Remove images in .docx file

问题:

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);
                }
            }
            }
        }  

Exception:

回答1:

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);
    }
}

Try this :

        for (XWPFRun run : paragraph.getRuns())
                {
                     CTDrawing []  arr = run.getCTR().getDrawingArray();

                     for(int k=0; k<arr.length; k++)
                     {
                         run.getCTR().removeDrawing(k);
                     }

                }
