Question

我用kinect开始了旅程，我遇到了一些问题，我尝试从教程中学习并选择这一个here，但我对DrawTrackedBoneLine和DrawClipedEdges的声明有问题应该如何声明正常工作

private void DrawBone(Joint jointFrom, Joint jointTo)
    {
        Brush bone = null;
        Brush TrackedBone = new SolidColorBrush(Color.FromArgb(132, 54, 63, 78));
        Brush NonTracked = new SolidColorBrush(Color.FromArgb(45, 36, 23, 12));
        if (jointFrom.TrackingState == JointTrackingState.NotTracked ||
        jointTo.TrackingState == JointTrackingState.NotTracked)
        {
            return; // nothing to draw, one of the joints is not tracked
        }

        if (jointFrom.TrackingState == JointTrackingState.Inferred ||
        jointTo.TrackingState == JointTrackingState.Inferred)
        {

           DrawNonTrackedBoneLine (jointFrom.Position, jointTo.Position);  // Draw thin lines if either one of the joints is inferred
        }

        if (jointFrom.TrackingState == JointTrackingState.Tracked &&
        jointTo.TrackingState == JointTrackingState.Tracked)
        {
            DrawTrackedBoneLine(jointFrom.Position, jointTo.Position);  // Draw bold lines if the joints are both tracked
        }
    }

    private void RenderClippedEdges(Skeleton skeleton)
    {  

        if (skeleton.ClippedEdges.HasFlag(FrameEdges.Bottom))
        {
            DrawClippedEdges(FrameEdges.Bottom); // Make the border red to show the user is reaching the border
        }

        if (skeleton.ClippedEdges.HasFlag(FrameEdges.Top))
        {
            DrawClippedEdges(FrameEdges.Top);
        }

        if (skeleton.ClippedEdges.HasFlag(FrameEdges.Left))
        {
            DrawClippedEdges(FrameEdges.Left);
        }

        if (skeleton.ClippedEdges.HasFlag(FrameEdges.Right))
        {
            DrawClippedEdges(FrameEdges.Right);
        }
    }

我选择并尝试使用画笔，但它不起作用，它说“当前上下文中不存在名称'DrawTrackedBoneLine'”显然视觉是正确的，但如何解决它

Answer 1

您尚未声明函数DrawTrackedBoneLine，因此它“在当前上下文中不存在”。我认为msdn上的代码只是一个例子，你必须自己解决如何绘图的问题。

首先声明函数：

private void DrawTrackedBoneLine(SkeletonPoint positionFrom, SkeletonPoint positionTo)
{
    // Code goes here
}

private void DrawNonTrackedBoneLine(SkeletonPoint positionFrom, SkeletonPoint positionTo)
{
    // Code goes here
}

Kinect正确陈述绘图功能
