Example-1:
function setup() { // Create Canvas of given size createCanvas(380, 170); } function draw() { // Set the background color background(220); strokeWeight(12); //set strokeJoin function strokeJoin(ROUND); // rotation function rotate(PI / 10.0); line(20, 30, 200, 30); line(200, 30, 200, 100); line(200, 100, 20, 30); } |
Output:
Example-2:
function setup() { // Create Canvas of given size createCanvas(380, 170); } function draw() { // Set the background color background(220); strokeWeight(12); // rotation function rotate(PI / 7.0); textSize(30); text("GeeksForGeeks", 50, 50); } |
Output:
