Course Introduction：Use Pillow to adjust the image size to select methods based on whether the aspect ratio is maintained: 1. Direct resize() will stretch the image, which is suitable for scenes where proportions are not required; 2. Use thumbnail() to automatically maintain the aspect ratio, generate undistorted thumbnails, and the maximum size does not exceed the specified value; 3. Custom resize_with_aspect_ratio() function can flexibly control the target width and height, and improve quality by calculating the scaling ratio and using LANCZOS resampling; 4. Pay attention to the image mode during processing, and convert it to RGB if necessary to avoid saving errors; 5. It is recommended to use thumbnail() or custom functions to maintain the image proportions, avoid deformation, and finally save or display the results.
