recuperer tous les points (X,Y) d'un dessin

Bonjour :)

Alors j'ai dessiner 8 lignes partant d'un seul point ( 4 lignes droite et 4 ligne en forme d'un cercle) je veux recuperer tous les point ainsi leur cordonnées x y de chaque lignes et les mètrent dans une liste , quelqu'un aurait une idée s'il vous plait

   int margin = 100;
        int margin1 = 300;
        int top = 0 + margin;
        int bottom = canvas.getHeight() - margin;
        int left = 0 + margin1;
        int right = canvas.getWidth() - margin1;
        int centerX = x / 2;
        int centerY = y / 2;
        canvas.drawCircle(x / 2, y / 2, 50, paint1);
 
        canvas.drawLine(x/2,y/2,x/2,top,paint1);
        canvas.drawLine(x/2,y/2,x/2,bottom,paint1);
        canvas.drawLine(x/2,y/2,right,y/2,paint1);
        canvas.drawLine(x/2,y/2,left,y/2,paint1);
