  • Modular usage (Area render)

After installation, you can import this as module.

There is only one API, use it as below:

import CanvasNest from 'canvas-nest.js';

const config = {
  color: '255,0,0',
  count: 88,
};

// Using config rendering effect at 'element'.
const cn = new CanvasNest(element, config);

// destroy
cn.destroy();

Configuration

  • color: color of lines, default: '0,0,0'; RGB values: (R,G,B).(note: use ‘,’ to separate.)
  • pointColor: color of points, default: '0,0,0'; RGB values: (R,G,B).(note: use ‘,’ to separate.)
  • opacity: the opacity of line (0~1), default: 0.5.
  • count: the number of lines, default: 99.
  • zIndex: z-index property of the background, default: -1.

Example:

  • Script tag
<script type="text/javascript" color="0,0,255" opacity='0.7' zIndex="-2" count="99" src="dist/canvas-nest.js"></script>
  • Modular usage (Area render)

{
  color: '0,0,255',
  opacity: 0.7,
  zIndex: -2,
  count: 99,
};

Note: If the Configuration isn’t customized, default values are available as well.
