在word文档中插入图片 [英] Insert picture in word document
问题描述
这是我第一次在 Apache POI 上工作，我要问的问题已经在这个网站上问过了，但没有给出明确的答案，所以我别无选择，只能接受你的帮助.
This is the first time I am working on Apache POI and the question which I am going to ask has been asked already on this site but no clear answer were given for them so I have no choice but to take all your help.
我正在尝试编写一个 Java 程序，该程序从一个文件夹中获取图像并将该图像插入到 Word 文档中.我正在为这个程序使用 Apache POI.我在这里发布我的代码.
I am trying to write a java program which takes images from one folder and insert that image into a word document. I am using Apache POI for this program. Here I am posting my code.
import java.io.*;
import java.util.*;
import org.apache.poi.util.IOUtils;
import org.apache.poi.xwpf.usermodel.*;
public class ImagesDoc
{
public static void main(String[] args) throws IOException
{
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("C:\\Users\\amitabh\\Pictures\\pics\\pool.jpg");
byte [] picbytes = IOUtils.toByteArray(pic);
docx.addPicture(picbytes, Document.PICTURE_TYPE_JPEG);
FileOutputStream out = new FileOutputStream("C:\\Users\\amitabh\\Pictures\\pics\\simple1.docx");
docx.write(out);
out.close();
pic.close();
}
}
我能够创建 word 文档文件，我也能够插入文本，但是 docx.addPicture(picbytes, Document.PICTURE_TYPE_JPEG); 行给我的错误是add转换为 docx".我已经为这个程序添加了所有可能的 jars.对于这个错误，我在网上搜索了很多，发现很多人都遇到了类似的问题.XWPFDocument 参考的addPicture"不起作用.请帮我解决这个问题.
I am able to create the word document file and I am able to insert the text as well but docx.addPicture(picbytes, Document.PICTURE_TYPE_JPEG); line is giving me the error as"add cast to docx". I have added all possible jars for this program. For this error I have searched all over the net and found that many people are having similar problem. "addPicture" for XWPFDocument reference is not working. Please help me to resolve this problem.
推荐答案
首先，我想指出 apache poi 提供的例子 - 链接，即正确的做法是
First, I would like to point out the example provided by apache poi - Link, i.e. the correct way to do it would be
doc.createParagraph().createRun().addPicture(new FileInputStream(imgFile), format, imgFile, Units.toEMU(200), Units.toEMU(200));
然而，仍然存在一个错误，在执行上述语句后导致 .docx 文件不可读.它可能很快就会解决，在这种情况下，上述声明将起作用.在此期间，有一个变通方法.
However, there is still an existing bug which renders the .docx file unreadable after executing the above statement. It might be resolved soon, in which case the above-mentioned statement will do the work. For the meantime, there is a work-around.
首先生成没有图片的docx文件.然后将此类 CustomXWPFDocument 添加到您的包中.
First, generate the docx file without any pictures. Then add this class CustomXWPFDocument to your package.
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");
}
}
然后，通过添加这样的图片来创建更新的文档:-
Then, create the updated document by adding your pictures like this :-
CustomXWPFDocument document = new CustomXWPFDocument(new FileInputStream(new File("C:\\Users\\Avarice\\Desktop\\doc1.docx")));
FileOutputStream fos = new FileOutputStream(new File("C:\\Users\\Avarice\\Desktop\\doc2.docx"));
String id = document.addPictureData(new FileInputStream(new File("C:\\Users\\Avarice\\Desktop\\thumbnail.jpg")), Document.PICTURE_TYPE_JPEG);
document.createPicture(id,document.getNextPicNameNumber(Document.PICTURE_TYPE_JPEG), 64, 64);
document.write(fos);
fos.flush();
fos.close();
您的构建路径中还应包含以下 jar:-
You should also have the following jars in your build path:-
poi-ooxml-schemas
poi-ooxml-schemas
