如何将图片在java中添加到文档的.docx与Apache POI XWPF [英] how to add a picture to a .docx document with Apache POI XWPF in java

问题描述

我创建了一个简单的docx，文档，使用Java POI 3.7。 XWPF。然后，我通过增加一个图片
使用方法 XWPFDocument.addpicture（字节[]为arg0，ARG1 INT）。

I've created a simple docx-Document, using Java POI 3.7. XWPF. Then, I added a picture by using the Method XWPFDocument.addpicture(byte[] arg0, int arg1).

XWPFDocument docx = new XWPFDocument();  
XWPFParagraph par = docx.createParagraph();  
XWPFRun run = par.createRun();
run.setText("Hello, World. This is my first java generated docx-file. Have fun.");
run.setFontSize(13);

InputStream pic = new FileInputStream("logo.jpg");
byte [] picbytes = IOUtils.toByteArray(pic);
docx.addPicture(picbytes, Document.PICTURE_TYPE_JPEG);

由于的docx文件大小的增长，照片添加身体的文件;但它不是在所有的MS Word显示。好像有就是图片中的文档中缺少一个参考。

Since file size of the docx grows, the picture was added "physically" to the document; but it is not displayed at all in MS Word. Seems like there is a reference to the picture missing in the document.

什么是做到这一点的方式呢？如何处理图片与Apache POI做了什么？哪里是在网络上的教程，有几乎没有文件或教程在所有的XWPF，这也解释了处理段，运行速度等。

What's the way to do this? How is picture handling done with apache POI? And where are more tutorials on the web, there is nearly no documents or tutorials at all for XWPF, which explains handling of paragraphs, runs, etc.

我发现这个唯一的一点是在这里：<一href=\"https://issues.apache.org/bugzilla/show_bug.cgi?id=49765\">https://issues.apache.org/bugzilla/show_bug.cgi?id=49765但它并没有帮助的。

The only thing I found about this is here: https://issues.apache.org/bugzilla/show_bug.cgi?id=49765 but it does not help at all.

提前非常感谢。

推荐答案

我知道这个职位是很老，但仍然我张贴的答案，使所有那些谁正在寻找这个答案可以使用它。
对于Word文档中插入的图片，你必须写两个程序。第一个是： -

I know this post is very old but still I am posting the answer so that all those who are searching for this answer can use it. For inserting the picture in the word document you have to write two programs. The first one is :-

package org.word.POI;

import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;

import org.apache.poi.openxml4j.exceptions.InvalidFormatException;
import org.apache.poi.xwpf.usermodel.Document;
import org.apache.poi.xwpf.usermodel.XWPFDocument;

public class TestCustom
{

    public static void main(String []a) throws FileNotFoundException, IOException, InvalidFormatException
    {

        CustomXWPFDocument document = new CustomXWPFDocument(new FileInputStream(new File("C:\\Users\\amitabh\\Documents\\Apache POI\\Word File\\new.doc")));
        FileOutputStream fos = new FileOutputStream(new File("C:\\Users\\amitabh\\Documents\\Apache POI\\Word File\\new.doc"));

        String blipId = document.addPictureData(new FileInputStream(new File("C:\\Users\\amitabh\\Pictures\\pics\\3.jpg")), Document.PICTURE_TYPE_JPEG);

        System.out.println(document.getNextPicNameNumber(Document.PICTURE_TYPE_JPEG));

        //System.out.println(document.getNextPicNameNumber(Document.PICTURE_TYPE_JPEG));
        document.createPicture(blipId,document.getNextPicNameNumber(Document.PICTURE_TYPE_JPEG), 500, 500);


        document.write(fos);
        fos.flush();
        fos.close();

    }

}

现在在这里我已经在这个code使用的CustomeXwPFDocument等等，你必须添加其他的.java类你的包，你不会得到通过任何jar文件的进口。在code为CustomXWPFDocument级是这样的： -

Now here I have used "CustomeXwPFDocument" in this code and you will not get any imports through any jar file so you have to add another .java class in your package. the code for "CustomXWPFDocument" class goes like this:-

package org.word.POI;

import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.xmlbeans.XmlException;
import org.apache.xmlbeans.XmlToken;
import org.openxmlformats.schemas.drawingml.x2006.main.CTNonVisualDrawingProps;
import org.openxmlformats.schemas.drawingml.x2006.main.CTPositiveSize2D;
import org.openxmlformats.schemas.drawingml.x2006.wordprocessingDrawing.CTInline;

import java.io.IOException;
import java.io.InputStream;

public class CustomXWPFDocument extends XWPFDocument
{
    public CustomXWPFDocument(InputStream in) throws IOException
    {
        super(in);
    }

    public void createPicture(String blipId,int id, int width, int height)
    {
        final int EMU = 9525;
        width *= EMU;
        height *= EMU;
        //String blipId = getAllPictures().get(id).getPackageRelationship().getId();


        CTInline inline = createParagraph().createRun().getCTR().addNewDrawing().addNewInline();

        String picXml = "" +
                "<a:graphic xmlns:a=\"http://schemas.openxmlformats.org/drawingml/2006/main\">" +
                "   <a:graphicData uri=\"http://schemas.openxmlformats.org/drawingml/2006/picture\">" +
                "      <pic:pic xmlns:pic=\"http://schemas.openxmlformats.org/drawingml/2006/picture\">" +
                "         <pic:nvPicPr>" +
                "            <pic:cNvPr id=\"" + id + "\" name=\"Generated\"/>" +
                "            <pic:cNvPicPr/>" +
                "         </pic:nvPicPr>" +
                "         <pic:blipFill>" +
                "            <a:blip r:embed=\"" + blipId + "\" xmlns:r=\"http://schemas.openxmlformats.org/officeDocument/2006/relationships\"/>" +
                "            <a:stretch>" +
                "               <a:fillRect/>" +
                "            </a:stretch>" +
                "         </pic:blipFill>" +
                "         <pic:spPr>" +
                "            <a:xfrm>" +
                "               <a:off x=\"0\" y=\"0\"/>" +
                "               <a:ext cx=\"" + width + "\" cy=\"" + height + "\"/>" +
                "            </a:xfrm>" +
                "            <a:prstGeom prst=\"rect\">" +
                "               <a:avLst/>" +
                "            </a:prstGeom>" +
                "         </pic:spPr>" +
                "      </pic:pic>" +
                "   </a:graphicData>" +
                "</a:graphic>";

        //CTGraphicalObjectData graphicData = inline.addNewGraphic().addNewGraphicData();
        XmlToken xmlToken = null;
        try
        {
            xmlToken = XmlToken.Factory.parse(picXml);
        }
        catch(XmlException xe)
        {
            xe.printStackTrace();
        }
        inline.set(xmlToken);
        //graphicData.set(xmlToken);

        inline.setDistT(0);
        inline.setDistB(0);
        inline.setDistL(0);
        inline.setDistR(0);

        CTPositiveSize2D extent = inline.addNewExtent();
        extent.setCx(width);
        extent.setCy(height);

        CTNonVisualDrawingProps docPr = inline.addNewDocPr();
        docPr.setId(id);
        docPr.setName("Picture " + id);
        docPr.setDescr("Generated");
    }
}

使用POI 3.9罐子对这一计划。最好的网址是： -

Use POI 3.9 jars for this program. The best URL is:- http://www.apache.org/dyn/closer.cgi/poi/release/bin/poi-bin-3.9-20121203.zip

现在你是箭在弦上。祝您好运。

Now you are ready to fly. Best of luck.
