本文演示了如何将文件嵌入为 OLE 对象并使用 **Aspose.Slides for Java** 更新其数据。

## **添加 OLE 对象**

将 PDF 文件嵌入到演示文稿中。

```java
static void addOleObject() throws IOException {
    Presentation presentation = new Presentation();
    try {
        ISlide slide = presentation.getSlides().get_Item(0);

        byte[] pdfData = Files.readAllBytes(Paths.get("doc.pdf"));
        IOleEmbeddedDataInfo dataInfo = new OleEmbeddedDataInfo(pdfData, "pdf");
        IOleObjectFrame oleFrame = slide.getShapes().addOleObjectFrame(20, 20, 50, 50, dataInfo);
    } finally {
        presentation.dispose();
    }
}
```

## **访问 OLE 对象**

检索幻灯片上的第一个 OLE 对象框架。

```java
static void accessOleObject() throws IOException {
    Presentation presentation = new Presentation();
    try {
        ISlide slide = presentation.getSlides().get_Item(0);

        byte[] pdfData = Files.readAllBytes(Paths.get("doc.pdf"));
        IOleEmbeddedDataInfo dataInfo = new OleEmbeddedDataInfo(pdfData, "pdf");
        IOleObjectFrame oleFrame = slide.getShapes().addOleObjectFrame(20, 20, 50, 50, dataInfo);

        IOleObjectFrame firstOleFrame = null;
        for (IShape shape : slide.getShapes()) {
            if (shape instanceof IOleObjectFrame) {
                firstOleFrame = (IOleObjectFrame) shape;
                break;
            }
        }
    } finally {
        presentation.dispose();
    }
}
```

## **移除 OLE 对象**

从幻灯片中删除嵌入的 OLE 对象。

```java
static void removeOleObject() throws IOException {
    Presentation presentation = new Presentation();
    try {
        ISlide slide = presentation.getSlides().get_Item(0);

        byte[] pdfData = Files.readAllBytes(Paths.get("doc.pdf"));
        IOleEmbeddedDataInfo dataInfo = new OleEmbeddedDataInfo(pdfData, "pdf");
        IOleObjectFrame oleFrame = slide.getShapes().addOleObjectFrame(20, 20, 50, 50, dataInfo);
        
        slide.getShapes().remove(oleFrame);
    } finally {
        presentation.dispose();
    }
}
```

## **更新 OLE 对象数据**

替换现有 OLE 对象中嵌入的数据。

```java
static void updateOleObjectData() throws IOException {
    Presentation presentation = new Presentation();
    try {
        ISlide slide = presentation.getSlides().get_Item(0);
        
        byte[] pdfData = Files.readAllBytes(Paths.get("doc.pdf"));
        OleEmbeddedDataInfo dataInfo = new OleEmbeddedDataInfo(pdfData, "pdf");
        IOleObjectFrame oleFrame = slide.getShapes().addOleObjectFrame(20, 20, 50, 50, dataInfo);

        byte[] newData = Files.readAllBytes(Paths.get("Picture.png"));
        OleEmbeddedDataInfo newDataInfo = new OleEmbeddedDataInfo(newData, "png");
        oleFrame.setEmbeddedData(newDataInfo);
    } finally {
        presentation.dispose();
    }
}
```
