KineticJS mouse position of image

I have a image like this

var image = new Kinetic.Image({
            x : x,
            y : y,
            width : 1000,
            height :100,
            image : image,
});

How do I get the mouse position based on the image. according this example, I could get position Object{0, 0} ~ {100, 1000}

I only found an api stage.getPointerPosition()

Solution

If you want to get mouse position on click then you can do this:

image.on('click', function(){
    var mousePos = youStage.getPointerPosition();
    var p = { x: mousePos.x, y: mousePos.y }; // p is a clone of mousePos
    var r =  image.getAbsoluteTransform().copy().invert().point(mousePos);
});

Please find the working example below albeit it uses KonvaJS but the concept is same. And you should also start using Konva cause it's well maintained and documented.

      yoda.on('click', function() {
        var mousePos = stage.getPointerPosition();
        var p = {
          x: mousePos.x,
          y: mousePos.y
        }; // p is a clone of mousePos
        var r = yoda.getAbsoluteTransform().copy().invert().point(mousePos);
        console.log(r);
      });
      // add the shape to the layer
      layer.add(yoda);
      // add the layer to the stage
      stage.add(layer);
    };
    imageObj.src = 'https://upload.wikimedia.org/wikipedia/en/thumb/9/9b/Yoda_Empire_Strikes_Back.png/220px-Yoda_Empire_Strikes_Back.png';
