To make a filled square or any shape in Python, set theĬv2. Unfilled square shown earlier is this square is the thickness parameter The only difference between this square and the other The longer answer: yes, BUT&mldr Let’s start by saying that viruses are a little bit anachronistic in 2021&mldr nowadays other kinds of malware (like worms for example) are far more common than viruses. With no dimensions changed from the first image, the only changeīeing that the interior is filled with color, this produces the following I was relaxing on a beach during my summer leave when I received a mail from a reader that asked me if it is technically possible to write a virus using Python.

Next, we show how to create a square whose interior is filled. In this case, it's 10, which is relatively thick In the last parameter, the fifth parameter, we specify the thickness
Since in this example our square is blue, Next, in the fourth parameter, we must specify the color of the square. In this example, to end at the point, (400,300). Pt2 represents the lower right border of the square. The third parameter we must specify is where the square ends. Then you can see the dimensions of where you want this image to start and end. If you're not sure where toīegin, show the blank image with grids first before beginning the square. In this example, to begin at the point, (100,200). Pt1 represents the upper left border of the square. The second parameter we must specify is where the square starts. This provides a perfect clean white background, in which we We will be using what we created with numpy, The first parameter that we must feed into the cv2.rectangle() function Next, we use the cv2.rectangle() function to create our We now have a blank image (like a canvass) in which we can now Next, we create a blank white image and store this in the Numpy (to create a blank image), and matplotlib (to get grided axes). It contains well written, well thought and well explained computer science and programming articles, quizzes and practice/competitive programming/company. Whiteblankimage = 255 * np.ones(shape=, dtype=np.uint8)Ĭv2.rectangle(whiteblankimage, pt1=(200,200), pt2=(300,300), color=(0,0,255), thickness=10)įirst, we import all the modules we need which is cv2 (OpenCV),

The code to create this square which is shown above is The square we will create is shown below. So the first type of square we will create is one where the One where the center is unfilled and one where the center is filled. In this article, we're going to create 2 types of squares,
To the right, middle, upper, lower, etc.). This includes its location (where it is on the blank image such as to the left, There are many parameters that go into the rectangle() function, whichĪllow us to control various aspects of it.
Is adequate and perfectly suited for creating a square shape. A square is a special kind of rectangle where each side is the same length. This is because Python's OpenCV module has no You may be wondering why we are using a rectangle() function to build a square. Then using OpenCV, we add our square shape. Python has a built-in rectangle() function, which allows us toĪdd a square to an image, usually a blank one. OpenCV allows a user to create a wide variety of shapes, including In this article, we show how to draw a square How to Draw a Square in Python using OpenCV
