## Mathematic Functions for Graphic Program

I'd like to know if someone has a Mathematic Functions for Graphic Program, for exemplo : Distance of two points, Mouse over the Line, endpoint of line, middle point of line, ........

Thanks a lot !

## Re:Mathematic Functions for Graphic Program

I believe these functions are very simple, for example, point-point
distance:
D:=Hypot(x2-x1,y2-y1);
etc

## Re:Mathematic Functions for Graphic Program

For mouse over line, you can use a routine that calculates distance from a
point to a line, see here:

You can adapt it to do the other things too.

If you want a multipurpose library for screen objects, I advise
FlexGraphics.
