docx4j PDF 导出忽略 TextDirection

docx4j PDF export ignores TextDirection

我正在使用最新的 docx4j (3.3.7) 并生成 table,其中包含一个文本旋转 90 度的单元格。 docx 输出是正确的,但是当导出到 pdf 时,此单元格中的文本不会旋转,只是常规的从左到右的方向。

Plutext 的商业 PDF 转换器(默认启用)和 docx4j-export-fo.

的行为相同

如何强制旋转 table 单元格中的文本?

我用来在 table 单元格中旋转文本的代码(在 docx 中工作正常,在 pdf 导出期间被忽略):

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

我也试过这个,效果一样:

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

我正在使用以下方法导出为 PDF:

Docx4J.toPDF(wordprocessingMLPackage, fileOutputStream);

由于 XSL FO 具有 属性 引用导向,应该可以在 docx4j-export-fo 中实现:

https://github.com/plutext/docx4j-export-FO/commit/3b2c7423c25fe73bb5a85d9aa8755cce6e1aca8e and https://github.com/plutext/docx4j/commit/d8254cbf69d7bb3decaa94254946bd293c5d3ec0实现这个。

然而,结果并不完美;使用 FOP 2.3 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。

如果您进一步探索这个问题,您可能会得出一些额外的 fo 属性是必需的结论,或者它是 FOP 中的一个错误。请在此处的评论中分享您的发现。

顺便说一句,XHTML 输出中有类似的行为。
