Remarks

  • The width of the scratches is 1 pixel. The length of the scratches is random (between 2 and MaximumScratchLength).
  • The size of the dust particles is 1 pixel (1x1).
  • The size and shape of pits is selected at random. The pit shapes are random and will be between 1x1 and MaximumPitSize x MaximumPitSize.
  • The command will also make random changes to the pixel’s intensities.
  • This command does not support signed data images.
