使用Apache POI在DOCX中更改图像布局或换行

Question

我以编程方式将图像粘贴到docx中。但结果是布局不适合我。面临着缺乏文件的问题。我需要改变图像包装（布局）。例如，我现在有这样一个：

但要这样：

UPD1:我做的：遍历段落，然后遍历运行，找到带有特殊书签的特定运行。在此运行中，我添加图片：

XWPFPicture pic =  run.addPicture(
        new ByteArrayInputStream(picSource),
        Document.PICTURE_TYPE_PNG,
        "pic",
        Units.toEMU(100),
        Units.toEMU(30));

org.openxmlformats.schemas.drawingml.x2006.wordprocessingDrawing.CTAnchor

    CTWrapTight ctWrapTight = currentRun.getCTR().getDrawingList().get(0).addNewAnchor().addNewWrapTight();
 CTWrapPath ctWrapPath = ctWrapTight.addNewWrapPolygon();

 CTPoint2D ctStart = ctWrapPath.addNewStart();
 ctStart.setX(0L);
 ctStart.setY(0L);

 CTPoint2D ctLineTo1 = ctWrapPath.addNewLineTo();
 CTPoint2D ctLineTo2 = ctWrapPath.addNewLineTo();
 CTPoint2D ctLineTo3 = ctWrapPath.addNewLineTo();

 ctLineTo1.setX(21384L);
 ctLineTo1.setY(20520L);

 ctLineTo2.setX(21384L);
 ctLineTo2.setY(0L);

 ctLineTo3.setX(0L);
 ctLineTo3.setY(0L);

ctWrapTight.setWrapText(STWrapText.BOTH_SIDES);

虽然您已经找到了要使用的正确类--CTAnchor和后继类--但还需要考虑Anchor的XML模式定义。这说明需要的责任元素比定义包装的元素多得多。因此，使用org.openxmlformats.schemas.drawingml.x2006中的一个类一个类，您可能正在编写页面式代码。对于这类问题，我首选的解决方案是提供xml，所有需要的元素都由一些变量更新。然后可以解析这个XML以获得所需的对象。

示例：

import java.io.FileOutputStream;
import java.io.FileInputStream;
import java.io.InputStream;

import org.apache.poi.xwpf.usermodel.*;

import org.apache.poi.util.Units;

import org.openxmlformats.schemas.wordprocessingml.x2006.main.CTDrawing;
import org.openxmlformats.schemas.drawingml.x2006.main.CTGraphicalObject;
import org.openxmlformats.schemas.drawingml.x2006.wordprocessingDrawing.CTAnchor;

public class WordInsertPictures {

 private static CTAnchor getAnchorWithGraphic(CTGraphicalObject graphicalobject, 
                                              String drawingDescr, int width, int height,
                                              int left, int top) throws Exception {

  String anchorXML = 
   "<wp:anchor xmlns:wp=\"http://schemas.openxmlformats.org/drawingml/2006/wordprocessingDrawing\" "
  +"simplePos=\"0\" relativeHeight=\"0\" behindDoc=\"1\" locked=\"0\" layoutInCell=\"1\" allowOverlap=\"1\">"
  +"<wp:simplePos x=\"0\" y=\"0\"/>"
  +"<wp:positionH relativeFrom=\"column\"><wp:posOffset>"+left+"</wp:posOffset></wp:positionH>"
  +"<wp:positionV relativeFrom=\"paragraph\"><wp:posOffset>"+top+"</wp:posOffset></wp:positionV>"
  +"<wp:extent cx=\""+width+"\" cy=\""+height+"\"/>"
  +"<wp:effectExtent l=\"0\" t=\"0\" r=\"0\" b=\"0\"/>"
  +"<wp:wrapTight wrapText=\"bothSides\">"
  +"<wp:wrapPolygon edited=\"0\">"
  +"<wp:start x=\"0\" y=\"0\"/>"
  +"<wp:lineTo x=\"0\" y=\"21600\"/>" //Square polygon 21600 x 21600 leads to wrap points in fully width x height
  +"<wp:lineTo x=\"21600\" y=\"21600\"/>"// Why? I don't know. Try & error ;-).
  +"<wp:lineTo x=\"21600\" y=\"0\"/>"
  +"<wp:lineTo x=\"0\" y=\"0\"/>"
  +"</wp:wrapPolygon>"
  +"</wp:wrapTight>"
  +"<wp:docPr id=\"1\" name=\"Drawing 0\" descr=\""+drawingDescr+"\"/><wp:cNvGraphicFramePr/>"

  CTDrawing drawing = CTDrawing.Factory.parse(anchorXML);
  CTAnchor anchor = drawing.getAnchorArray(0);
  anchor.setGraphic(graphicalobject);
  return anchor;  
 }

 public static void main(String[] args) throws Exception {

  XWPFDocument document = new XWPFDocument();
  XWPFParagraph paragraph = document.createParagraph();
  XWPFRun run = paragraph.createRun();

  run.setText("The picture in line: ");

  InputStream in = new FileInputStream("samplePict.jpeg");
  run.addPicture(in, Document.PICTURE_TYPE_JPEG, "samplePict.jpeg", Units.toEMU(100), Units.toEMU(30));
  in.close();  

  run.setText(" text after the picture.");

  paragraph = document.createParagraph();

  run = paragraph.createRun();
  in = new FileInputStream("samplePict.jpeg");
  run.addPicture(in, Document.PICTURE_TYPE_JPEG, "samplePict.jpeg", Units.toEMU(100), Units.toEMU(30));

  drawing.setAnchorArray(new CTAnchor[]{anchor});
  drawing.removeInline(0);

  run = paragraph.createRun();
  run.setText("The previous picture is anchored wrapTight. The previous picture is anchored wrapTight. The previous picture is anchored wrapTight. The previous picture is anchored wrapTight. The previous picture is anchored wrapTight. The previous picture is anchored wrapTight.");

  document.write(new FileOutputStream("WordInsertPictures.docx"));
  document.close();
