Image.draw_point#

Image.draw_point(pos: tuple[int, int] | ndarray, marker: str = '+', text: str | None = None, **kwargs: Any) → None[source][source]#

Draw a marker in image

Parameters:

  • pos (array_like(2), ndarray(2,n), list of 2-tuples) – position of marker

  • marker (str, optional) – marker character, defaults to “+”

  • text (str, optional) – text label, defaults to None

  • kwargs – parameters passed to draw_point

Example:

>>> from machinevisiontoolbox import Image
>>> img = Image.Read("monalisa.png")
>>> img.draw_point((270,194), "+", "eye", fontsize=1, color="yellow")
>>> img.draw_point((293,246), "*", "nose", fontsize=1, color="blue")
>>> img.disp()

Note

If image has multiple planes then color should have the same number of elements as the image has planes. If it is a scalar that value is used for each color plane. For a color image color can be a string color name.

Warning

The image is drawn into in place, see draw_box for the requirement that the pixel data is C-contiguous.
