var CanvasBuffer = function (width, height, options) {
    this.width = width;
    this.height = height;

    this.canvas = document.createElement('canvas');
    this.context = this.canvas.getContext('2d', options);

    this.canvas.width = width;
    this.canvas.height = height;
};

CanvasBuffer.prototype.constructor = CanvasBuffer;

CanvasBuffer.prototype.clear = function () {
    this.context.setTransform(1, 0, 0, 1, 0, 0);
    this.context.clearRect(0, 0, this.width, this.height);
};

CanvasBuffer.prototype.resize = function (width, height) {
    this.width = this.canvas.width = width;
    this.height = this.canvas.height = height;
};

export { CanvasBuffer };
