Canvas it's a simple class that I use as my startup for personal projects in Canvas Javascript.
To use just instance the Canvas class, and use the draw method to pass what you want.
window.onload = function () {
var canvas = new Canvas();
canvas.draw(function (canvas) {
canvas.context.fillStyle = 'rgb(0, 0, 0)';
canvas.context.fillRect(0, 0, canvas.width, canvas.height);
console.log(canvas.context, canvas.width, canvas.height, canvas.c_width, canvas.c_height);
});
};The properties of canvas parameter in draw callback are:
- canvas
- context
- width
- height
- c_width (center width)
- c_height (center height)
