PPT幻灯片中支持将文档作为OLE对象插入到PPT幻灯片指定位置，在幻灯片中可直接点击该对象，打开或编辑等。下面以插入Excel工作簿文档为例，介绍如何来插入到幻灯片。

### **程序运行环境** ###

*  编译环境：IDEA（jdk 1.8.0）
 *  测试文档：Excel 2013（.xlsx）、Power Point（.pptx）
 *  Office Jar包：[Free Spire.Office for Java 3.9.0][]

关于如何导入jar，参考如下步骤：

### **Java示例代码** ###

import com.spire.presentation.FileFormat;
    import com.spire.presentation.drawing.IImageData;
    import com.spire.xls.*;
    import com.spire.presentation.*;
    
    import javax.imageio.ImageIO;
    import java.awt.*;
    import java.awt.image.BufferedImage;
    import java.io.File;
    import java.io.FileInputStream;
    
    
    public class AddOLE {
        public static void main(String[] args) throws Exception {
            //新建PowerPoint文档
            Presentation ppt = new Presentation();
    
            //加载Excel文档，将指定单元格数据保存为图片
            Workbook workbook = new Workbook();
            workbook.loadFromFile("test.xlsx");
            Worksheet sheet = workbook.getWorksheets().get(0);
            sheet.saveToImage("image.png",1,1,8,7);//将指定单元格数据范围保存为图片
    
            //加载保存的表格图片（作为OLE对象图标）
            File file = new File("image.png");
            BufferedImage image = ImageIO.read(file);
            IImageData oleImage = ppt.getImages().append(image);
            Rectangle rec = new Rectangle(120, 30, image.getWidth()/2, image.getHeight()/2);
    
            //将Excel数据保存到流
            File oldFile = new File("test.xlsx");
            FileInputStream inputStream = new FileInputStream(oldFile);
            byte[] data = new byte[(int)oldFile.length()];
            inputStream.read(data,0,data.length);
    
            //将Excel文档作为OLE对象插入到幻灯片
            IOleObject oleObject = ppt.getSlides().get(0).getShapes().appendOleObject("excel", data, rec);
            oleObject.getSubstituteImagePictureFillFormat().getPicture().setEmbedImage(oleImage);
            oleObject.setProgId("Excel.Sheet.12");
    
            //保存文档
            ppt.saveToFile("EmbedExcelAsOLE.pptx", FileFormat.PPTX_2013);
            inputStream.close();
        }
    }

OLE对象添加结果：
