HarmonyOS 鸿蒙Next关于使用createPixelMapSync中使用RGB_888生成图像不显示的问题

HarmonyOS 鸿蒙Next关于使用createPixelMapSync中使用RGB_888生成图像不显示的问题 我用createPixelMapSync中，如果使用参数RGBA_8888，能正常显示图片，但是如果使用RGB_888，就显示不了图片，如下面代码所示，调用testVoid正常，调用testVoid_2不正常。

完整代码如下：

import { image } from '@kit.ImageKit';
import ArrayList from '@ohos.util.ArrayList';

const TAG: string = "TestPage2"
@Entry
@Component
export struct TestPage2 {

  @State pixelMap: ArrayList<PixelMap> = new ArrayList()
  @State duration: number= 1000

  build() {
    Column(){
      Image(this.pixelMap[0]).width(200).height(200)
    }.width('100%')
  }

  aboutToAppear(){
    this.testVoid_2();
  }

  async testVoid(){
    let len = 100*100;
    let bytes = 4;
    let color = new Uint8Array(len*bytes)
    for(let i=0;i<len;i++){
      color[i*bytes] = 0x11;
      color[i*bytes+1] = 0x55;
      color[i*bytes+2] = 0xff;
      color[i*bytes+3] = 0xff;
    }

    let opts: image.InitializationOptions = { editable: true, pixelFormat: image.PixelMapFormat.RGBA_8888,
      size: { height: 100, width: 100 } , alphaType:image.AlphaType.OPAQUE}

    this.pixelMap = new ArrayList()
    this.pixelMap.add(image.createPixelMapSync(color.buffer, opts));
  }

  async testVoid_2(){
    let len = 100*100;
    let bytes = 3;
    let color = new Uint8Array(len*bytes)
    for(let i=0;i<len;i++){
      color[i*bytes] = 0x11;
      color[i*bytes+1] = 0x55;
      color[i*bytes+2] = 0xff;
    }

    let opts: image.InitializationOptions = { editable: true, pixelFormat: image.PixelMapFormat.RGB_888,
      size: { height: 100, width: 100 } , alphaType:image.AlphaType.OPAQUE}

    this.pixelMap = new ArrayList()
    this.pixelMap.add(image.createPixelMapSync(color.buffer, opts));
  }
}
