## Watermark 组件示例
### 基本
最简单的用法。

```tsx
import React from 'react';
import { Watermark } from 'antd';
const App: React.FC = () => (
  <Watermark content="Ant Design">
    <div style={{ height: 500 }} />
  </Watermark>
);
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 = () => (
  <Watermark content={['Ant Design', 'Happy Working']}>
    <div style={{ height: 500 }} />
  </Watermark>
);
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 = () => (
  <Watermark
    height={30}
    width={130}
    image="https://mdn.alipayobjects.com/huamei_7uahnr/afts/img/A*lkAoRbywo0oAAAAAAAAAAAAADrJ8AQ/original"
  >
    <div style={{ height: 500 }} />
  </Watermark>
);
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<GetProp<ColorPickerProps, 'value'>, 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<WatermarkConfig>({
    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 },
  };
  return (
    <Flex gap="medium">
      <Watermark {...watermarkProps}>
        <Typography>
          <Paragraph>
            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.
          </Paragraph>
          <Paragraph>
            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&apos;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.
          </Paragraph>
          <Paragraph>
            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&apos; mental and physical resources and make human-computer interaction more
            natural.

        />
      </Watermark>
      <Form
        style={{
          width: 280,
          flexShrink: 0,
          borderInlineStart: '1px solid #eee',
          paddingInlineStart: 16,

        form={form}
        layout="vertical"
        initialValues={config}
        onValuesChange={(_, values) => {
          setConfig(values);
        }}
      >

        </Form.Item>
        <Form.Item name="fontSize" label="FontSize">

          </Flex>
        </Form.Item>
      </Form>
    </Flex>
  );
};
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)',
};
const placeholder = <div style={style}>A mock height</div>;
const App: React.FC = () => {
  const [showModal, setShowModal] = React.useState(false);
  const [showDrawer, setShowDrawer] = React.useState(false);
  const [showDrawer2, setShowDrawer2] = React.useState(false);
  const closeModal = () => setShowModal(false);
  const closeDrawer = () => setShowDrawer(false);
  const closeDrawer2 = () => setShowDrawer2(false);
  return (
    <>
      <Flex gap="medium">
        <Button type="primary" onClick={() => setShowModal(true)}>
          Show in Modal
        </Button>
        <Button type="primary" onClick={() => setShowDrawer(true)}>
          Show in Drawer
        </Button>
        <Button type="primary" onClick={() => setShowDrawer2(true)}>
          Not Show in Drawer
        </Button>
      </Flex>
      <Watermark content="Ant Design">
        <Modal
          destroyOnHidden
          open={showModal}
          title="Modal"
          onCancel={closeModal}
          onOk={closeModal}
        >
          {placeholder}
        </Modal>
        <Drawer destroyOnHidden open={showDrawer} title="Drawer" onClose={closeDrawer}>
          {placeholder}
        </Drawer>
      </Watermark>
      <Watermark content="Ant Design" inherit={false}>
        <Drawer destroyOnHidden open={showDrawer2} title="Drawer" onClose={closeDrawer2}>
          {placeholder}
        </Drawer>
      </Watermark>
    </>
  );
};
export default App;
```
