function – to apply (add padding, grating couplers).
kwargs – for pack.

Keyword Arguments:

spacing – Minimum distance between adjacent shapes.
aspect_ratio – (width, height) ratio of the rectangular bin.
max_size – Limits the size into which the shapes will be packed.
sort_by_area – Pre-sorts the shapes by area.
density – Values closer to 1 pack tighter but require more computation.
precision – Desired precision for rounding vertex coordinates.
text – Optional function to add text labels.
text_prefix – for labels. For example. ‘A’ for ‘A1’, ‘A2’…
text_offsets – relative to component size info anchor. Defaults to center.
text_anchors – relative to component (ce cw nc ne nw sc se sw center cc).

spacing – between adjacent elements on the grid, can be a tuple for different distances in height and width.
separation – If True, guarantees elements are separated with fixed spacing if False, elements are spaced evenly along a grid.
shape – x, y shape of the grid (see np.reshape). If no shape and the list is 1D, if np.reshape were run with (1, -1).
align_x – {‘x’, ‘xmin’, ‘xmax’} for x (column) alignment along.
align_y – {‘y’, ‘ymin’, ‘ymax’} for y (row) alignment along.
edge_x – {‘x’, ‘xmin’, ‘xmax’} for x (column) (ignored if separation = True).
edge_y – {‘y’, ‘ymin’, ‘ymax’} for y (row) (ignored if separation = True).
rotation – for each component in degrees.
h_mirror – horizontal mirror y axis (x, 1) (1, 0). most common mirror.
v_mirror – vertical mirror using x axis (1, y) (0, y).
