docx4j PDF导出忽略TextDirection

Question

我使用最新的docx4j (3.3.7)和generate表，它包含一个单元格，文本旋转90度。docx输出是正确的，但是当导出到pdf时，这个单元格中的文本不是旋转的，只有规则的左向右方向。

冥王星的商业PDF转换器(默认启用)和docx4j-export-fo也是如此。

如何强制表格单元格中的文本旋转？

用于在tableCell中旋转文本的代码(在docx中工作良好，在pdf导出过程中被忽略)：

TcPr tableCellProperties = tableCell.getTcPr();
if (tableCellProperties == null) {
    tableCellProperties = new TcPr();
    tableCell.setTcPr(tableCellProperties);
}
TextDirection td = new TextDirection();
td.setVal("tbRl");
tableCellProperties.setTextDirection(td);

我也尝试过这样做，效果也是一样：

TextDirection td = new TextDirection();
td.setVal("tbRl");
paragraph.setPPr(new PPr());
paragraph.getPPr().setTextDirection(td);

我使用以下方法导出PDF：

Docx4J.toPDF(wordprocessingMLPackage, fileOutputStream);

由于XSL FO具有面向属性的引用，因此应该可以在docx4j-export-fo中实现：

• What does reference-orientation really do?

https://github.com/plutext/docx4j-export-FO/commit/3b2c7423c25fe73bb5a85d9aa8755cce6e1aca8e和https://github.com/plutext/docx4j/commit/d8254cbf69d7bb3decaa94254946bd293c5d3ec0实现了这一点。

然而，结果是不完美的；用FOP2.3测试以下XSL-FO：

文本按预期旋转，但在一种情况下出现在单元格之外。

如果您进一步研究这一点，您可能会得出一些额外的fo属性是必需的，或者它是FOP中的一个bug。请在这里的评论中分享你的发现。

顺便说一句，XHTML输出中类似的行为。
