xsl-fo - 引用导向到底有什么作用？

Question

我必须使用 FOP 渲染 pfd，并且必须旋转一些图像。然而，结果看起来并不像我期望的那样。所以，这是我的问题(我不知何故无法找到一个好的文档来为我澄清这个问题):

如果我定义

fo:block-container reference-orientation="90" width="100" height="200"

这会旋转整个容器(有效地导致尺寸为 200x100 的渲染框)，还是只会旋转容器的内容(让容器本身以 100x200 尺寸渲染)？

Answer 1

它将旋转整个容器。

这是宽度小于高度然后旋转 90 度的示例...
