Fields

Position: TEdgePosition;

If Position = epFirst, this is a vertex of the TScreenObject or this point is at the edge of the grid and this is the first spot where the TScreenObject intersects the grid (or else the contour has left the grid and is just reentering it)

If Position = epLast, this is a vertex of the TScreenObject or this point is at the edge of the grid and this is where the TScreenObject is exiting the grid.

If Position = epMiddle, this point is in the interior of the grid and this point is at the edge of an element or cell.

See TEdgePosition.

X: real;

X is the X-coordinate of the point.

Y: real;

Y is the Y-coordinate of the point.
