如何使用Apache中的Apache POI XWPF將圖片添加到.docx文件

Question

我已經使用Java POI 3.7創建了一個簡單的docx-Document。 XWPF。然後，我使用方法XWPFDocument.addpicture(byte[] arg0, int arg1)添加了一張 的圖片。

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); 

由於docx文件大小增加，圖片被「物理地」添加到文檔;但它在MS Word中完全不顯示。似乎有文件中缺少圖片的引用。

這是怎麼回事？ apache POI如何處理圖片？網站上有更多的教程，XWPF幾乎沒有任何文檔或教程，它解釋了段落，運行等的處理。

我發現的唯一的東西在這裏：https://issues.apache.org/bugzilla/show_bug.cgi?id=49765但它沒有幫助。

非常感謝提前。

Answer 1

，你實際上已經提供了該錯誤鏈接有一個有效的解決方案： https://issues.apache.org/bugzilla/show_bug.cgi?id=49765#c15

它需要兩輪牛車的一些量，但我使用它，它肯定有效！

我已經使用docx4j，發現它工作。我嘗試使用興趣點，但無法使其工作。請找到使用docx4j的代碼。

public static void main(String[] args) throws Exception { 
    WordprocessingMLPackage wordMLPackage = WordprocessingMLPackage.createPackage(); 
    //wordMLPackage.getMainDocumentPart().addStyledParagraphOfText("Title", "Hello World"); 
    //wordMLPackage.getMainDocumentPart().addParagraphOfText("Text"); 
    java.io.InputStream is = new java.io.FileInputStream("path\\to\\images.jpg"); 
// commons-io.jar 
    byte[] bytes = IOUtils.toByteArray(is); 
    String filenameHint = null; 
    String altText = null; 
    int id1 = 0; 
    int id2 = 1; 
    org.docx4j.wml.P p = newImage(wordMLPackage, bytes,filenameHint, altText,id1, id2,6000 ); 
    // Now add our p to the document 
    wordMLPackage.getMainDocumentPart().addObject(p); 
    wordMLPackage.save(new java.io.File("helloworld.docx")); 
    is.close(); 
} 



public static org.docx4j.wml.P newImage(WordprocessingMLPackage wordMLPackage, 
     byte[] bytes, 
     String filenameHint, String altText, 
     int id1, int id2, long cx) throws Exception { 

     BinaryPartAbstractImage imagePart = BinaryPartAbstractImage.createImagePart(wordMLPackage, bytes); 

     Inline inline = imagePart.createImageInline(filenameHint, altText,id1, id2, cx,false); 

    // Now add the inline in w:p/w:r/w:drawing 
     org.docx4j.wml.ObjectFactory factory = new org.docx4j.wml.ObjectFactory(); 
     org.docx4j.wml.P p = factory.createP(); 
     org.docx4j.wml.R run = factory.createR();    
     p.getContent().add(run);  
     org.docx4j.wml.Drawing drawing = factory.createDrawing();    
     run.getContent().add(drawing);    
     drawing.getAnchorOrInline().add(inline); 

     return p; 

}

我知道這個職位是很老了，但還是我張貼的答案，使所有那些誰正在尋找這個答案可以使用它。 爲了在word文檔中插入圖片，你必須編寫兩個程序。第一個是： -

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(); 

    } 

} 

現在，這裏我在此代碼中使用「CustomeXwPFDocument」，所以你必須添加其他的.java類在你的包，你不會得到通過任何jar文件的任何進口。 「CustomXWPFDocument」類的代碼如下所示： -

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"); 
    } 
} 

此程序使用POI 3.9 jars。最好的網址是： - http://www.apache.org/dyn/closer.cgi/poi/release/bin/poi-bin-3.9-20121203.zip

現在你已經準備好飛行了。祝你好運。

優雅的解決方案來了，檢查出： https://issues.apache.org/bugzilla/show_bug.cgi?id=55476

您可以等到我的補丁被接受，並釋放或嘗試應用補丁最新的POI SVN結帳（http://poi.apache.org/subversion.html，只讀訪問鏈接將工作）和從源頭構建興趣點罐子。

通過tsd.tom建議將工作的方法：

XWPFParagraph par = docx.createParagraph(); 
XWPFRun run = par.createRun(); 
run.addPicture(pic, XWPFDocument.PICTURE_TYPE_JPEG, "logo.JPG",300,300);

@Pradeep Your code 

    public static void main(String[] args) throws Exception { 
    WordprocessingMLPackage wordMLPackage = WordprocessingMLPackage.createPackage(); 
    //wordMLPackage.getMainDocumentPart().addStyledParagraphOfText("Title", "Hello World"); 
    //wordMLPackage.getMainDocumentPart().addParagraphOfText("Text"); 
    java.io.InputStream is = new java.io.FileInputStream("path\\to\\images.jpg"); 
// commons-io.jar 
    byte[] bytes = IOUtils.toByteArray(is); 
    String filenameHint = null; 
    String altText = null; 
    int id1 = 0; 
    int id2 = 1; 
    org.docx4j.wml.P p = newImage(wordMLPackage, bytes,filenameHint, altText,id1, id2,6000 ); 
    // Now add our p to the document 
    wordMLPackage.getMainDocumentPart().addObject(p); 
    wordMLPackage.save(new java.io.File("helloworld.docx")); 
    is.close(); 
} 



public static org.docx4j.wml.P newImage(WordprocessingMLPackage wordMLPackage, 
     byte[] bytes, 
     String filenameHint, String altText, 
     int id1, int id2, long cx) throws Exception { 

     BinaryPartAbstractImage imagePart = BinaryPartAbstractImage.createImagePart(wordMLPackage, bytes); 

     Inline inline = imagePart.createImageInline(filenameHint, altText,id1, id2, cx,false); 

    // Now add the inline in w:p/w:r/w:drawing 
     org.docx4j.wml.ObjectFactory factory = new org.docx4j.wml.ObjectFactory(); 
     org.docx4j.wml.P p = factory.createP(); 
     org.docx4j.wml.R run = factory.createR();    
     p.getContent().add(run);  
     org.docx4j.wml.Drawing drawing = factory.createDrawing();    
     run.getContent().add(drawing);    
     drawing.getAnchorOrInline().add(inline); 

     return p; 

works , but all the above codes does not work, i tried it personally 

thanks, a lot. 

Answer 6

因爲XWPFRun。給AddPicture不起作用（它XDOC損壞文件），我設法想象這樣的：

private void addPicture(final String fileName, final int id, int width, int height, final XWPFRun run) 
{ 
    FileInputStream fileInputStream = null; 

    try 
    { 
     fileInputStream = new FileInputStream("/home/maq/ebworkspace/TeamForge_Tools/" + fileName); 
     final String blipId = run.getDocument().addPictureData(fileInputStream, Document.PICTURE_TYPE_JPEG); 

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

     final CTInline inline = run.getCTR().addNewDrawing().addNewInline(); 

     final 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; 
     xmlToken = XmlToken.Factory.parse(picXml); 
     inline.set(xmlToken); 
     //graphicData.set(xmlToken); 

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

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

     final CTNonVisualDrawingProps docPr = inline.addNewDocPr(); 
     docPr.setId(id); 
     docPr.setName("Picture " + id); 
     docPr.setDescr("Generated"); 
    } 
    catch (final Exception e) 
    { 
     // TODO Auto-generated catch block 
     e.printStackTrace(); 
    } 
    finally 
    { 
     //close streams 
     if (fileInputStream != null) 
     { 
      try 
      { 
       fileInputStream.close(); 
      } 
      catch (final IOException ioEx) 
      { 
       //can be ignored 
      } 
     } 
    } 

} 

和運行例如：

addPicture(filePath, xdoc.getNextPicNameNumber(Document.PICTURE_TYPE_JPEG), 100, 50, xRun);
