## 何时使用 {#when-to-use}
- 页面需要添加水印标识版权时使用。
- 适用于防止信息盗用。
## 代码演示 {#examples}
### 基本
最简单的用法。
```tsx
import React from 'react';
import { Watermark } from 'antd';
const App: React.FC = () => (
);
export default App;
```
### 多行水印
通过 `content` 设置 字符串数组 指定多行文字水印内容。
```tsx
import React from 'react';
import { Watermark } from 'antd';
const App: React.FC = () => (
);
export default App;
```
### 图片水印
通过 `image` 指定图片地址。为保证图片高清且不被拉伸，请设置 width 和 height, 并上传至少两倍的宽高的 logo 图片地址。
```tsx
import React from 'react';
import { Watermark } from 'antd';
const App: React.FC = () => (
);
export default App;
```
### 自定义配置
通过自定义参数配置预览水印效果。
```tsx
import React, { useState } from 'react';
import { ColorPicker, Flex, Form, Input, InputNumber, Slider, Typography, Watermark } from 'antd';
import type { ColorPickerProps, GetProp, WatermarkProps } from 'antd';
type Color = Extract, string | { cleared: any }>;
const { Paragraph } = Typography;
interface WatermarkConfig {
content: string;
color: string | Color;
fontSize: number;
zIndex: number;
rotate: number;
gap: [number, number];
offset?: [number, number];
}
const App: React.FC = () => {
const [form] = Form.useForm();
const [config, setConfig] = useState({
content: 'Ant Design',
color: 'rgba(0, 0, 0, 0.15)',
fontSize: 16,
zIndex: 11,
rotate: -22,
gap: [100, 100],
offset: undefined,
});
const { content, color, fontSize, zIndex, rotate, gap, offset } = config;
const watermarkProps: WatermarkProps = {
content,
zIndex,
rotate,
gap,
offset,
font: { color: typeof color === 'string' ? color : color.toRgbString(), fontSize },
};

The light-speed iteration of the digital world makes products more complex. However,
human consciousness and attention resources are limited. Facing this design
contradiction, the pursuit of natural interaction will be the consistent direction of
Ant Design.
Natural user cognition: According to cognitive psychology, about 80% of external
information is obtained through visual channels. The most important visual elements in
the interface design, including layout, colors, illustrations, icons, etc., should fully
absorb the laws of nature, thereby reducing the user's cognitive cost and bringing
authentic and smooth feelings. In some scenarios, opportunely adding other sensory
channels such as hearing, touch can create a richer and more natural product experience.
Natural user behavior: In the interaction with the system, the designer should fully
understand the relationship between users, system roles, and task objectives, and also
contextually organize system functions and services. At the same time, a series of
methods such as behavior analysis, artificial intelligence and sensors could be applied
to assist users to make effective decisions and reduce extra operations of users, to
save users' mental and physical resources and make human-computer interaction more
natural.

export default App;
```
### Modal 与 Drawer
在 Modal 与 Drawer 中使用。
```tsx
import React from 'react';
import { Button, Drawer, Flex, Modal, Watermark } from 'antd';
const style: React.CSSProperties = {
height: 300,
display: 'flex',
justifyContent: 'center',
alignItems: 'center',
backgroundColor: 'rgba(150, 150, 150, 0.2)',
};
