    content="DRAFT"
    :font-size="24"
    :font-color="'rgba(255, 0, 0, 0.2)'"
    :rotate="-30"
    :width="200"
    :height="150"
  >
    <n-card title="Document Preview">
      <n-p>Document content goes here...</n-p>
    </n-card>
  </n-watermark>
</template>
```

### Confidential Document

<template>
  <n-watermark
    :content="'CONFIDENTIAL\nInternal Use Only'"
    cross
    :font-size="14"
    :font-color="'rgba(200, 50, 50, 0.15)'"
    :rotate="-20"
    :line-height="20"

  >
    <n-card>
      <n-p>Sensitive document content...</n-p>
    </n-card>
  </n-watermark>
</template>
```

### Company Branding

<template>
  <n-watermark
    content="© Company Name 2024"
    :font-size="12"
    :font-color="'rgba(0, 0, 0, 0.1)'"
    :rotate="-15"
    :x-gap="100"
    :y-gap="100"
  >
    <div class="content-area">
      <!-- Your content -->
    </div>
  </n-watermark>
</template>
```

### Toggle Watermark

```vue
<template>
  <div>
    <n-space class="mb-4">
      <n-switch v-model:value="showWatermark" />
      <n-text>Show Watermark</n-text>
    </n-space>
    <n-watermark
      v-if="showWatermark"
      content="Preview"
      :font-size="20"
      :rotate="-25"
    >
      <n-card>
        <n-p>Content with conditional watermark...</n-p>
      </n-card>
    </n-watermark>
    <n-card v-else>
      <n-p>Content without watermark...</n-p>
    </n-card>
  </div>
</template>

<script setup>
import { ref } from 'vue'

const showWatermark = ref(true)
</script>
```

### Custom Styled Watermark

```vue
<template>
  <n-watermark
    content="Custom Style"
    :font-size="18"
    :font-color="'rgba(100, 100, 255, 0.2)'"
    :font-style="'italic'"
    :font-weight="600"
    :rotate="-15"
    :global-rotate="5"
    :x-gap="50"
    :y-gap="50"
  >
    <n-card>
      <n-p>Content with custom styled watermark...</n-p>
    </n-card>
  </n-watermark>
</template>
```

## Best Practices

1. **Use appropriate opacity**: Keep watermarks subtle to not distract from content
   ```vue
   <n-watermark :font-color="'rgba(128, 128, 128, 0.15)'" />
   ```

2. **Set rotation for visual appeal**: Use slight rotation for better coverage
   ```vue
   <n-watermark :rotate="-15" />
   ```

3. **Use cross for better coverage**: Enable cross for denser watermark pattern
   ```vue
   <n-watermark cross />
   ```

4. **Control content selection**: Set selectable based on use case
   ```vue
   <n-watermark :selectable="false" />
   ```

5. **Use fullscreen for page-level protection**: Apply fullscreen for entire page
   ```vue
   <n-watermark fullscreen content="Confidential" />
   ```

6. **Check image cross-origin**: Ensure image URLs allow cross-origin access
   - Image watermarks may fail due to CORS restrictions

7. **Adjust gap and offset**: Fine-tune spacing for optimal coverage
   ```vue
   <n-watermark :x-gap="50" :y-gap="50" :x-offset="25" :y-offset="25" />
   ```

8. **Use multiline for more information**: Combine multiple lines with `\n`
   ```vue
   <n-watermark :content="'Company\nConfidential'" text-align="center" />
   ```
