Draw circle into image

Parameters:

  • centre (array_like(2)) – centre coordinate (u,v)

  • radius (int) – circle radius in pixels

  • kwargs – parameters passed to draw_circle

Example:

>>> from machinevisiontoolbox import Image
>>> img = Image.Zeros(100)
>>> img.draw_circle((20,30), 15, color=200)
>>> img.disp()
<matplotlib.image.AxesImage object at 0x7f003d5aaa00>
>>> img = Image.Zeros(100, colororder="RGB")
>>> img.draw_circle((20,30), 15, color=[0, 200, 0], thickness=-1) # filled green circle
>>> img.disp()
<matplotlib.image.AxesImage object at 0x7f003d5455e0>
Note:

If the image has N planes the color should have N elements.
