Creating a grayscale image in a python byte array
Download this code from
Grayscale images are images without any color information, represented using shades of gray. In this tutorial, we will walk through the process of creating a grayscale image in Python and storing it in a byte array. We will be using the Python Imaging Library (PIL), also known as the Pillow library, to work with images.
Before you begin, make sure you have Python installed on your system. You can install Pillow, the Python Imaging Library fork, using pip if you haven't already:
In this example, we first create a new grayscale image with a specified width and height using the Image.new method from the Pillow library. We use the 'L' mode, which represents 8-bit pixels in black and white.
We then access the image data as a list of pixels using the load() method. Inside the nested loops, you can set the pixel values based on your desired grayscale logic. In this case, we set all pixels to a constant value of 128, resulting in a medium gray tone.
The image can be saved to a file using the save() method if you want to visualize the output. Finally, the grayscale image is converted to a byte array using the tobytes() method and stored in the image_byte_array variable.
Feel free to modify the pixel values or grayscale logic according to your requirements to create different grayscale effects.
