In Word documents, you may be introducing various terms, thoughts, or data. How to Insert a Line in Microsoft Word Documents shape can also be applied to see if the image is grayscale or color image. Please note that if we read the image in grayscale form, the output will only produce rows and columns. The command will output (680, 850, 2) where 680 is the width, and 850 is the height in pixel size, while 2 is the image channel (RGB), or it means that the image has 680 rows and 850 columns. Shape ) to display the dimensions of our source image. Henceforth, we will use the image above in this paper. Let’s first try reading our image source and displaying it with the functions previously described. ![]() As explained earlier in this article, we will learn how to apply resizing, cropping, and rotating techniques to images. Now we can go back to the original topic of basic image manipulation in OpenCV and Python. ![]() import cv2įor details on OpenCV Core Image Operations, please read the OpenCV documentation. To write / save images in OpenCV using a function cv2.imwrite()where the first parameter is the name of the new file that we will save and the second parameter is the source of the image itself. import cv2Ĭv2.imshow('Displaying Images', img) Writing / Saving Images Displaying an Imageĭisplaying an image in OpenCV using a function cv2.imshow()where the first parameter is the window name to display the image and the second parameter is the image itself. destroyAllWindows ( ) is to close other windows that are currently open. Whiskey ( 0 ) is to keep the window displaying the image. The corresponding code with the Python SDK will be image_url = imagekit.To read images in OpenCV, use a function cv2.imread()where the first parameter is the image file name complete with its extension. Similarly, if we want to get a 400 x 300px resized image from ImageKit, the URL will contain height and width transformation parameters. Print(f"Original size : ) Example of generating a URL at width 200px with the Python SDK ![]() Pillow provides the resize() method, which takes a (width, height) tuple as an argument. Install the latest version of Pillow with pip. Pillow is one of the most popular options for performing basic image manipulation tasks such as cropping, resizing, or adding watermarks. We will be using an image by Asad from Pexels for all examples in this article. The free plan has access to all the features we need for image resizing and other transformations. When we get to ImageKit later in this article, you will need to sign up for a free account on ImageKit's website. Make sure you have a recent version of Python installed on your system, preferably Python 3.6+, then spin up a virtual environment. Simplify all of it by using ImageKit, a complete image optimization product.This article will walk you through those options and look at ImageKit - a cloud-based, ready-to-use solution that offers real-time image manipulation. Python offers a rich set of options to perform some of the routine image resizing tasks. Resizing images is an integral part of the web, whether to display images on your website or app, store lower-resolution images, or generate a training set for neural networks. ![]()
