Deleting images in a .docx file
Do we have the ability to remove images from a .docx
file in java using xwpfdocument
? Please answer me as I have been trying to do this for the past 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);
}
}
}
}
An exception:
Exception in thread "main" java.lang.IndexOutOfBoundsException

If you get IndexOutOfBoundsException
on a call where you are trying to remove item # 0, then your list is clearly empty. So either do a void check on all the blueprints of your object Run
, or use a for loop that won't run if yours is List<CTDrawing>
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);
}
}
