code: public static Point2D_F32 convertNormToPixel(CameraModel param , float x , float y , Point2D_F32 pixel ) {
  		return ImplPerspectiveOps_F32.convertNormToPixel(param, x, y, pixel);
  	}
docs: <p>
  Convenient function for converting from normalized image coordinates to the original image pixel coordinate.
  If speed is a concern then {@link PinholeNtoP_F64} should be used instead.
  </p>
  
  @param param Intrinsic camera parameters
  @param x X-coordinate of normalized.
  @param y Y-coordinate of normalized.
  @param pixel Optional storage for output.  If null a new instance will be declared.
  @return pixel image coordinate
