stencil.vernier_scale

vernier_scale(
    unit,
    marker_length,
    marker_width,
    divider=10,
    gap=0,
    triangular_marker=False,
)

Create a Vernier scale.

Args

• unit (float): Distance between markers in the main scale.
• marker_length (float): Length of the scale markers.
• marker_width (float): Width of the scale markers.
• divider (int): Divider used for the secondary scale. The Vernier constant will be unit / divider (scale readability).
• gap (float): Distance between the main and secondary scales.
• triangular_marker (bool): Flag indicating the use of triangular markers.

Returns

tuple[list[Rectangle | Polygon], list[Rectangle | Polygon]]: Markers for each ruler as a tuple of 2 lists.

Example

>>> scale_1um = pf.stencil.vernier_scale(15, 10, 2)
>>> scale_2um = pf.stencil.vernier_scale(
...     15, 10, 2, divider=5, gap=-2, triangular_marker=True
... )
>>> scale_2um = [[s.translate((0, -40)) for s in part] for part in scale_2um]
>>> component = pf.Component().add(
...     "WG_CORE", *scale_1um[0], *scale_2um[0], "SLAB", *scale_1um[1], *scale_2um[1]
... )
