May 24, 2009 · Using PIL, save a NumPy array arr by doing: from PIL import Image im = Image.fromarray(arr) im.save("your_file.jpeg") See the docs for available data formats, including JPEG, PNG, and so on.

Feb 20, 2024 · This article guides you through five different methods to convert a NumPy array that represents image data into a JPEG file. For example, we’ll start with an input of a NumPy array with pixel values and aim to create a JPEG image as the desired output.

scipy.misc.imshow() is deprecated. Use matplotlib.pyplot.imshow(data) instead. Also, in IPython, you need to run matplotlib.pyplot.show() to show the image display window.

Apr 1, 2025 · The Image.fromarray () function is used for this task, which takes a NumPy array as input and creates a PIL Image object. This allows the array to be manipulated as a standard image, making it suitable for tasks like displaying, saving or further processing the image.

Feb 2, 2024 · In this article, we will explore different methods to save a NumPy array as an image in Python. The Image.fromarray() function is part of the Pillow library (PIL) in Python, and it is designed to create a Pillow Image object from a NumPy array.

Jan 23, 2024 · Converting these arrays back into images can be essential for visualizing results, storing them for later use, or for processing with image-specific software. In this tutorial, we will explore how to save a NumPy array as an image file using multiple code examples.

Feb 20, 2024 · The Image.fromarray() function converts a NumPy array to a PIL image object, which can then be saved to a file. This method supports various image modes (like L for grayscale and RGB for color images).

To save the Numpy array as a local image, use the save () function and pass the image filename with the directory where to save it. This will save the Numpy array as a jpeg image. Following …

To convert a given NumPy array to an image using Pillow library in Python, call Image.fromarray () function and pass the given NumPy array as argument. The function returns a PIL Image object.

In this article, we have explained the process to convert Numpy array to an Image in format like jpeg or png. We have presented the code Python code as well.
