Parameters:

• rho (float) – Offset coordinate.

• theta (float) – Angle coordinate in degrees.

• sz (tuple of int) – Size of image in (ny, nx). Streak endpoints will be truncated at the images edges.

Returns:

pos – Array with form [p0, p1] where each p is (x, y), the x and y coordinates of each end.

Return type:

array
