Let's make a image example with noise 2D:
from opensimplex import OpenSimplex
from PIL import Image
height = int(input("Enter in the map height: "))
width = int(input("Enter in the map width: "))
def main():
simplex = OpenSimplex()
im = Image.new('L', (width, height))
for y in range(0, height):
for x in range(0, width):
value = simplex.noise2d(x , y )
color = int((value + 1) * 128)
im.putpixel((x, y), color)
im.save('noise2d.png')
im.show()
if __name__ == '__main__':
main()
