gdsfactory.read.from_np#
- gdsfactory.read.from_np(ndarray: ndarray, nm_per_pixel: int = 20, layer: tuple[int, int] = (1, 0), threshold: float = 0.99, invert: bool = True, border_pad_num_pixels: int = 2, border_pad_pixel_value: float | None = None) Component[source]#
Returns Component from a np.ndarray.
Extracts contours skimage.measure.find_contours using threshold.
- Parameters:
ndarray – 2D ndarray representing the device layout.
nm_per_pixel – scale_factor.
layer – layer tuple to output gds.
threshold – value along which to find contours in the array.
invert – invert the mask.
border_pad_num_pixels – number of pixels to pad image border with. A value of 2 is usually sufficient to capture contours along the image border.
border_pad_pixel_value – set value of padding pixels (optional). This is passed to np.pad through the ‘constant_values’ argument.
