Making an image persist when its animation ends
Sometimes an image should stay at its endpoint. This demo illustrates one way to accomplish that.

Animation test;

void setup()
{
  size(400,100);
  
  test = new Animation(this, loadImage("image.gif"), 100,40, 200,40);
  test.setRepetitions(1);
  test.setEnd("endMethod");
  test.showRectangle();
  test.setDuration(10000);
}

void loop()
{
  background(127);
  test.draw();
}

// alter the Animation so that it makes a linear path in a rectangle
// with width and height 0.
void endMethod()
{
  test.setRectangle(test.currentX(),test.currentY(),0,0);
  test.setRepetitions(0);
  test.reset();
}
