OLE 物件

本頁內容簡介

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。

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 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。

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。

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。

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。

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()
