C# Class AForge.DoublePoint

Structure for representing a pair of coordinates of double type.

The structure is used to store a pair of floating point coordinates with double precision.

Sample usage:

// assigning coordinates in the constructor DoublePoint p1 = new DoublePoint( 10, 20 ); // creating a point and assigning coordinates later DoublePoint p2; p2.X = 30; p2.Y = 40; // calculating distance between two points double distance = p1.DistanceTo( p2 );
