scale

K.scale(x: number, y: number): void

Scales the current coordinate system. This is the native Canvas 2D method, so both arguments are required.

K.push();
K.scale(2, 2); // uniform 2× scale
K.circle(50, 50, 20);
K.pop();

For uniform animated scaling, compute once and pass the value twice:

const amount = 1 + Math.sin(K.time * 2) * 0.25;
K.push();
K.translate(K.width / 2, K.height / 2);
K.scale(amount, amount);
K.circle(0, 0, 40);
K.pop();

Use different values for non-uniform scaling:

K.scale(2, 0.5);

Scaling accumulates with the current transform. Use K.push()/K.pop() to isolate it. Negative values mirror the coordinate system.
