HarmonyOS 鸿蒙Next AR Engine中图片坐标转屏幕坐标

arFrame.acquireCameraImage()

获得了图片，现在我知道图片上的一些坐标点，怎么转为对应的屏幕坐标呢？

ARCore：

我在google的arcore中可以通过以下方法实现：

/
 * Transforms a list of 2D coordinates from one 2D coordinate system to another 2D coordinate
 * system.
 
 * <p>Same as {@link
 * #transformCoordinates2d(com.google.ar.core.Coordinates2d,java.nio.FloatBuffer,com.google.ar.core.Coordinates2d,java.nio.FloatBuffer)},
 * but taking float arrays.
 
 * @param inputCoordinates The coordinate system used by {@code inputVertices2d}.
 * @param inputVertices2d Input 2D vertices to transform.
 * @param outputCoordinates The coordinate system to convert to.
 * @param outputVertices2d Buffer to put the transformed 2D vertices into.
 /
public void transformCoordinates2d(
    com.google.ar.core.Coordinates2d inputCoordinates,
    float[] inputVertices2d,
    com.google.ar.core.Coordinates2d outputCoordinates,
    float[] outputVertices2d) {
  // Method contents removed.
}

public enum Coordinates2d {
  / CPU image, (x,y) normalized to [0.0f, 1.0f] range. /
  IMAGE_NORMALIZED,
  / CPU image, (x,y) in pixels. */
  IMAGE_PIXELS,
  /
   * OpenGL Normalized Device Coordinates, display-rotated, (x,y) normalized to [-1.0f, 1.0f] range.
   /
  OPENGL_NORMALIZED_DEVICE_COORDINATES,
  /* GPU texture coordinates, (s,t) normalized to [0.0f, 1.0f] range. /
  TEXTURE_NORMALIZED,
  /* GPU texture, (x,y) in pixels. /
  TEXTURE_TEXELS,
  /* Android view, display-rotated, (x,y) in pixels. /
  VIEW,
  /* Android view, display-rotated, (x,y) normalized to [0.0f, 1.0f] range. */
  VIEW_NORMALIZED;
}

所以可以很轻松地进行任意的坐标转换，比如cameraImage坐标转屏幕坐标，cameraImage坐标转depthImage坐标…

我想知道华为ar engine如何完成这件事呢？

arFrame.transformDisplayUvCoords 这个方法貌似不奏效
