Method pixelDensity

src/image/p5.Image.js:47–74

* Gets or sets the pixel density for high pixel density displays. * * By default, the density will be set to 1. * * Call this method with no arguments to get the default density, or pass * in a number to set the density. If a non-positive number is provided, * it defaults to 1.

(density)

   * @returns {Number} The current density if called without arguments, or the instance for chaining if setting density.
