This article demonstrates how to embed a file as an OLE object and update its data using **Aspose.Slides for Python via Java**.

Install the package as described in [Installation](/slides/python-java/installation/). Each example imports `asposeslides` before starting the JVM, then imports the API after the JVM is running.

## **Add an OLE Object**

Embed a PDF file into the presentation.

```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()
```

## **Access an OLE Object**

Retrieve the first OLE object frame on a slide.

```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()
```

## **Remove an OLE Object**

Delete an embedded OLE object from the slide.

```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()
```

## **Update OLE Object Data**

Replace the data embedded in an existing OLE object.

```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()
```
