ellipse_arrays

laserbeamsize.image_tools.ellipse_arrays(xc_px: float, yc_px: float, d_major: float, d_minor: float, phi: float, npoints: int = 200) → ndarray[tuple[Any, ...], dtype[floating]]

Return x, y arrays to draw a rotated ellipse.

Parameters:

• xc_px – horizontal center of beam

• yc_px – vertical center of beam

• d_major – major axis (i.e, major diameter)

• d_minor – minor axis (i.e, minor diameter)

• phi – angle between major axis and horizontal axis [radians]

• npoints – (optional) number of points to use for ellipse

Returns:

x, y – two arrays of points on the ellipse
