
