@ -26,9 +26,12 @@ Here you can see the phases of building a clock hand: source shape, resize shape
hand.setScale(.08,.8); //scale down the width to .08 and also shorten the hand with a facor of .8
hand.setPivot(0,pivy); //set the pivot point
```
Now its time to rotate the hand to the desired position. Lets assume, we want to show the hour hand for 5:40:05, we have to rotate about 170 degrees. After then we can draw the hour hand with one of the drawing method of TFTShape.
