Usage? :)

[ser]

Hi, maybe I am doing something wrong, but I have this:

<script src="fractal.js" type="text/javascript"></script>
<script type="text/javascript">
  var fractal = new Fractal(document.getElementById("frac1"));
</script>

and dev console says:

(index):227 Uncaught ReferenceError: Fractal is not defined

Where is my fault? :)

It’s under the window.mandelbrotFractal.Fractal namespace.

Hi, thanks, I have rewritten my invocation, but still have errors.

<script src="fractal.js" type="text/javascript"></script>
<script type="text/javascript">
  var fractal = new window.mandelbrotFractal.Fractal(document.getElementById("frac1"));
</script>

and dev console says:

Uncaught TypeError: canvas.getContext is not a function

Where is my fault? :)

Not sure... you need to make sure the frac1 element is a canvas element, like https://github.com/rafgraph/fractal/blob/gh-pages/index.html#L51

OK, it works now! Thanks for a hint :) :)

I had

<img id="xxx">

instead of

<canvas id="xxx"></canvas>

One more question. You have a few screenshots on README.md - what are required parameters to get them? Have you experimented a way to get a random fractal?

Don’t know... the maxEscapeTime Was probably 896 or 1792. They were created using https://fractal.rafgraph.dev
