How to set page orientation for Word document?
提问by Kapelchik
I use Apache POI XWPFto create and handle MS Worddocuments. But I didn't find in the documentation how to change the page orientation.
我使用Apache POI XWPF创建和处理MS Word文档。但是我没有在文档中找到如何更改页面方向。
Apparently this way should make it:
显然这种方式应该做到：
XWPFDocument doc = new XWPFDocument();
CTDocument1 document = doc.getDocument();
CTBody body = document.getBody();
if (!body.isSetSectPr()) {
body.addNewSectPr();
}
CTSectPr section = body.getSectPr();
if(!section.isSetPgSz()) {
section.addNewPgSz();
}
CTPageSz pageSize = section.getPgSz();
pageSize.setOrient(STPageOrientation.LANDSCAPE);
But this method doesn't work properly. I can set the page orientation to landscape, and when I read the page orientation in the code, I get landscape. All right. But if I open the saved document I've portrait format. This setting doesn't work in fact. What could be the problem?
但是这种方法不能正常工作。我可以将页面方向设置为横向，当我在代码中读取页面方向时，我得到横向。好的。但是，如果我打开保存的文档，我会使用纵向格式。这个设置实际上不起作用。可能是什么问题呢？
As a workaround, I'm forced to start work with a blank document created manually in landscape or portrait format. But I want to create documents programmatically from scratch in needed orientation.
作为一种解决方法，我不得不开始使用以横向或纵向格式手动创建的空白文档。但我想以所需的方向从头开始以编程方式创建文档。
For instance POI HSSF and XSSFhave functionality to toggle between landscape and portrait mode. It's setLandscape()method of org.apache.poi.ss.usermodel.PrintSetupinterface.
例如，POI HSSF 和 XSSF具有在横向和纵向模式之间切换的功能。它是接口的setLandscape()方法org.apache.poi.ss.usermodel.PrintSetup。
But what about XWPFor HWPF?
但是XWPF或HWPF呢？

You were very much on the right path. Setting the orientation to landscape describes the general orientation of the paper, but will still need the sizeof the paper. Your CTPageSz object doesn't have that yet.
你走在正确的道路上。将方向设置为横向描述了纸张的一般方向，但仍需要纸张的尺寸。您的 CTPageSz 对象还没有。
This means in addition to your setOrient call, you'll need to both setW and setH. These calls take BigIntegers that are representative of 1/20 Point. For a landscaped LETTER type paper therefore, you'll just:
这意味着除了 setOrient 调用之外，您还需要 setW 和 setH。这些调用采用代表 1/20 点的 BigInteger。因此，对于景观信纸类型的纸张，您只需：
pageSize.setW(BigInteger.valueOf(15840));
pageSize.setH(BigInteger.valueOf(12240));
For Word to recognize it as Landscaped, the width must be greater than the height. You still want to keep the setOrient call as well if you want it to behave properly when going to print.
为了让 Word 将其识别为 Landscaped，宽度必须大于高度。如果您希望它在打印时正常运行，您仍然希望保留 setOrient 调用。
Here's some common paper sizes in points from https://www.gnu.org/software/gv/manual/html_node/Paper-Keywords-and-paper-size-in-points.htmlyou should take these and multiply them by twenty to use in the above method calls

Answer is right.
答案是对的。
I just had to add extra dependencies to be able to access CTPageSz class.
我只需要添加额外的依赖项就可以访问 CTPageSz 类。
// SBT config
"org.apache.poi" % "poi-ooxml" % "4.1.0", // Base library
"org.apache.poi" % "ooxml-schemas" % "1.4", // required to access CTPageSz
