保存图像:在调用resize()函数后,我们可以使用Image.save()函数将调整后的图像保存下来,然后再使用Image.show()函数来显示保存的图像,代码如下所示: fromPILimportImage# 打开图像image=Image.open("image.jpg")# 调整图像尺寸width,height=image.size resized_image=image.resize((width//2,height//2))# 保存图...
image=resize_image(image, IMAGE_SIZE, IMAGE_SIZE) cv2.imwrite(full_path, image) print(dir_item)if__name__ =='__main__': read_path('/home/xx/xx/xx') list去重 1. a=[1,2,3,1,5,1,6] print(list(set(a))) 2. a=[[1,2],[5,6],[1,2]] ...

Python中可以使用PIL库(Pillow)来实现图像的旋转和缩放功能。下面是一个示例代码: from PIL import Image # 打开图像文件 image = Image.open('example.jpg') # 旋转图像 rotated_image = image.rotate(45) # 旋转45度 # 缩放图像 resized_image = image.resize((200, 200)) # 缩放到200x200的大小 # ...
