Remarks

This command is available in the Document/Medical Imaging editions toolkits.

Scrambling a rectangular area means that the pixels in that area are shuffled around into a pseudo-random location within the area.

  • No colors are introduced
  • Color counts remain unchanged

Given the same encrypt area (defined by ScrambleCommand.Rectangle) and the same ScrambleCommand.Key, setting ( ScrambleCommand.Flags = ScrambleCommandFlags.Encrypt) is the inverse of (ScrambleCommand.Flags = ScrambleCommandFlags.Decrypt).
