HarmonyOS ArkTS是否支持.9图

Image组件当前已支持.9图，可以通过设置resizable达到图片拉伸的效果。文档链接：https://developer.huawei.com/consumer/cn/doc/harmonyos-references-V5/ts-basic-components-image-V5#resizableoptions11

示例参考如下：

@Entry
@Component
struct SetSlice {
  @State top: number = 0
  @State bottom: number = 0
  @State left: number = 0
  @State right: number = 0
  @State fit: ImageFit = ImageFit.Cover
  // bubble3 宽472px高200px
  @State w: number = px2vp(472)
  @State h: number = px2vp(200)

  build() {

    Column({ space: 10 }) {
      Stack() {
        Image($r('app.media.bubble3'))
          .width(this.w)
          .height(this.h)
          .borderRadius(4)
          .resizable({
            slice: {
              top: this.top,
              bottom: this.bottom,
              left: this.left,
              right: this.right
            }
          })
