/**
 * Kotlin method for Bitmap scaling
 * @param bitmap the bitmap to be scaled
 * @param pixel  the target pixel size
 * @param width  the width
 * @param height the height
 * @param max    the max(height, width)
 * @return the scaled bitmap
 */
fun scaleBitmap(bitmap:Bitmap, pixel:Float, width:Int, height:Int, max:Int):Bitmap {
    val scale = px / max
    val h = Math.round(scale * height)
    val w = Math.round(scale * width)
    return Bitmap.createScaledBitmap(bitmap, w, h, true)
  }
