Let us understand with the help of an example,Python code to crop center portion of a NumPy image# Import numpy import numpy as np # Creating a numpy image arr = np.array([[88, 93, 42, 25, 36, 14, 59, 46, 77, 13, 52, 58], [43, 47, 40, 48, 23, 74, 12, 33, 58, ...
if image_response.status_code == 200: with open(f"{save_directory}/image_{index}.jpg", "wb") as f: f.write(image_response.content)``` 说明: 此Python脚本旨在从网站批量下载图像。它为网站提供返回图像URL数组的JSONAPI。然后,该脚本循环访问URL并下载图像,并将其保存到指定目录。
