I read the Calculate Bounding box coordinates from a rotated rectangle to know how to calculate bounding box coordinates from a rotated rectangle. But in a special case as follow image: How to get the rotated rectangle size if had get the bounding box size, coordinates and rotate degree? I try write code in javascript //assume w=123,h=98,deg=35 and get calculate box size var deg = 35; var bw = 156.9661922099485; var bh = 150.82680201149986; //calculate w and h var xMax = bw / 2; var yMax = bh / 2; var radian = (deg / 180) * Math.PI; var cosine = Math.cos(radian); var sine = Math.sin(radian); var cx = (xMax * cosine) + (yMax * sine) / (cosine * cosine + sine * sine); var cy = -(-(xMax * sine) - (yMax * cosine) / (cosine * cosine + sine * sine)); var w = (cx * 2 - bw)*2; var h = (cy * 2 - bh)*2; But...the answer is not match w and h
