# 图文混排

图文混排是指图片与文字混合排列，文字可展示于图片四周。此排列方式能够直观呈现页面信息，增强视觉冲击力，使页面展示效果更加多样化。

## 使用Span和ImageSpan实现图文混排

通过设置[Text](https://developer.huawei.com/consumer/cn/doc/harmonyos-references/ts-basic-components-text)组件[textVerticalAlign](https://developer.huawei.com/consumer/cn/doc/harmonyos-references/ts-basic-components-text#textverticalalign20)属性和设置[ImageSpan](https://developer.huawei.com/consumer/cn/doc/harmonyos-references/ts-basic-components-imagespan)组件[verticalAlign](https://developer.huawei.com/consumer/cn/doc/harmonyos-references/ts-basic-components-imagespan#verticalalign)为ImageSpanAlignment.FOLLOW_PARAGRAPH，实现商品价格优惠信息展示的应用场景。

```TypeScript
Text() {
  // 请将$r('app.media.hot_sale')替换为实际资源文件
  ImageSpan($r('app.media.hot_sale'))
    .width(50)
    .height(30)
    .borderRadius(5)
    .verticalAlign(ImageSpanAlignment.FOLLOW_PARAGRAPH)
  // 请将$r('app.string.surprise_price')替换为实际资源文件，在本示例中该资源文件的value值为"惊喜价 ￥1299"
  Span($r('app.string.surprise_price'))
    .fontSize(25)
    .fontColor(Color.Red)
  Span('1599')
    .decoration({
      type: TextDecorationType.LineThrough,
      color: Color.Grey,
      style: TextDecorationStyle.SOLID
    })
    .fontSize(16)
}.textVerticalAlign(TextVerticalAlign.CENTER)
```

## 使用属性字符串实现图文混排

通过[ImageAttachment](https://developer.huawei.com/consumer/cn/doc/harmonyos-references/ts-universal-styled-string#imageattachment)添加图片，[TextStyle](https://developer.huawei.com/consumer/cn/doc/harmonyos-references/ts-universal-styled-string#textstyle)设置多种文本样式，实现商品详情信息展示的应用场景。

```TypeScript
// resourceGetString封装工具，从资源中获取字符串

  async aboutToAppear() {
    hilog.info(DOMAIN, TAG, BUNDLE + 'aboutToAppear initial imagePixelMap');
    // $r('app.media.sky')需要替换为开发者所需的资源文件。
    this.imagePixelMap = await this.getPixmapFromMedia($r('app.media.sky'));
  }

  private async getPixmapFromMedia(resource: Resource) {
    try {
      let unit8Array = await this.getUIContext().getHostContext()?.resourceManager?.getMediaContent(resource.id);
      let imageSource = image.createImageSource(unit8Array?.buffer?.slice(0, unit8Array?.buffer?.byteLength));

    }
    return undefined;
