删除.docx文件中的图像 [英] Remove images in .docx file

问题描述

我们是否可以选择使用 xwpfdocument 从java中的 .docx 文件中删除图片？因为我试图在过去一周内做这件事，请回复我。
代码尝试：

Do we have the option to remove pictures from .docx file in java using xwpfdocument? Please reply me since I'm trying to do it for past one week. Code tried:

public static void imageProcess(XWPFDocument document) throws IOException
    {
        List<XWPFPictureData> pic=document.getAllPictures();
        Iterator<XWPFPictureData> iterator=pic.iterator();      
        if (pic.size()>0)
        {   
            for (XWPFParagraph para : document.getParagraphs())
            { 
                List<XWPFRun> runs = para.getRuns();
                for( XWPFRun run : runs ){
                    run.getCTR().removeDrawing(0);
                }
            }
            }
        }  

异常：

 Exception in thread "main" java.lang.IndexOutOfBoundsException

推荐答案

如果你得到 IndexOutOfBoundsException 在您尝试删除项目＃0的调用中，那么您的列表显然是空的。因此要么对运行对象中的所有绘图进行空白检查，要么使用for循环 - 如果你的 List< CTDrawing> ; 为空。

If you get an IndexOutOfBoundsException on a call where you try to remove item #0, then your list is obviously empty. So either do an emptiness check on all the drawings in your Run object, or use a for loop - which won't execute if your List<CTDrawing> is empty.

for (XWPFRun run : runs) {
    CTR ctr = run.getCTR();
    List<CTDrawing> lst = ctr.getDrawingList();
    for (int i = 0; i < lst.size(); i++) {
        ctr.removeDrawing(i);
    }
}
