Not sure if this problem can only be solved by a script, but I need an arbitrary point to be moved to the origin. Without knowing the initial distance from the center, how to move the point TO the center?

I should have said polygon/ellipse/etc instead of point, but isn't a point really just an area or volume anyway in the real world, 0 dimensional, ha!

I would do it like this if radius was known. Twice as complicated if radius is not known, for you have to establish distance from both edges and average the result. (FF4)

Better methods very likely exist.

Oh the glory of the motion blur! Genius. Thank you.
 I'll see if I can stumble upon any better way._____________________________________________________

You may wanna try scripting part of it, namely finding the distance fr om the edges after the initial horizontal (or vertical) motion blur and threshold. Might improve the speed, as you would need to do it for just one horizontal row and column of pixels, wh ereas the motion blur is pretty calculation-intensive.
BTW, the same method can be used to remove all white area around the image for an automatic "scale-to-fit", and other things of that nature. |

Just used this technique for an isometric perspective walk through, and found that 7 is more accurate than 10 for the repeat on the gradient prior to blur. Must be that it is the closest prime number on the low side of 10. _____________________________________________________
