### 处理异常图片水印
|
|
|
|
|
|
|
|
|
|
当使用图片水印且图片加载异常时，可以同时添加 `content` 防止水印失效（自 5.2.3 开始支持）。
|
|
|
|
|
|
|
|
|
|
```typescript jsx
|
|
|
|
|
<Watermark
|
|
|
|
|
height={30}
|
|
|
|
|
width={130}
|
|
|
|
|
content="Ant Design"
|

|
|
|

|
|
|
|
|
<div style={{ height: 500 }} />
|
|
|
|
|
</Watermark>
|
|
|
|
|
```
|
