Python - 100x100 image with random pixel colour

To generate a 100x100 image with random pixel colors using Python, you can utilize the PIL (Python Imaging Library) module, which is now known as Pillow. Here's a step-by-step guide to create such an image:

Step-by-Step Solution

  1. Install Pillow: If you haven't installed Pillow yet, you can install it using pip:

    pip install Pillow

  2. Create the Image: Use Python to create a 100x100 image with random pixel colors.

  3. Save the Image: Optionally, save the generated image to a file.

Here's a Python script to accomplish this:

from PIL import Image import random # Dimensions of the image width = 100 height = 100 # Create a new image with RGB mode image = Image.new("RGB", (width, height)) # Access the pixel data pixels = image.load() # Iterate over each pixel and set a random color for x in range(width): for y in range(height): # Generate a random RGB color tuple red = random.randint(0, 255) green = random.randint(0, 255) blue = random.randint(0, 255) color = (red, green, blue) # Set the pixel color pixels[x, y] = color # Show the image (optional) image.show() # Save the image to a file (optional) image.save("random_image.png")

Explanation:

  • Image Creation: Image.new("RGB", (width, height)) creates a new 100x100 RGB image.

  • Pixel Access: pixels = image.load() allows direct manipulation of the pixel data.

  • Random Color Generation:

    • random.randint(0, 255) generates random values for red, green, and blue channels.
    • color = (red, green, blue) creates a random RGB color tuple.

  • Setting Pixels: pixels[x, y] = color sets each pixel in the image with the randomly generated color.

  • Displaying and Saving:

    • image.show() displays the generated image using the default image viewer.
    • image.save("random_image.png") saves the generated image to a PNG file named "random_image.png". You can change the file format by adjusting the file extension (e.g., "random_image.jpg", "random_image.bmp").

Notes:

  • File Formats: Pillow supports various image file formats, including PNG, JPEG, BMP, GIF, etc. Adjust the file format in image.save() as needed.

  • Performance: Generating random colors for each pixel can be computationally expensive. For large images or performance-critical applications, consider optimizing or parallelizing the pixel generation process.

By running this script, you will generate a 100x100 image (random_image.png in this example) filled with random pixel colors. Adjust the script according to your specific requirements or integrate it into your larger Python application as needed.
