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.
