Method

doubledistance(double u, double v, double pu, double pv)
Returns the distance from point u,v to point pu,pv 
double du = pu - u;
double dv = pv - v;
dv = dv * dv;
du = du * du;
return Math.sqrt(dv + du);
doubledistance(double w1, double h1, double w2, double h2, int type)
Determina a distancia entre dois pixels 
if (type == 1) {
    return Math.sqrt(Math.pow(w1 - w2, 2) + Math.pow(h1 - h2, 2));
} else if (type == 2) {
    return Math.abs(w1 - w2) + Math.abs(h1 - h2);
} else {
    return Math.max(Math.abs(w1 - w2), Math.abs(h1 - h2));
doubledistance(double x, double y, double xx, double yy)
Calculate the Pythagorean distance from (x, y) to (xx, yy) 
double dx = xx - x;
double dy = yy - y;
return Math.sqrt(dx * dx + dy * dy);
doubledistance(double x0, double y0, double x1, double y1)
distance 
return Math.sqrt(distanceSquared(x0, y0, x1, y1));
doubledistance(double x0, double y0, double z0, double x1, double y1, double z1)
distance 
return Math.sqrt(distanceSq(x0, y0, z0, x1, y1, z1));
doubledistance(double x1, double y1, double x2, double y2)
distance 
double lat1 = Math.PI / 180.0 * x1;
double lat2 = Math.PI / 180.0 * x2;
double dLng = Math.PI / 180.0 * (y2 - y1);
double R = 3958.760;
return Math.acos(Math.sin(lat1) * Math.sin(lat2) + Math.cos(lat1) * Math.cos(lat2) * Math.cos(dLng)) * R;
doubledistance(double x1, double y1, double x2, double y2)
distance 
return Math.sqrt(Math.pow(x1 - x2, 2) + Math.pow(y1 - y2, 2));
doubledistance(double x1, double y1, double x2, double y2)
distance 
return Math.sqrt((x1 - x2) * (x1 - x2) + (y1 - y2) * (y1 - y2));
doubledistance(double x1, double y1, double z1, double x2, double y2, double z2)
distance 
return Math.pow(Math.pow((x2 - x1), 2) + Math.pow(y2 - y1, 2) + Math.pow(z2 - z1, 2), 0.5);
doubledistance(double xOrigin, double yOrigin, double xDestination, double yDestination)
distance 
double offsetX = xDestination - xOrigin;
double offsetY = yDestination - yOrigin;
return Math.sqrt(offsetX * offsetX + offsetY * offsetY);
