Python Imaging Library

PIL offers several standard procedures for image manipulation. These include: • per-pixel manipulations, • masking and transparency handling, • image filtering, such as blurring, contouring, smoothing, or edge finding, • image enhancing, such as sharpening, adjusting brightness, contrast or color, • adding text ==File formats==

Supported file formats include PPM, PNG, JPEG, GIF, TIFF, and BMP. PIL is extensible, allowing users to create custom decoders for any file format. == Programming examples ==

import os from PIL import Image def convert_jpegs_to_pngs(folder_path): # Checks if the provided path is a folder if not os.path.isdir(folder_path): print(f"Error: {folder_path} is not a valid folder.") return # Iterates over all files in the folder for filename in os.listdir(folder_path): # Checks if the file has a .jpg or .jpeg extension if filename.lower().endswith(".jpg") or filename.lower().endswith(".jpeg"): # Full path of the file jpeg_path = os.path.join(folder_path, filename) # Path for the converted file png_path = os.path.join(folder_path, os.path.splitext(filename)[0] + ".png") try: # Opens the JPEG image with Image.open(jpeg_path) as img: # Converts and saves as PNG img.save(png_path, "PNG") print(f"Converted {jpeg_path} to {png_path}") except Exception as e: print(f"Error converting {jpeg_path}: {e}") ==References==
