Remarks

  • This method uses a pseudo-random number generator in order to create a Perlin noise, and then procedurally transforms that noise into a texture. Depending on the flags that are set, the texture can be saved as an image by itself, or the texture can be combined with another image.
  • This method is similar to the CloudsCommandBitmapEffect in that they both use Perlin equations to generate pseudo-random noise, but each method applies different equations to the noise to produce the texture.
  • Use the AddNoiseCommandBitmapEffect in order to add random noise to an image.
  • This command does not support signed data images.
