Python Pillow: Your Image Journey Begins

Python tip:
To get started with image processing, use the Pillow library to open and display images.

from PIL import Image

# Make sure you have an image file (e.g., 'example.jpg') in the same directory
try:
    img = Image.open('example.jpg')
    print(f"Image format: {img.format}, size: {img.size}, mode: {img.mode}")
    img.show() # This will open the image in your default image viewer
except FileNotFoundError:
    print("Error: 'example.jpg' not found. Please create or provide an image file.")
except Exception as e:
    print(f"An error occurred: {e}")

Python tip:
Easily resize images to new dimensions using Pillow's resize() method.

from PIL import Image

try:
    img = Image.open('example.jpg')
    new_width = 300
    new_height = 200
    resized_img = img.resize((new_width, new_height))
    resized_img.save('example_resized.jpg')
    print(f"Image resized to {resized_img.size} and saved as 'example_resized.jpg'.")
except FileNotFoundError:
    print("Error: 'example.jpg' not found. Cannot resize.")
except Exception as e:
    print(f"An error occurred during resizing: {e}")

Python tip:
Convert images to different color modes, like grayscale, with convert().

from PIL import Image

try:
    img = Image.open('example.jpg')
    grayscale_img = img.convert('L') # 'L' mode for grayscale
    grayscale_img.save('example_grayscale.jpg')
    print("Image converted to grayscale and saved as 'example_grayscale.jpg'.")
except FileNotFoundError:
    print("Error: 'example.jpg' not found. Cannot convert.")
except Exception as e:
    print(f"An error occurred during conversion: {e}")

Python tip:
Crop a specific region from an image using the crop() method, specifying a bounding box (left, upper, right, lower).

from PIL import Image

try:
    img = Image.open('example.jpg')
    # Define the bounding box: (left, upper, right, lower)
    # This example crops the top-left 100x100 pixels
    cropped_img = img.crop((0, 0, 100, 100))
    cropped_img.save('example_cropped.jpg')
    print(f"Image cropped to {cropped_img.size} and saved as 'example_cropped.jpg'.")
except FileNotFoundError:
    print("Error: 'example.jpg' not found. Cannot crop.")
except Exception as e:
    print(f"An error occurred during cropping: {e}")

Python tip:
Rotate an image by a specified angle using rotate().

from PIL import Image

try:
    img = Image.open('example.jpg')
    rotated_img = img.rotate(90, expand=True) # Rotate 90 degrees clockwise, expand to fit
    rotated_img.save('example_rotated.jpg')
    print("Image rotated 90 degrees and saved as 'example_rotated.jpg'.")
except FileNotFoundError:
    print("Error: 'example.jpg' not found. Cannot rotate.")
except Exception as e:
    print(f"An error occurred during rotation: {e}")

Python tip:
Apply basic image filters from PIL.ImageFilter for quick visual effects.

from PIL import Image, ImageFilter

try:
    img = Image.open('example.jpg')
    blurred_img = img.filter(ImageFilter.BLUR)
    blurred_img.save('example_blurred.jpg')
    print("Image blurred and saved as 'example_blurred.jpg'.")

    sharpened_img = img.filter(ImageFilter.SHARPEN)
    sharpened_img.save('example_sharpened.jpg')
    print("Image sharpened and saved as 'example_sharpened.jpg'.")
except FileNotFoundError:
    print("Error: 'example.jpg' not found. Cannot apply filter.")
except Exception as e:
    print(f"An error occurred during filtering: {e}")
