Details

class Gegl.Random

classmethod new()

Return type:

Gegl.Random

Creates a new random number generator initialized with a random seed. This structure needs to be freed by the user with Gegl.Random.free();

classmethod new_with_seed(seed)

Parameters:

seed (int) – an integer seed, change for different permutation.

Return type:

Gegl.Random

Return an opaque structure associated to the seed. This structure needs to be freed by the user with Gegl.Random.free();

duplicate()

Return type:

Gegl.Random

Return a new copy of an existing Gegl.Random

float(x, y, z, n)

Parameters:

• x (int) – x coordinate

• y (int) – y coordinate

• z (int) – z coordinate (mipmap level)

• n (int) – number no (each x,y coordinate provides its own sequence of numbers

Return type:

float

Return a random floating point number in range 0.0 .. 1.0.

float_range(x, y, z, n, min, max)

Parameters:

• x (int) – x coordinate

• y (int) – y coordinate

• z (int) – z coordinate (mipmap level)

• n (int) – number no (each x,y coordinate provides its own sequence of numbers

• min (float) – minimum value

• max (float) – maximum value

Return type:

float

Return a random floating point number in the range specified, for the given x,y coordinates and Gegl.Random provided, if multiple different numbers are needed pass in incrementing n’s.

free()

Free a Gegl.Random structure created with Gegl.Random.new() or Gegl.Random.new_with_seed()

int(x, y, z, n)

Parameters:

• x (int) – x coordinate

• y (int) – y coordinate

• z (int) – z coordinate (mipmap level)

• n (int) – number no (each x,y coordinate provides its own sequence of numbers

Return type:

int

Return a random integer number in range 0 .. MAX_UINT

int_range(x, y, z, n, min, max)

Parameters:

• x (int) – x coordinate

• y (int) – y coordinate

• z (int) – z coordinate (mipmap level)

• n (int) – number no (each x,y coordinate provides its own sequence of numbers

• min (int) – minimum value

• max (int) – maximum value+1

Return type:

int

Return a random integer point number in the range specified, for the given x,y coordinates and Gegl.Random provided, if multiple different numbers are needed pass in incrementing n’s.

set_seed(seed)

Parameters:

seed (int) – an integer seed, change for different permutation.

Change the seed of an existing Gegl.Random.
