Calculate rotated bounding box size

rotatedBBoxSize.ts

export function rotateSize(width: number, height: number, rotation: number): { width: number, height: number } {
  const rotRad = (rotation * Math.PI) / 180

  return {
     width: Math.abs(Math.cos(rotRad) * width) + Math.abs(Math.sin(rotRad) * height),
     height: Math.abs(Math.sin(rotRad) * width) + Math.abs(Math.cos(rotRad) * height),
   }
 }
