+this.canvas.getContext('2d').fillStyle = '#ffffff'; // The color of the text you are going to be displaying
+this.canvas.getContext('2d').font = 'bold ' + (24) + 'pt Arial'; // Pattern: weight [size]size_unit font_name
+this.canvas.getContext('2d').textAlign = 'center';
+this.canvas.getContext('2d').textBaseline = 'middle';
