C# 在Kinect骨骼上放置图像

我目前有一个功能正常的Kinect骨架。在骨骼上，我想放置角色的手臂、腿、头部等的图像。我将如何进行此操作？我想我在画骨头的时候一定要添加图像，但除此之外，我不知道该怎么做。这是我绘制骨骼的函数。任何帮助都将不胜感激

 private void DrawBonesAndJoints(DrawingContext drawingContext)
        {
            if (this.ShowBones)
            {
                // Render Torso
                this.DrawBone(drawingContext, JointType.Head, JointType.ShoulderCenter);
                this.DrawBone(drawingContext, JointType.ShoulderCenter, JointType.ShoulderLeft);
                this.DrawBone(drawingContext, JointType.ShoulderCenter, JointType.ShoulderRight);
                this.DrawBone(drawingContext, JointType.ShoulderCenter, JointType.Spine);
                this.DrawBone(drawingContext, JointType.Spine, JointType.HipCenter);
                this.DrawBone(drawingContext, JointType.HipCenter, JointType.HipLeft);
                this.DrawBone(drawingContext, JointType.HipCenter, JointType.HipRight);

                // Left Arm
                this.DrawBone(drawingContext, JointType.ShoulderLeft, JointType.ElbowLeft);
                this.DrawBone(drawingContext, JointType.ElbowLeft, JointType.WristLeft);
                this.DrawBone(drawingContext, JointType.WristLeft, JointType.HandLeft);

                this.DrawBone(drawingContext, JointType.WristRight, JointType.HandRight);

                this.DrawBone(drawingContext, JointType.AnkleRight, JointType.FootRight);
            }

            if (this.ShowJoints)
            {
                // Render Joints
                foreach (JointMapping joint in this.JointMappings.Values)
                {

                    switch (joint.Joint.TrackingState)

                            drawBrush = this.trackedJointBrush;
                            break;
                        case JointTrackingState.Inferred:
                            drawBrush = this.inferredJointBrush;
                            break;
                    }

                    if (drawBrush != null)
                    {
                        drawingContext.DrawEllipse(drawBrush, null, joint.MappedPoint, JointThickness * this.ScaleFactor, JointThickness * this.ScaleFactor);
                    }
                }
            }
        }

首先通过一些基本的动画程序，如在骨骼跟踪场景中。 . 它包含您想要的内容，例如在骨骼上绘制图像
