将PPT转化为PDF我的JAVA代码实现!

jacob的方法,足可以解决这个问题,但是我既然以前曾经做过报表,就想尝试不同的方法。


JACOB是一座连接JAVA和微软的桥,所有的解析由微软解析。POI是没有微软解析的那么原汁原味的,所以如果要求高的话,还是使用JACOB。


大致思路很简单,将PPT先转化为图片,然后将图片写入PDF。转化图片是用POI,操作PDF使用ITEX。不过这个方法的BUG就是转化图片的POI效果不是很好。


导入的包分别是:itextpdf-5.1.3.jar,poi-3.8-20120326.jar,poi-scratchpad-3.8-20120326.jar。



然后贴代码了:


代码没有进行参数统一,写两个方法:

package com.zzk.cn;

import java.awt.Dimension;
import java.io.File;
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.awt.Color;
import java.awt.Dimension;
import java.awt.Graphics2D;
import java.awt.geom.Rectangle2D;
import java.awt.image.BufferedImage;
import org.apache.poi.hslf.model.TextRun;
import org.apache.poi.hslf.record.Slide;
import org.apache.poi.hslf.usermodel.RichTextRun;
import org.apache.poi.hslf.usermodel.SlideShow;

public class PPTtoImage {
	public static void main(String[] args) {
		// 读入PPT文件
		File file = new File("D:/书本JVM总结7-9.ppt");
		doPPTtoImage(file);
	}

	public static boolean doPPTtoImage(File file) {
		boolean isppt = checkFile(file);
		if (!isppt) {
			System.out.println("你指定的文件不是ppt文档!");
			return false;
		}
		try {
			FileInputStream is = new FileInputStream(file);
			SlideShow ppt = new SlideShow(is);
			is.close();
			Dimension pgsize = ppt.getPageSize();
			org.apache.poi.hslf.model.Slide[] slide = ppt.getSlides();
			for (int i = 0; i < slide.length; i++) {
				System.out.print("第" + i + "页。");
				if (slide[i].getNotesSheet() != null
						&& slide[i].getNotesSheet().getTextRuns() != null) {
					// 获取第一个备注
					System.out.println("备注:"
							+ slide[i].getNotesSheet().getTextRuns()[0]
									.getText());
				}
				TextRun[] truns = slide[i].getTextRuns();
				for (int k = 0; k < truns.length; k++) {
					RichTextRun[] rtruns = truns[k].getRichTextRuns();
					for (int l = 0; l < rtruns.length; l++) {
						rtruns[l].setFontIndex(1);
						rtruns[l].setFontName("宋体");
						// 获取文本列表
						System.out.println(rtruns[l].getText());
					}
				}
				BufferedImage img = new BufferedImage(pgsize.width,
						pgsize.height, BufferedImage.TYPE_INT_RGB);
				Graphics2D graphics = img.createGraphics();
				graphics.setPaint(Color.white);
				graphics.fill(new Rectangle2D.Float(0, 0, pgsize.width,
						pgsize.height));
				slide[i].draw(graphics);
				// 这里设置图片的存放路径和图片的格式(jpeg,png,bmp等等),注意生成文件路径
				FileOutputStream out = new FileOutputStream("D:/testImage/pict_"
						+ (i + 1) + ".jpeg");
				javax.imageio.ImageIO.write(img, "jpeg", out);
				out.close();
			}
			System.out.println("ok");
			return true;
		} catch (FileNotFoundException e) {
			System.out.println(e);
		} catch (IOException e) {
			e.printStackTrace();
		}
		return false;
	}

	// function 检查文件是否为PPT
	public static boolean checkFile(File file) {
		boolean isppt = false;
		String filename = file.getName();
		String suffixname = null;
		if (filename != null && filename.indexOf(".") != -1) {
			suffixname = filename.substring(filename.indexOf("."));
			if (suffixname.equals(".ppt")) {
				isppt = true;
			}
			return isppt;
		} else {
			return isppt;
		}
	}
}


第二段代码:

package com.zzk.cn;

import java.io.FileOutputStream;
import java.io.IOException;

import com.itextpdf.text.Document;
import com.itextpdf.text.DocumentException;
import com.itextpdf.text.Image;
import com.itextpdf.text.pdf.PdfWriter;

public class ImagetoPDF {
    
    public static void main(String[] args) {
        
        System.out.println("Chapter 6 example 3: using a relative path for HTML");
        
        // step 1: creation of a document-object
        Document document = new Document();
        
        try {
            
            // step 2:
            // we create a writer that listens to the document
            // and directs a PDF-stream to a file
            
            PdfWriter.getInstance(document, new FileOutputStream("D:/测试图片.pdf"));
          //  HtmlWriter writer = HtmlWriter.getInstance(document, new FileOutputStream("Chap0603.html"));
            
          //  writer.setImagepath("../../images/kerstmis/");
            
            // step 3: we open the document
            document.open();
            
            for(int i=1;i<=7;i++) {
            // step 4: we add content
            Image jpg = Image.getInstance("D:/testImage/pict_"+i+".jpeg");
            jpg.scalePercent(50);
            document.add(jpg);
            }
            
        }
        catch(DocumentException de) {
            System.err.println(de.getMessage());
        }
        catch(IOException ioe) {
            System.err.println(ioe.getMessage());
        }
        
        // step 5: we close the document
        document.close();
    }
}
