从一个大神那里学来的，已测试无误

public static void main(String[] args) {
// 读入PPT文件
File file = new File("D:\\UPH.ppt");
doPPTtoImage(file);
}

public static boolean doPPTtoImage(File file) {
boolean isppt = checkFile(file);
if (!isppt) {
System.out.println("The image you specify don't exit!");
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++) {
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");
}
}
BufferedImage img = new BufferedImage(pgsize.width, pgsize.height,
BufferedImage.TYPE_INT_RGB);

Graphics2D graphics = img.createGraphics();
graphics.setPaint(Color.BLUE);
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
File path = new File("D:/images");
if (!path.exists()) {
path.mkdir();
}
FileOutputStream out = new FileOutputStream(path + "/" + (i + 1)
+ ".jpg");
javax.imageio.ImageIO.write(img, "jpeg", out);
out.close();
}
System.out.println("success!!");
return true;
} catch (FileNotFoundException e) {
System.out.println(e);
} catch (IOException e) {
}
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.lastIndexOf("."));
if (suffixname.equals(".ppt")) {
isppt = true;
}
return isppt;
} else {
return isppt;
}
}

}

这个就在Word上面就可以做的！当图片出现时，用：Ctrl+Alt+A→用鼠标框选图片→双击图片→退出后找一QQ对话框(借用、不发送)→粘贴→再另存桌面就是图片了。

用office2007打开后另存的时候在对话框另存名字的下面选word文档格式就ok了！
