Noise:

Transparent background:

Example usage

var img = new Image();
img.onload = function() {
	Pixastic.process(img, "pointillize", {radius:5, density:1.5, noise:1.0, transparent:false});
}
document.body.appendChild(img);
img.src = "myimage.jpg";

Parameters

• radius (int)
  Radius of the points, value greater than 1.
• density (float)
  Density of the points. Value from 0 to 5. A value of 1 gives a total of (width * height / diameter) points.
• noise (float)
  Noise in the distribution of the points, value equal to or greater than 0.
• transparent (bool)
  If true, the points will be painted on a transparent background, otherwise they are painted on top of the original image.

Known issues

• Since the points are painted in order top to bottom, left to right, a "layering" effect can be seen when using high densities.
