Nim standard PRNG is an implementation of the <code>xoroshiro128+</code> (xor/rotate/shift/rotate) algorithm which is extremely fast. The standard library provides a Mersenne Twister implementation too. For this task, we used the first one.

<lang Nim>import random

import imageman

const Size = 500

randomize()

var image = initImage[ColorRGBU](Size, Size)

for x in 0..<Size:

for y in 0..<Size:

let color = ColorRGBU([rand(255).byte, rand(255).byte, rand(255).byte])

image[x, y] = color

image.savePNG("prng_image.png", compression = 9)</lang>
