Intersect Function

Is there a function to determine the intersection point (x,y) of two lines? The intersect function in LC only gives me a true or false, and I need the exact location (x,y) of the intersection. Thanks, Beat ___ use-livecode mailing list

Re: Intersect Function

Thanks Craig, I was already afraid of that. Yes, I guess I could figure out the math. I will have the 2 functions of the lines and if I set them equal, I could solve the intersection point of the two. Your way is also valid, but as I need to determine many intersection points, the script might get

Get RGB color of a specific screen location
