rotated_rect_arrays

laserbeamsize.image_tools.rotated_rect_arrays(xc, yc, dx, dy, phi, mask_diameters=3)[source]

Return x, y arrays to draw a rotated rectangle.

Parameters:

  • xc – horizontal center of beam

  • yc – vertical center of beam

  • dx – ellipse diameter for axis closest to horizontal

  • dy – ellipse diameter for axis closest to vertical

  • phi – angle that elliptical beam is rotated [radians]

Returns:

x, y – two arrays for points on corners of rotated rectangle
