Functions

rotate_image(original, x0, y0, phi)	Create image rotated about specified centerpoint.
axes_arrays(xc, yc, dx, dy, phi[, ...])	Return x, y arrays needed to draw semi-axes of ellipse.
ellipse_arrays(xc, yc, dx, dy, phi[, npoints])	Return x, y arrays to draw a rotated ellipse.
major_axis_arrays(image, xc, yc, dx, dy, phi)	Return x, y, z, and distance values along semi-major axis.
minor_axis_arrays(image, xc, yc, dx, dy, phi)	Return x, y, z, and distance values along semi-minor axis.
rotated_rect_arrays(xc, yc, dx, dy, phi[, ...])	Return x, y arrays to draw a rotated rectangle.
create_test_image(h, v, xc, yc, dx, dy, phi)	Create a 2D test image with an elliptical beam and possible noise.
crop_image_to_rect(image, xc, yc, xmin, ...)	Return image cropped to specified rectangle.
crop_image_to_integration_rect(image, xc, ...)	Return image cropped to integration rectangle.
