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(); } }
