如何在 Apache POI 中调整图像环绕样式
How to adjust image wrapping style in Apache POI
我必须创建一个文本后面有图像的 Word 文档 (docx)。我设法使用以下代码添加图像：
XWPFParagraph p = doc.createParagraph();
XWPFRun r = p.createRun();
String imgFile = "image.png";
XWPFPicture picture = r.addPicture(new FileInputStream(imgFile), XWPFDocument.PICTURE_TYPE_PNG, imgFile, Units.pixelToEMU(855), Units.pixelToEMU(776));
但我可以在任何地方找到如何将其发送到文本后面（有点像背景图片或水印）。
尝试下面的完整代码..
