HarmonyOS 请问.png图片怎么在image控件中更改颜色

colorFilter要求参数为矩阵。如：

.colorFilter([0,0,0,0,0,
0,0,0,0,0,
0,0,0,0,0,
0.2,0.2,0.2,0.2,0.2,])

@Entry
@Component
struct Index {
  @State message: string = 'Hello World';

  build() {
    Column() {
      Text(this.message)
        .id('测试图片')
        .fontSize(50)
        .fontWeight(FontWeight.Bold)
      Image($rawfile('icon.png')).id('image1')
        .width(45)
        .colorFilter(
          [0, 0, 0, 0, 0,
            0, 0, 0, 0, 0,
            0, 0, 0, 0, 0,
            0.2, 0.2, 0.2, 0.2, 0.2])
    }
    .height('100%')
    .width('100%')
    .backgroundColor('#0f0f0f')
  }
}
