您好：我使用aspose-words-21.5.0-jdk17.jar版本生成word。生成的word包含header和footer，还有body。分别是三个table，每个table的的cell都设置了段落。然后把header、body和footer中某一个段落放入到集合中，遍历集合move到对应段落，然后插入对应段落的shape。以下代码注释了计算坐标的代码就可以正常运行。
但是现在有这样的问题：我需要在插入shape的时候重新计算shape的大小和相对位置，因为有可能会超过当前的word页面，所以我需要计算需要插入shape的段落的坐标（x，y）。然后去计算新的相对位置。出入body中的段落计算没有问题，但是传入header和footer中的段落，计算的时候就报错了。不清楚师什么原因。请帮忙指出错误原因？并且提供计算header和footer中段落的坐标（x, y）。感谢。
如有问题随时给我留言，感谢。
