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 With no dimensions changed from the first image, the only changeīeing that the interior is filled with color, this produces the following

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. Keyloggers are one of the most common tools in a Hacker's toolbox. In this example, to begin at the point, (100,200). Today we're going to work on building a Python Keylogger. 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 Data can then be retrieved by the person operating the. We will be using what we created with numpy, Keystroke logging, often referred to as keylogging or keyboard capturing, is the action of recording (logging) the keys struck on a keyboard, 1 typically covertly, so that a person using the keyboard is unaware that their actions are being monitored. 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). 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
