WPF UI线程状态(WPF UI Thread Status)

 您可能会遇到意外行为，因为您的子节点已在组内移动。 
 
 当您在x = 120 y = 140时创建图像时。当您将组位置设置为（例如）x = 100 y = 100时，图像将被放置在x = 210（120 + 100）y = 240（140 + 100）。 
 
 只需减少子元素的位置： 
 
      yoda = new Konva.Image({
        x: 5,
        y: 5,
        image: imageObj,
        width: 106,
        height: 118
      });

      group.add(border);
      group.add(yoda);

You may have unexpected behaviour because your children nodes are moved inside a group.
 
When you created the image in had x = 120 y = 140. When you set group position to (for example) x= 100 y = 100, image will be placed in x = 210 (120 + 100) y = 240 (140 + 100).
 
Just decrease positions of children elements:
 
      yoda = new Konva.Image({
        x: 5,
        y: 5,
        image: imageObj,
        width: 106,
        height: 118
      });

      group.add(border);
      group.add(yoda);
