在 Java 中使用 Apache POI XWPF 在同一个 word 文档中横向和纵向页面 [英] Landscape and portrait pages in the same word document using Apache POI XWPF in Java

问题描述

我正在尝试使用 Java 和 Apache POI 库来创建包含一些横向页面和一些纵向页面的 Word 文档.我可以改变所有页面的方向，但有没有办法只改变其中一些页面的方向?我尝试使用不同的部分和正文，但无济于事.

I am trying to use Java and the Apache POI library to create a word document that contained some landscape and some portrait pages. I can change the orientation of all the pages, but is there a way to change just the orientation of some of them? I have tried using different sections and bodies, but to no avail.

目前我已经编写了一个函数，它将 XWPFDocument 作为输入并更改新主体的方向.我本来希望改变新正文的方向不会影响以前的页面，但会影响整个文档.

At the moment I have written a function that takes a XWPFDocument as input and changes the orientation of a new body. I had hoped changing the orientation for new body would not affect the previous pages, but it affects the entire document.

private void changeOrientation(XWPFDocument document, String orientation){
    CTDocument1 doc = document.getDocument();
    CTBody body = doc.addNewBody();
    body.addNewSectPr();
    CTSectPr section = body.getSectPr();
    if(!section.isSetPgSz()) {
        section.addNewPgSz();
    }
    CTPageSz pageSize = section.getPgSz();
    if(orientation.equals("landscape")){
        pageSize.setOrient(STPageOrientation.LANDSCAPE);
        pageSize.setW(BigInteger.valueOf(842 * 20));
        pageSize.setH(BigInteger.valueOf(595 * 20));
    }
    else{
        pageSize.setOrient(STPageOrientation.PORTRAIT);
        pageSize.setH(BigInteger.valueOf(842 * 20));
        pageSize.setW(BigInteger.valueOf(595 * 20));
    }
}

谢谢！

推荐答案

原来需要一个 CTPPr(分节符)，可以用以下代码完成:

Turns out a CTPPr (a section break) is needed, which can be done with the following code:

private void changeOrientation(XWPFDocument document, String orientation){
    CTDocument1 doc = document.getDocument();
    CTBody body = doc.getBody();
    CTSectPr section = body.addNewSectPr();
    XWPFParagraph para = document.createParagraph();
    CTP ctp = para.getCTP();
    CTPPr br = ctp.addNewPPr();
    br.setSectPr(section);
    CTPageSz pageSize = section.getPgSz();
    if(orientation.equals("landscape")){
        pageSize.setOrient(STPageOrientation.LANDSCAPE);
        pageSize.setW(BigInteger.valueOf(842 * 20));
        pageSize.setH(BigInteger.valueOf(595 * 20));
    }
    else{
        pageSize.setOrient(STPageOrientation.PORTRAIT);
        pageSize.setH(BigInteger.valueOf(842 * 20));
        pageSize.setW(BigInteger.valueOf(595 * 20));
    }
}

但是，这只能使用一次，因此页面不能改变方向.必须首先是所有横向页面，最后是纵向页面，反之亦然.

However, this only works once, so pages can't alternate orientations. It has to be all the landscape pages first and portrait last or vice versa.
