OLE Object

What this page is about

Use Aspose.Slides for Python via Java to add, access, remove, and update OLE objects in PowerPoint and OpenDocument presentations.

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. 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.

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.

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.

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.

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()
