Making oval of fixed radius from the co-ordinates

[Viplav Abhiyan]

Hello all,

I am very beginner in ImageJ macros programing. I would like to know how can I make a oval shape of defined radius from the co-ordinates obtained from another macros in Image J.

I have used this macro for obtaining the co-ordinates:

if( s == -1 ) {
    exit("There was no selection.");
} else if( s != 10 ) {
    exit("The selection wasn't a point selection.");
} else {
    getSelectionCoordinates(xPoints,yPoints);
    x = xPoints[0];
    y = yPoints[0];
    showMessage("Got coordinates ("+x+","+y+")");

}

Now the question is how can I make a circle of defined radius using the co-ordinates (x, y). Please let me know. That would be really helpful.

Thanks, Best Regards, Abhiyan
