        inner class RotateCircleCrop : CircleCrop() {

                pool: BitmapPool,
                toTransform: Bitmap,
                outWidth: Int,
                outHeight: Int
            ): Bitmap {
                Log.d(TAG, "$outWidth $outHeight ${toTransform.byteCount}")
    
                //先变换成圆形图。
                val bmp = TransformationUtils.circleCrop(pool, toTransform, outWidth, outHeight)
    
                //再逆向旋转30度。
                return TransformationUtils.rotateImage(bmp, -30)
            }
        }
    }

正常的摆放：
