img pxl

Pxl pixelates into right-angled triangles. By default the “direction” of each triangle is determined by the “closeness” of the average colour in each quadrant.

--alias

Do not use antialiasing. If not using a square size this will make the result look bad.

--crop

Crop final image to exact triangles.

--left

Use only left triangles.

--right

Use only right triangles.

--cols <num>

Split into num columns.

--rows <num>

Split into num rows.

--size <HxW>

Specify the exact size to pixelate by (default: 20x20).
