primitive.js

A JavaScript re-creation of the primitive.lol application.

This project works on the ondras/primitive.js, and you can learn more about primitive.js in primitive.js

What is the difference between this project and ondras/primitive.js

This project works on the ondras/primitive.js, adding some features to that.

• rotatable rectangle
• bezier and straight line
• heart shape
• shapes cache exported by pre-calculating
• packed by rollup.js and provide some interfaces used by your program
• no svg

Example Usage

npm install Easonzero/primitive

// require the library will define a primitive `global`
require ('primitive')
let image = 'test.jpg';
let cfg = primitive.DefaultConfig();
// declare the type of shapes our drawing will use:
cfg.shapeTypes = [
  primitive.ShapeMap.Bezier, 
  primitive.ShapeMap.Rectangle, 
  primitive.ShapeMap.Triangle, 
  primitive.ShapeMap.Ellipse, 
  primitive.ShapeMap.Heart, 
  primitive.ShapeMap.Line 
]
cfg.shapes = 500
primitive.Pure(image, cfg).then(function(ori){
	let optimizer = new primitive.Optimizer(ori, cfg);
	let dst = primitive.Canvas.empty(cfg);
	// select element to append the canvas to
	document.querySelector("#result")!.innerHTML = "";
	document.querySelector("#result")!.appendChild(dst.node);
	// draw on dst.node canvas on each step
	optimizer.onStep = function (step){
		console.log('onStep', step);
		dst.drawStep(step);
	}
	// drawing finished
	optimizer.onEnd = function (state){
		console.log('onEnd', state);
	}
	optimizer.start();
});
