Here are the two most common ways to convert a Pillow image to NumPy. If you Google it, you'll probably find one of them: numpy.array (im) — makes a copy from an image to a NumPy array. numpy.asarray (im) — the same as numpy.array (im, copy=False). Supposedly, it doesn't make a copy but uses the memory of the original object instead.

Output: Explanation: Firstly we imported the Image module of the PIL (or pillow) library. Then we imported the Numpy library under the alias np (common convention).After which we created an Image object of our desired image (W3.jpg), and stored the object in the variable image.So, the image variable is of type PIL.JpegImagePlugin.JpegImageFile.; To create Numpy array out of this object, we. The Image module provides a class with the same name which is used to represent a PIL image. The module also provides a number of factory functions, including functions to load images from files, and to create new images. Image.convert() Returns a converted copy of this image. For the “P” mode, this method translates pixels through the palette.

As of PIL 1.1.6, the “proper” way to convert between images and numpy arrays is simply. 1. >>> pix = numpy.array (pic) although the resulting array is in a different format than yours (3-d array or rows/columns/rgb in this case). Then, after you make your changes to the array, you should be able to do either. Now we can use fromarray to create a PIL image from the NumPy array, and save it as a PNG file: from PIL import Image img = Image.fromarray(array) img.save('testrgb.png') In the code below we will: Create a 200 by 100 pixel array.
