w – frame width, h – frame height

Note

  • If h and w values are more than size of original frame, the frame will be received with original size.
  • Zooming out of width and height is available only discretely – in 2, 4, 8 times, etc. If specified sizes are not corresponding to 1/2, 1/4 etc. of original frame size, the frame will be received with size divisible by the original frame size close to specified values.
