Oct 13, 2015 · I think you can simply call the PIL image's .tobytes() method, and from there, to convert it to an array, use the bytes built-in. #assuming image is a flattened, 3-channel numpy array of e.g. 600 x 600 pixels bytesarray = bytes(Image.fromarray(array.reshape((600,600,3))).tobytes())

Aug 2, 2019 · Image.tobytes() Return image as a bytes object. Syntax: Image.tobytes(encoder_name=’raw’, *args) Parameters: encoder_name – What encoder to use. The default is to use the standard “raw” encoder. args – Extra arguments to the encoder. Returns: A bytes object. Image Used:

Apr 23, 2025 · Write a Python program to read an image file into a bytes object, modify some of its bytes, and then save the result as a new image file. Write a Python script to open an image file in binary mode, convert its bytes to a base64 string, and then decode it back to image bytes.

Converting an image into a byte array in Python is a common task when working with image processing or data transmission. In this topic, we explored different approaches to achieve this. The first example demonstrates the use of the base64 module to encode the image file into a …

Nov 23, 2024 · Learn the best methods to convert PIL images to byte arrays using Python, along with practical examples and alternative approaches.

Python script to convert image to byte array, of color depth = 4, and bit depth = 2

Mar 15, 2014 · # Convert image to bytes import PIL.Image as Image pil_im = Image.fromarray(image) b = io.BytesIO() pil_im.save(b, 'jpeg') im_bytes = b.getvalue()

Jan 8, 2025 · Converting the PIL image into bytes is an easy and efficient way to modify, store or move image information within Python. Utilizing the Pillow library, and Python’s built-in io module it is possible to handle the process with ease.

Feb 8, 2021 · CV2 vs. Bytes. To convert image bytes to CV2 image is more complicated than to PIL. First, we need to convert bytes to NumPy array with method frombuffer. Then, the function imdecode reads the image from the specified buffer array in the memory.

To convert a PIL image to a byte array in Python 3, we can make use of the `tobytes()` method provided by the PIL library. This method returns a byte string containing the pixel data of the image. Here is an example:
