Pil resize image3/27/2023 ![]() We need to calculate the padding length in 4 side of the resized image before applying this method. Instead of the 4-tuple, you could instead use a 2-tuple to add the same number of pixels on the left/right and top/bottom, or a 1-tuple to add the same number of pixels to all sides. The PIL ImageOps module has a expand() function that will add borders to the 4 side of an image. # and bottom, making sure to account for even or odd numbersĪdd_left = add_right = (new_size - old_size) // 2Īdd_left = (new_size - old_size) // 2Īdd_right = ((new_size - old_size) // 2) + 1Īdd_top = add_bottom = (new_size - old_size) // 2Īdd_top = (new_size - old_size) // 2Īdd_bottom = ((new_size - old_size) // 2) + 1 # Set number of pixels to expand to the left, top, right, cv2 resize can upscale, downscale, resize to a desired size while considering aspect ratio. imagetf4D tf.expanddims(imagetf,0) doing bilinear resize imagetfresized4D tf.image.resizebilinear(imagetf4D, (300,300)) squeezing back the image to 3D imagetfresized tf.squeeze(imagetfresized4D) Above is. To resize image in Python, OpenCV cv2.resize() can be used. ![]() Refresh the page, check Medium ’s site status, or find something interesting to read.

Batch-Resizing Images in Python with Pillow by Joe T. Use userImage userImage.resize (size), because resize () returns a copy of the image, resized it doesn't actively resize the image. This code accounts for odd pixel sizes: from PIL import Image Negative numbers for left and top will add black pixels to those edges, while numbers greater than the original width and height for right and bottom will add black pixels to those edges. PIL's crop method can actually handle this for you by using numbers that are outside the bounding box of the original image, though it's not explicitly stated in the documentation. ![]()
