# OLE 物件

> 使用 Aspose.Slides for Python via Java 在 PowerPoint 與 OpenDocument 簡報中新增、存取、移除與更新 OLE 物件。

Source: https://docs.aspose.com/slides/zh-hant/python-java/examples/elements/ole-object/


本文示範如何將檔案嵌入為 OLE 物件，並使用 **Aspose.Slides for Python via Java** 更新其資料。

請依照[Installation](/slides/zh-hant/python-java/installation/) 中的說明安裝套件。每個範例皆在啟動 JVM 之前匯入 `asposeslides`，然後在 JVM 運作後匯入 API。

## **新增 OLE 物件**
將 PDF 檔案嵌入簡報中。

```python
from pathlib import Path

import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import OleEmbeddedDataInfo, Presentation

presentation = Presentation()
try:
    slide = presentation.getSlides().get_Item(0)

    pdf_data = Path("doc.pdf").read_bytes()
    java_pdf_data = jpype.JArray(jpype.JByte)(pdf_data)
    data_info = OleEmbeddedDataInfo(java_pdf_data, "pdf")
    ole_frame = slide.getShapes().addOleObjectFrame(20, 20, 50, 50, data_info)
finally:
    presentation.dispose()
```

## **存取 OLE 物件**
取得投影片上第一個 OLE 物件框架。

```python
from pathlib import Path

import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import OleEmbeddedDataInfo, OleObjectFrame, Presentation

presentation = Presentation()
try:
    slide = presentation.getSlides().get_Item(0)

    pdf_data = Path("doc.pdf").read_bytes()
    java_pdf_data = jpype.JArray(jpype.JByte)(pdf_data)
    data_info = OleEmbeddedDataInfo(java_pdf_data, "pdf")
    slide.getShapes().addOleObjectFrame(20, 20, 50, 50, data_info)

    first_ole_frame = None
    for shape in slide.getShapes():
        if isinstance(shape, OleObjectFrame):
            first_ole_frame = shape
            break

    if first_ole_frame is None:
        print("The slide contains no OLE object frames.")
finally:
    presentation.dispose()
```

## **移除 OLE 物件**
從投影片中刪除已嵌入的 OLE 物件。

```python
from pathlib import Path

import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import OleEmbeddedDataInfo, Presentation

presentation = Presentation()
try:
    slide = presentation.getSlides().get_Item(0)

    pdf_data = Path("doc.pdf").read_bytes()
    java_pdf_data = jpype.JArray(jpype.JByte)(pdf_data)
    data_info = OleEmbeddedDataInfo(java_pdf_data, "pdf")
    ole_frame = slide.getShapes().addOleObjectFrame(20, 20, 50, 50, data_info)

    slide.getShapes().remove(ole_frame)
finally:
    presentation.dispose()
```

## **更新 OLE 物件資料**
取代已存在 OLE 物件中嵌入的資料。

```python
from pathlib import Path

import jpype
import asposeslides

if not jpype.isJVMStarted():
    jpype.startJVM()

from asposeslides.api import OleEmbeddedDataInfo, Presentation

presentation = Presentation()
try:
    slide = presentation.getSlides().get_Item(0)

    pdf_data = Path("doc.pdf").read_bytes()
    java_pdf_data = jpype.JArray(jpype.JByte)(pdf_data)
    data_info = OleEmbeddedDataInfo(java_pdf_data, "pdf")
    ole_frame = slide.getShapes().addOleObjectFrame(20, 20, 50, 50, data_info)

    new_data = Path("Picture.png").read_bytes()
    java_new_data = jpype.JArray(jpype.JByte)(new_data)
    new_data_info = OleEmbeddedDataInfo(java_new_data, "png")
    ole_frame.setEmbeddedData(new_data_info)
finally:
    presentation.dispose()
```
