How to set page orientation for a Word document?

Question

I use Apache POI XWPF to create and process MS Word documents. But I did not find in the documentation how to change the page orientation.

Obviously, this method should do this:

 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 does not work correctly. I can set the page orientation to landscape, and when I read the page orientation in the code, I get a landscape. Fine. But if I open the saved document, I have a portrait format. This parameter does not work. What could be the problem?

As a workaround, I have to start working with a blank document created manually in landscape or portrait format. But I want to create documents programmatically from scratch in the right orientation.

For example, the HSSF and XSSF POIs have functionality for switching between landscape and portrait modes. This is the setLandscape () interface method org.apache.poi.ss.usermodel.PrintSetup .

But what about XWPF or HWPF ?

Answer 1

You were on the right track. The landscape orientation setting describes the general orientation of the paper, but paper size will still be required. Your CTPageSz object does not already have this.

This means that in addition to your setOrient call, you need to set setW and setH. These calls are taken by BigIntegers, which are 1/20 Point representatives. Therefore, for landscape paper like LETTER, you simply:

 pageSize.setW(BigInteger.valueOf(15840)); pageSize.setH(BigInteger.valueOf(12240)); 

For Word to recognize it as landscape, the width must be greater than the height. You still want to save the setOrient call if you want it to work correctly when printing. A.

Here are some common paper sizes in points from https://www.gnu.org/software/gv/manual/html_node/Paper-Keywords-and-paper-size-in-points.html you should take them and multiply by twenty. to use in the above methods

Answer 2

The answer is correct.

I just needed to add additional dependencies in order to access the CTPageSz class.

 // SBT config "org.apache.poi" % "poi-ooxml" % "4.1.0", // Base library "org.apache.poi" % "ooxml-schemas" % "1.4", // required to access CTPageSz
