The file object must implement file.read, Parametersįp – A filename (string), pathlib.Path object or a file object. The file until you try to process the data (or call the The file remains open and the actual image data is not read from This is a lazy operation this function identifies the file, but
Opens and identifies the given image file. open ( fp, mode = 'r', formats = None ) ¶ save ( file + ".thumbnail", "JPEG" ) Functions ¶ PIL.Image. PIL Package (autodoc of remaining modules)įrom PIL import Image import glob, os size = 128, 128 for infile in glob.ImageChops (“Channel Operations”) Module.Open, rotate, and display an image (using the default viewer).The above is how to use python package pillow to convert the image background into transparent. Of course, if the background is all white, there is no obvious difference, hahaha. The background of this one is already transparent. JPG format does not seem to support transparent backgrounds. image.save('output.png')įinally, remember to save the picture in PNG format. Of course, you can set what color you want to convert here. Then we first take out the pixel value of this picture and determine whether the pixel is white (255, 255, 255): # TransparencyĪs you can see, I replaced all dots with pixel values (255, 255, 255) with transparent. This is why we need to convert to this format. RGBA stands for Red, Green, Blue and Alpha channel.Īlpha channel stands for transparency. To make the image background transparent, we need to change " RGB" to " RGBA" first. We can see that this is a file of data type, and the mode of this file is "RGB". If it is the first time to use Pillow, use the following command to install it: pip3 install pillowĪfter the installation is over, let's look at an example: # -*- coding: utf-8 -*. So in below, we use the Pillow package to perform conversion processing. If you want to know more how to use Pillow module, you can refer to here: Ĭonvert the background of the picture to transparentĪs we can see, most of the background color is white color ( rgb(255, 255, 255)). If we want to convert a picture background into transparent, we can use the Pillow package in Python to do it.
