我正在尝试解析一个包含几个矩形的IDML传播，总共8个。矩形从一个原始矩形复制粘贴，旋转并定位在跨页上。

在IDML文件中，所有矩形看起来都有相同的原点，只是每个元素的变换不同。我正在试图弄清楚如何将整个嵌套的噩梦转换为一组整齐的中心点定向坐标和维度。

下面是扩展XML：

代码语言：javascript

我猜测PathPointArray中的PathPointTypes表示对象在其内部坐标空间中的坐标(独立于变换)。然后，属性ItemTransform="-0.7071067811865476 -0.7071067811865476 0.7071067811865476 -0.7071067811865476 -1422.0440983174867 1054.726131672103“将用于影响上层上的对象几何体。因此，这里的坏消息是，假设跨页也没有旋转/倾斜，那么您必须掌握转换矩阵的计算，以获得跨页坐标中的页面项目的最终坐标。否则，您将需要完成第二组计算。
