Print('Size after resizing using 2nd way -> ',resized_img_2nd_way. Print('Size of original image -> ',img.shape) Print('Size after resizing using 2nd way -> ',resized_img_2nd_way.shape) Final resized results Syntax: cv2. Print('Size after resizing using 1st way -> ',resized_img_1st_way.shape) ImageMagick provides so many algorithms for resizing. Aspect Ratio can be preserved by calculating width or height for given target height or width respectively. The aspect ratio can be preserved or not, based on the requirement. Resizing, by default, does only change the width and height of the image. img Image.open('././doc/static/stinkbug.png') img.thumbnail( (64, 64)) resizes image in-place imgplot plt.imshow(img) Here we use the default interpolation ('nearest'), since we did not give imshow () any interpolation argument. print('Size of original image -> ',img.shape) It scales an image into a desired size even if the desired size is larger than the original size. To resize an image in Python, you can use cv2.resize () function of OpenCV library cv2. How To Resize A Single Image With Python We set a base width which we would like the image to be. We'll use the Pillow library that we used to load the image also to resize the image. Step 5 – Finally let’s check the size of our images. It does this by determining what percentage 300 pixels is of the original width (img.size0) and then multiplying the original height (img.size1) by that percentage. How to Rotate An Image Using Python We specify our source and destination image files We specify a rotation angle in this case we will be rotating the image. Resized_img_2nd_way = cv2.resize(img,None,fx=0.3,fy=0.4,interpolation=cv2.INTER_AREA) This script will resize an image (somepic.jpg) using PIL (Python Imaging Library) to a width of 300 pixels and a height proportional to the new width. The second way is that we can pass dsize as None and pass fx and fy as (scale factor for width) and (scale factor for height) for scaling the image in the horizontal axis and vertical axis respectively.The first way is directly passing the dsize argument as (required width, required height) and not passing fx,fy.INTER_CUBIC – a bicubic interpolation over 4×4 pixel neighborhood INTER_LANCZOS4 – a Lanczos interpolation over 8×8 pixel neighborhood But when the image is zoomed, it is similar to the INTER_NEAREST method. It may be a preferred method for image decimation, as it gives moire’-free results. INTER_NEAREST – a nearest-neighbor interpolation INTER_LINEAR – a bilinear interpolation (used by default) INTER_AREA – resampling using pixel area relation. Image-Resizer-Tool Open Source app with gui interface to adjust all images in the folder jpg or png width and height X/Y installation: Install Python 3.6.8 (MAKE SURE YOU CLICK ADD TO PATH OPTION IN INSTALLER) Usage: -open run. flag that takes one of the following methods.
