[Solved]how to rotate an arc about one end ?

blyk

Can anyone suggest me how to rotate the arc about the red dot ? Run it your would see the red dot

void setup() {
  size(400, 400);
}
int i=0;
void draw() {
  background(-1);
  // ellipseMode(RADIUS);
  translate(mouseX, mouseY);
  noFill();
  stroke(0);  
  strokeWeight(20);
  rotate(radians(i));
  arc(0, 0, 100, 100, 0, PI-PI/9);
  fill(255, 0, 0);
  noStroke();
  ellipse(50, 0, 10, 10);
  i++;
}

PhiLho

Just add translate(-50, 0); before the call to arc().

int angle=0;

void setup() {
  size(400, 400);
}

void draw() {
  background(255);

  translate(mouseX, mouseY);

  noFill();
  stroke(0);  
  strokeWeight(20);
  rotate(radians(angle));
  arc(0, 0, 100, 100, 0, PI-PI/9);

  fill(255, 0, 0);
  noStroke();
  ellipse(0, 0, 10, 10);

  angle++;
}
