Objek OLE

Tentang apa halaman ini

Gunakan Aspose.Slides for Python via Java untuk menambahkan, mengakses, menghapus, dan memperbarui objek OLE dalam presentasi PowerPoint dan OpenDocument.

Artikel ini menunjukkan cara menyematkan file sebagai objek OLE dan memperbarui datanya menggunakan Aspose.Slides for Python via Java.

Instal paket seperti yang dijelaskan pada Installation. Setiap contoh mengimpor asposeslides sebelum memulai JVM, kemudian mengimpor API setelah JVM berjalan.

Menambahkan Objek OLE

Menyematkan file PDF ke dalam presentasi.

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()

Mengakses Objek OLE

Mengambil frame objek OLE pertama pada sebuah 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()

Menghapus Objek OLE

Menghapus objek OLE yang disematkan dari 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()

Memperbarui Data Objek OLE

Mengganti data yang disematkan dalam objek OLE yang ada.

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()
