Ah yes thanks for the hint. Now it works like intended. Thanks a lot.

It’s more like a javaScript manipulated drawing.

Example JsFiddle:
https://jsfiddle.net/7mvq29xa/1/

var canvas = document.getElementById("myCanvas");
    var c = canvas.getContext("2d");
    var startX = 50;
    var startY = 50;
    var endX = 100;
    var endY = 100;
    var amount = 0;
    setInterval(function() {
        amount += 0.05; 
        c.clearRect(0, 0, canvas.width, canvas.height);
        c.strokeStyle = "black";
        c.moveTo(startX, startY);
        c.lineTo(startX + (endX - startX) * amount, startY + (endY - startY) * amount);
        c.stroke();
    }, 30);

This works. Thank you much, sir!

oh okay thanks i’ll solve it with javascript then. Do you know how to use ‘in parent docs’ in javascript? I need to control a html-element in parent docs inside my listener.
