使用python对图片resize

from PIL import Image

def resize_image(input_path, output_path, target_size):
    # 打开图像
    with Image.open(input_path) as img:
        # 获取原始宽度和高度
        original_width, original_height = img.size
        
        # 计算缩放比例
        aspect_ratio = int(original_width / original_height)/8*8
        
        # 根据目标宽度或高度计算新的尺寸
        if original_width > original_height:
            new_width = target_size
            new_height = int(target_size / aspect_ratio)
        else:
            new_height = target_size
            new_width = int(target_size * aspect_ratio)
        
        # 调整图像大小
        resized_img = img.resize((new_width, new_height), Image.LANCZOS)
        
        # 保存调整后的图像
        resized_img.save(output_path)

# 示例用法
resize_image('D:/Profile/Desktop/gpt/1101_lte.png', 'D:/Profile/Desktop/gpt/resize_1101_lte.png', 16)  # 将图像调整为宽度或高度为800
