HarmonyOS Path 是否支持矩阵变换

已经有方案参考demo:

import matrix4 from '@ohos.matrix4'
import { RenderNode, DrawContext, FrameNode, NodeController } from "@ohos.arkui.node"
import drawing from "@ohos.graphics.drawing"

class MyFrameNode extends FrameNode {

  onDraw(context: DrawContext) {
    const canvas = context.canvas;
    const pen = new drawing.Pen();
    pen.setStrokeWidth(5);
    pen.setColor({alpha: 255, red: 255, green: 0, blue: 0});
    let path = new drawing.Path();
    path.arcTo(10, 10, 200, 200, 0, 270);
    canvas.attachPen(pen);
    canvas.drawPath(path);
    canvas.detachPen();
  }

}

class TextRenderNode extends RenderNode {
  async draw(context: DrawContext) {
    const canvas = context.canvas;
    const pen = new drawing.Pen();
    pen.setStrokeWidth(5);
    pen.setColor({alpha: 255, red: 255, green: 0, blue: 0});
    let path = new drawing.Path();
    path.arcTo(10, 10, 200, 200, 0, 270);
    canvas.attachPen(pen);
    canvas.drawPath(path);
    canvas.detachPen();
  }
}

class MyNodeController extends NodeController {
  private rootNode: FrameNode | null = null;
  private nodeArray: Array<RenderNode> = []
  addMyNode(item:RenderNode){
    this.nodeArray.push(item)
  }

  makeNode(uiContext: UIContext): FrameNode | null {
    this.rootNode = new FrameNode(uiContext);
    const renderNode = this.rootNode.getRenderNode();
    if (renderNode === null) {
      return this.rootNode;
    }
    if (renderNode) {
      renderNode.clearChildren()
      this.nodeArray.forEach((item) => {
        renderNode.appendChild(item)
      })
    }
    return this.rootNode;
  }
}

@Entry
@Component
struct Index {
  @State newNode:TextRenderNode = new TextRenderNode();
  @State nodeCV:MyNodeController = new MyNodeController()
  // frameNodeArr:Array<FrameNode> = []
  private matrix1 = matrix4.identity().setPolyToPoly({ src: [{x:0, y:0}, {x:vp2px(200), y:0}, {x:0, y:vp2px(200)}, {x:vp2px(200), y:vp2px(200)} ],
    dst:[{x:0, y:vp2px(50)}, {x:vp2px(200), y:0}, {x:0, y:vp2px(200)}, {x:vp2px(200), y:vp2px(200)}], pointCount:4})
  tempY = 0
  build() {
    Column() {
      Column() {
        NodeContainer(this.nodeCV)
          .width('100%')
          .height(200)
        // .transform(this.matrix1)
        Button('Invalidate')
          .onClick(() => {
            let frameNode = new MyFrameNode(this.getUIContext());
            // this.frameNodeArr.push(frameNode)
            let newNode = frameNode.getRenderNode()
            newNode!.frame = { x: 0, y: this.tempY, width: 200, height: 100 }
            newNode!.backgroundColor = Color.Red
            frameNode.commonAttribute.transform(this.matrix1)
            this.nodeCV.addMyNode(newNode!)
            this.nodeCV.rebuild()
            this.tempY += 100
          })
      }
      .width('100%')
      .height('100%')
    }
    .height('100%')
  }
}

可以使用自定义FrameNode，对每个FrameNode设置不同的矩阵变换
