I have tried making a trigger variable, when it is equal to 1 then it should paint a rectangle using paintEvent.
First import required packages and create and black (512, 512, 3) image using numpy and crate functions to handle opencv events. Turtle has no built-in primitive for.
Syntax: cv2. . But we can draw rectangle to any images so - Try following piece of code.
Next argument is axes lengths (major axis length, minor axis length).

The rectangle extends from xy  to xy  + width in x-direction and from xy  to xy  + height in y-direction. With Qt, if you use QPainter.
ImageDraw module of the Python image processing library Pillow (PIL) provides many methods for drawing.
These two functions are used to enclose a set of Python Turtle commands that will draw a filled shape using the current fill color.
