使用POI向word中添加图片
由于一次需要向word中添加多张图片，其中有图片存在重复，一开始使用的创建图片代码为：
xwpf.createPicture(xwpf.getAllPictures().size()-1, 80, 30,pargraph);
public void createPicture(int id, int width, int height,XWPFParagraph paragraph) {
final int EMU = 9525;
width *= EMU;
height *= EMU;
String blipId = getAllPictures().get(id).getPackageRelationship().getId();
CTInline inline = paragraph.createRun().getCTR().addNewDrawing().addNewInline();
String picXml = ""
+ ""
+ " "
+ " "
+ " " + " "
+ " "
+ " "
+ " "
+ " "
+ " "
+ " "
+ " "
+ " "
+ " "
+ " "
+ " "
+ " "
+ " "
+ " "
+ " " + " ";
// CTGraphicalObjectData graphicData =
inline.addNewGraphic().addNewGraphicData();
XmlToken xmlToken = null;
try {
xmlToken = XmlToken.Factory.parse(picXml);
} catch (XmlException xe) {
xe.printStackTrace();
}
inline.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");
}
上述代码对于重复的图片流不会第二次生成id，因此会造成第二次出现的图片被后续图片覆盖的情况。
因此，修改为如下处理方式，解决了重复图片的问题：
String ind = xwpf.addPictureData(is, XWPFDocument.PICTURE_TYPE_GIF); int id = xwpf.getNextPicNameNumber(XWPFDocument.PICTURE_TYPE_GIF); xwpf.createPicture(ind, id, 80, 30,pargraph);
public void createPicture(String blipId, int id, int width, int height,XWPFParagraph paragraph) {
final int EMU = 9525;
width *= EMU;
height *= EMU;
//String blipId = getAllPictures().get(id).getPackageRelationship().getId();
CTInline inline = paragraph.createRun().getCTR().addNewDrawing().addNewInline();
String picXml = "" +
"" +
" " +
" " +
" " +
" " +
" " +
" " +
" " +
" " +
" " +
" " +
" " +
" " +
" " +
" " +
" " +
" " +
" " +
" " +
" " +
" ";
// CTGraphicalObjectData graphicData =
inline.addNewGraphic().addNewGraphicData();
XmlToken xmlToken = null;
try {
xmlToken = XmlToken.Factory.parse(picXml);
} catch (XmlException xe) {
xe.printStackTrace();
}
inline.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给Word添加水印
Maven 引入依赖
org.apache.poi poi 3.17 org.apache.poi poi-ooxml 3.17
Java 代码：
package com.daydayup.study001.watermark;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import org.apache.poi.xwpf.model.XWPFHeaderFooterPolicy;
import org.apache.poi.xwpf.usermodel.XWPFDocument;
import org.apache.poi.xwpf.usermodel.XWPFHeader;
import org.apache.poi.xwpf.usermodel.XWPFParagraph;
import org.apache.poi.xwpf.usermodel.XWPFRun;
public class WatermarkForWord {
public static void main(String[] args) throws FileNotFoundException, IOException {
XWPFDocument doc= new XWPFDocument();
// the body content
XWPFParagraph paragraph = doc.createParagraph();
XWPFRun run=paragraph.createRun();
run.setText("The Body:");
// create header-footer
XWPFHeaderFooterPolicy headerFooterPolicy = doc.getHeaderFooterPolicy();
if (headerFooterPolicy == null) headerFooterPolicy = doc.createHeaderFooterPolicy();
// create default Watermark - fill color black and not rotated
headerFooterPolicy.createWatermark("Watermark");
// get the default header
// Note: createWatermark also sets FIRST and EVEN headers
// but this code does not updating those other headers
XWPFHeader header = headerFooterPolicy.getHeader(XWPFHeaderFooterPolicy.DEFAULT);
paragraph = header.getParagraphArray(0);
// get com.microsoft.schemas.vml.CTShape where fill color and rotation is set
org.apache.xmlbeans.XmlObject[] xmlobjects = paragraph.getCTP().getRArray(0).getPictArray(0).selectChildren(
new javax.xml.namespace.QName("urn:schemas-microsoft-com:vml", "shape"));
if (xmlobjects.length > 0) {
com.microsoft.schemas.vml.CTShape ctshape = (com.microsoft.schemas.vml.CTShape)xmlobjects[0];
// set fill color
ctshape.setFillcolor("#d8d8d8");
// set rotation
ctshape.setStyle(ctshape.getStyle() + ";rotation:315");
//System.out.println(ctshape);
}
doc.write(new FileOutputStream("CreateWordHeaderFooterWatermark.docx"));
doc.close();
}
}
