使用 POI XWPF 将图像位置和倾斜设置为 word .docx 文档

Question

我使用XWPF addPicture 在word文档中添加了如下图片，

XWPFParagraph p3 = document.createParagraph();
XWPFRun r3 = p3.createRun();
imgFile = "C:\poi-3.9\pictures\Picture4.jpeg";
try {
r3.addPicture(new FileInputStream(imgFile), format, imgFile, Units.toEMU(500), Units.toEMU(80)); // 200x200 pixels
}catch (Exception e){
  System.out.println (e.getMessage());
}

现在我想把它设置到一个特定的位置并倾斜它，这样它看起来像这样...

有什么方法可以使用 XWPF 运行或任何其他方法来完成。谢谢。

我自己解决了。基本上 word 文档是一种 zip 文件。如果我们将 word 文件扩展名重命名为 .zip 并打开 document.xml 文件，我们可以看到图像实际上是如何使用 xml 格式定位的。这是我采取的步骤。

Create a word document with the required image and set image position manually ()

Rename the file extension as .zip from .docx , extract the zip file.

Navigate and open document.xml which is present in the word folder of the extracted zip.

Search of the image name (here my image name is picture4)

Get the Horizontal and Vertical offset , extent cx and cy, relative height and other parameters position from the xml, I have marked them in bold in the xml snippet below.

<w:body>
        <w:p>
            <w:bookmarkStart w:id="0" w:name="_GoBack"/>
            <w:bookmarkEnd w:id="0"/>
            <w:r>
                <w:drawing>
                    <wp:anchor distT="0" distB="0" distL="**114300**" distR="**114300**" simplePos="0" relativeHeight="**251658240**" behindDoc="1" locked="0" layoutInCell="1" allowOverlap="1">
                        <wp:simplePos x="0" y="0"/>
                        <wp:positionH relativeFrom="column">
                            <wp:posOffset>**-2256790**</wp:posOffset>
                        </wp:positionH>
                        <wp:positionV relativeFrom="paragraph">
                            <wp:posOffset>**-1823085**</wp:posOffset>
                        </wp:positionV>
                        <wp:extent cx=**"3448050"** cy=**"3619500"**/>
                        <wp:effectExtent l="0" t="0" r="0" b="0"/>
                        <wp:wrapNone/>
                        <wp:docPr id="4" name="Drawing 0" descr="**Picture4**"/>
                        <wp:cNvGraphicFramePr>

设置相同的锚点xml

String anchorXML = "<wp:anchor xmlns:wp=\"http://schemas.openxmlformats.org/drawingml/2006/wordprocessingDrawing\" " +"distT=\"0\" distB=\"0\" distL=\"114300\" distR=\"114300\" simplePos=\"0\" relativeHeight=\"251658240\" behindDoc=\"1\" locked=\"0\" layoutInCell=\"1\" allowOverlap=\"1\">"

   +"<wp:simplePos x=\"0\" y=\"0\"/>"

   +"<wp:positionH relativeFrom=\"column\"><wp:posOffset>-1800000</wp:posOffset></wp:positionH>"
   +"<wp:positionV relativeFrom=\"paragraph\"><wp:posOffset>-1800000</wp:posOffset></wp:positionV>"

   + "<wp:extent cx=\"3448050\" cy=\"3619500\"/>"
   +"<wp:effectExtent l=\"0\" t=\"0\" r=\"6350\" b=\"6350\"/>"
   +"  <wp:simplePos x=\"0\" y=\"0\"/><wp:positionH relativeFrom=\"column\"><wp:posOffset>-1800000</wp:posOffset></wp:positionH><wp:positionV relativeFrom=\"paragraph\"><wp:posOffset>-1800000</wp:posOffset></wp:positionV><wp:extent cx=\"3448050\" cy=\"3619500\"/><wp:effectExtent l=\"0\" t=\"0\" r=\"0\" b=\"0\"/><wp:wrapNone/> "
   +"<wp:docPr id=\"1\" name=\"Drawing 0\" descr=\""+drawingDescr+"\"/><wp:cNvGraphicFramePr/>"
   +"</wp:anchor>";

这里是添加图像和位置的示例代码，我们可以参数化设置偏移量和其他xml参数的方法。
