问题描述
使用PIL读取图像后对其进行Resize时由于PIL 版本问题出现AttributeError: module 'PIL.Image' has no attribute 'ANTIALIAS'
具体的代码如下
image = image.resize((scaled_width, scaled_height), Image.ANTIALIAS)
原因分析
在新版本pillow（10.0.0之后）Image.ANTIALIAS 被移除了，取而代之的是Image.LANCZOS or Image.Resampling.LANCZOS，相关描述可以可以在pillow的releasenotes中查到。
更多被移除的方法如下

| Image.LINEAR | Image.BILINEAR or Image.Resampling.BILINEAR |
| Image.CUBIC | Image.BICUBIC or Image.Resampling.BICUBIC |

回到刚刚的问题
解决方案
对于刚刚的问题 解决方案就是将Image.ANTIALIAS 替换为 Image.LANCZOS 或 Image.Resampling.LANCZOS
修改后的代码如下：
image = image.resize((scaled_width, scaled_height), Image.LANCZOS)
以上仅记录以下自己在Debug过程中遇到的问题，方便后续修改类似的程序。
