finding "distance" between two pixel's colors.
- by igor
Once more something relatively simple, but confused as to what they want.
the method to find distance on cartesian coordinate system is
distance=sqrt[(x2-x1)^2 + (y2-y1)^2]
but how do i apply it here?
//Requires: testColor to be a valid Color
//Effects: returns the "distance" between the current Pixel's color and
// the passed color
// uses the standard method to calculate "distance"
// uses the same formula as finding distance on a
// Cartesian coordinate system
double colorDistance(Color testColor) const;
