Draw Geometrical Shapes by Dragging Mouse (Events) using OpenCV - Part 2

This video titled "Draw Geometrical Shapes by Dragging Mouse (Events) using OpenCV - Part 2" explains and showcases how to draw various geometric shapes like square, circle, rectangle etc. with Mouse Dargging (Event) using Python OpenCV. One can see how rectangle can be drawn with click on the left button and then dragging it to complete the shape. This is the fifth video in the the Python OpenCV Crash Course. Later on in the upcoming videos we will see how can we build face detection, object detection types of Computer Vision Projects.

Trivia Question from the video: What do variables
ix and iy signify in the Code we saw in the video?

[ganeshram]

ix, iy initialize the coordinates of the rectangle

[aditimondal]

Why the coordinates of the mouse is in imaginary plane?

[Dontmadder]

how can i do the same thing as a screenshot?

Hello Sir
Nice Video.

But when i am drawing rectangle with some thickness say 2 i am getting multiple rectangles but i want only one final rectangle.
The code I am using is same as yours for drawing the rectangle.

Please Suggest something to solve this.

Thanks in advance.
