The corresponding code with the Python SDK will be image_url = imagekit. 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. Before we dive into compressing images, let's grab a function from this tutorial to print the file size in a friendly format: def getsizeformat(b, factor1024, suffix'B'): ''' Scale bytes to its. Open up a new Python file and import it: import os from PIL import Image. When we get to ImageKit later in this article, you will need to sign up for a free account on ImageKit's website. Alright, to get started, let's install Pillow: pip install Pillow. Make sure you have a recent version of Python installed on your system, preferably Python 3.6+, then spin up a virtual environment. Instead, it returns another Image with the new dimensions. The resize () function doesn’t modify the used image. Simplify all of it by using ImageKit, a complete image optimization product To resize an image, you have to call the resize () method on the image object and passing in the two-integer tuple argument representing the width and height of the resized image.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. Scaled_img = cv2.copyMakeBorder(scaled_img, pad_top, pad_bot, pad_left, pad_right, borderType=cv2.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. Scaled_img = cv2.resize(img, (new_w, new_h), interpolation=interp) If len(img.shape) is 3 and not isinstance(padColor, (list, tuple, np.ndarray)): # color image but only one color provided New_h = np.round(float(new_w) / aspect).astype(int) Resize Images in Python With Pillow Import the PIL image class: from PIL import Image Load the image from a file with the open() function: image Image.open. If (saspect > aspect) or ((saspect = 1) and (aspect = 1)): # new vertical image

Pad_top, pad_bot = np.floor(pad_vert).astype(int), np.ceil(pad_vert).astype(int)Įlif aspect sh or w > sw: # shrinking image New_h = np.round(new_w/aspect).astype(int) Resize image by some percentage of the original size, so it can maintain the same aspect ratio. If you only want to decrease the size of an image, you can use the thumbnail() method. It provides resize() method to resize image to any target size, both for increase and decrease the size. So, after resizing we'll end up with a 1000xN or Nx1000 image (where N sh or w > sw: # shrinking imageĪspect = w/h # if on Python 2, you might need to cast as a float: float(w)/h Use PIL (Python Imaging Library) to resize the image. To shrink an image, it will generally look best with CV_INTER_AREA interpolation, whereas to enlarge an image, it will generally look best with CV_INTER_CUBIC (slow) or CV_INTER_LINEAR (faster but still looks OK). Note that if aspect is greater than 1, then the image is oriented horizontally, while if it's less than 1, the image is oriented vertically (and is square if aspect = 1).ĭifferent interpolation methods will look better depending on whether you're stretching the image to a larger resolution, or scaling it down to a lower resolution. So the most robust way to do this is to find the aspect ratio and calculate what the smaller dimension would be when the bigger one is stretched to 1000. However, resize() requires that you put in either the destination size (in both dimensions) or the scaling (in both dimensions), so you can't just put one or the other in for 1000 and let it calculate the other for you.

You can use resize() in OpenCV to resize the image up/down to the size you need.
