vernier_scale

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

Create a Vernier scale.

Parameters:

  • 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:

Markers for each ruler as a tuple of 2 lists.

Return type:

tuple[list[Rectangle | Polygon], list[Rectangle | Polygon]]

scale_1um = vernier_scale(15, 10, 2)

scale_2um = vernier_scale(15, 10, 2, divider=5, gap=-2, triangular_marker=True)
