![]() ![]() One important hint, though: Replace im.thumbnail(size)īy default, PIL uses the Image.NEAREST filter for resizing which results in good performance, but poor quality. I also recommend using PIL's thumbnail method, because it removes all the ratio hassles from you. trimmer img.resetcoords() resize to 180px tall at original aspect ratio originalsize img.size scale. Img = img.resize((basewidth,hsize), Image.ANTIALIAS) Hsize = int((float(img.size)*float(wpercent))) How to Resize an Image using Python While. Change "basewidth" to any other number to change the default width of your images. Dimensions: It is 2048×1152 this is also good to know to see if the resize will work after we execute some code later.

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.

There is of course also a library method to do this: the method Image.thumbnail.īelow is an (edited) example from the PIL documentation. You’ll also learn how to specify a percentage to scale by, a maximum width, and a maximum height. Then, compute a resize ratio by taking min(maxwidth/width, maxheight/height). ![]()
