The output image is the same as the Go version. This requires the module from the Grayscale image Task.

{{trans|Go}}

<lang d>import grayscale_image;

void main() {

enum order = 8,

margin = 10,

width = 2 ^^ order;

auto im = new Image!Gray(width + 2 * margin, width + 2 * margin);

im.clear(Gray.white);

foreach (y; 0 .. width)

foreach (x; 0 .. width)

if ((x & y) == 0)

im[x + margin, y + margin] = Gray.black;

im.savePGM("sierpinski.pgm");
