Function Documentation

def perlin_noise.int_perlin_noise	(		width,
			height,
			layers,
			n,
			tiles = 1
	)

Generates integer Perlin noise in a rectangle.

Parameters:

	width	The width of the rectangle.
	height	The height of the rectangle
	layers	The number of layers of smooth noise to use.
	n	The integer range for the resulting noise. If n is 7, for example, all values in the grid will be 0, 1, 2, 3, 4, 5, or 6.
	tiles	The number of tiles to generate. These tiles will all tile with themselves and each other.

def perlin_noise.make_uniform_noise	(		width,
			height
	)

Generates a Grid with uniform noise, generated between 0 and 1.

Parameters:

	width	The width of the Grid to produce.
