RandomImage

gives an image of dimensions

with pseudorandom pixel values generated from a uniform distribution in the range 0 to max.

generates pixel values using a uniform distribution in the range min to max.

generates pixel values using a symbolic distribution dist.

RandomImage by default does not assign a specific color space to the image. The color space of the resulting image can be specified using the ColorSpace option.

Generate a random image:

Generate a random image with values in the upper quartile:

Generate an image of Laplacian noise:

A random image where the first two channels are correlated:

Generate an RGB image simulating salt-and-pepper noise using a heavy-tail distribution:
