## 弃用*路径操作*

`deprecated` 参数可以把*路径操作*标记为<abbr title="过时，建议不要使用">弃用</abbr>，无需直接删除：

```Python hl_lines="16"
{!../../docs_src/path_operation_configuration/tutorial006.py!}
```

API 文档会把该路径操作标记为弃用：

<img src="/img/tutorial/path-operation-configuration/image04.png">

下图显示了正常*路径操作*与弃用*路径操作* 的区别：

        ClassLoader classLoader = Thread.currentThread().getContextClassLoader();
        File outputFile = File.createTempFile("generator_", ".png");

        String imagePath = "thumbnail/600x400.png";
        try (ImageInputStream input = ImageIO.createImageInputStream(classLoader.getResourceAsStream(imagePath))) {
            generator.saveImage(input, outputFile);
        }
