使用 Python 透過 Java 管理簡報超連結

簡介

超連結是對物件、資料或位置的參照。PowerPoint 簡報中常見的超連結包括:

  • 文字、圖形或媒體中的網站連結
  • 投影片連結

Aspose.Slides for Python via Java 讓您可以執行許多與簡報超連結相關的任務。

新增 URL 超連結

將 URL 超連結新增至文字

此 Python 程式碼示範如何將網站超連結新增至文字:

import jpype
import asposeslides

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

from asposeslides.api import Hyperlink, Presentation, SaveFormat, ShapeType

presentation = Presentation()
try:
    shape = presentation.getSlides().get_Item(0).getShapes().addAutoShape(ShapeType.Rectangle, 100, 100, 600, 50, False)
    shape.addTextFrame("Aspose: File Format APIs")

    portion_format = shape.getTextFrame().getParagraphs().get_Item(0).getPortions().get_Item(0).getPortionFormat()
    portion_format.setHyperlinkClick(Hyperlink("https://www.aspose.com/"))
    portion_format.getHyperlinkClick().setTooltip("More than 70% Fortune 100 companies trust Aspose APIs")
    portion_format.setFontHeight(32)

    presentation.save("presentation-out.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()

將 URL 超連結新增至圖形或框架

此 Python via Java 示例程式碼示範如何將網站超連結新增至圖形:

import jpype
import asposeslides

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

from asposeslides.api import Hyperlink, Presentation, SaveFormat, ShapeType

presentation = Presentation()
try:
    shape = presentation.getSlides().get_Item(0).getShapes().addAutoShape(ShapeType.Rectangle, 100, 100, 600, 50)

    shape.setHyperlinkClick(Hyperlink("https://www.aspose.com/"))
    shape.getHyperlinkClick().setTooltip("More than 70% Fortune 100 companies trust Aspose APIs")

    presentation.save("pres-out.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()

將 URL 超連結新增至媒體

Aspose.Slides 允許您將超連結新增至圖像、音訊和影片檔案。

此示例程式碼示範如何將超連結新增至 圖像

import jpype
import asposeslides

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

from asposeslides.api import Hyperlink, Images, Presentation, SaveFormat, ShapeType

presentation = Presentation()
try:
    # 新增影像至簡報
    image = Images.fromFile("image.png")
    try:
        picture = presentation.getImages().addImage(image)
    finally:
        image.dispose()
    # 在第1張投影片上建立圖片框,基於先前新增的影像
    picture_frame = presentation.getSlides().get_Item(0).getShapes().addPictureFrame(ShapeType.Rectangle, 10, 10, 100, 100, picture)

    picture_frame.setHyperlinkClick(Hyperlink("https://www.aspose.com/"))
    picture_frame.getHyperlinkClick().setTooltip("More than 70% Fortune 100 companies trust Aspose APIs")

    presentation.save("pres-out.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()

此示例程式碼示範如何將超連結新增至 音訊檔案

from pathlib import Path

import jpype
import asposeslides

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

from asposeslides.api import Hyperlink, Presentation, SaveFormat

presentation = Presentation()
try:
    audio_data = Path("audio.mp3").read_bytes()
    java_audio_data = jpype.JArray(jpype.JByte)(audio_data)
    audio = presentation.getAudios().addAudio(java_audio_data)
    audio_frame = presentation.getSlides().get_Item(0).getShapes().addAudioFrameEmbedded(10, 10, 100, 100, audio)

    audio_frame.setHyperlinkClick(Hyperlink("https://www.aspose.com/"))
    audio_frame.getHyperlinkClick().setTooltip("More than 70% Fortune 100 companies trust Aspose APIs")

    presentation.save("pres-out.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()

此示例程式碼示範如何將超連結新增至 影片

from pathlib import Path

import jpype
import asposeslides

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

from asposeslides.api import Hyperlink, Presentation, SaveFormat

presentation = Presentation()
try:
    video_data = Path("video.avi").read_bytes()
    java_video_data = jpype.JArray(jpype.JByte)(video_data)
    video = presentation.getVideos().addVideo(java_video_data)
    video_frame = presentation.getSlides().get_Item(0).getShapes().addVideoFrame(10, 10, 100, 100, video)

    video_frame.setHyperlinkClick(Hyperlink("https://www.aspose.com/"))
    video_frame.getHyperlinkClick().setTooltip("More than 70% Fortune 100 companies trust Aspose APIs")

    presentation.save("pres-out.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()

使用超連結建立目錄

由於超連結允許您加入對物件或位置的參照,您可以利用它們建立目錄。

此示例程式碼示範如何使用超連結建立目錄:

import jpype
import asposeslides

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

from asposeslides.api import FillType, Paragraph, Portion, Presentation, SaveFormat, ShapeType

Color = jpype.JClass("java.awt.Color")

presentation = Presentation()
try:
    first_slide = presentation.getSlides().get_Item(0)
    second_slide = presentation.getSlides().addEmptySlide(first_slide.getLayoutSlide())

    content_table = first_slide.getShapes().addAutoShape(ShapeType.Rectangle, 40, 40, 300, 100)
    content_table.getFillFormat().setFillType(FillType.NoFill)
    content_table.getLineFormat().getFillFormat().setFillType(FillType.NoFill)
    content_table.getTextFrame().getParagraphs().clear()

    paragraph = Paragraph()
    paragraph.getParagraphFormat().getDefaultPortionFormat().getFillFormat().setFillType(FillType.Solid)
    paragraph.getParagraphFormat().getDefaultPortionFormat().getFillFormat().getSolidFillColor().setColor(Color.BLACK)
    paragraph.setText("Title of slide 2 .......... ")

    link_portion = Portion()
    link_portion.setText("Page 2")
    link_portion.getPortionFormat().getHyperlinkManager().setInternalHyperlinkClick(second_slide)

    paragraph.getPortions().add(link_portion)
    content_table.getTextFrame().getParagraphs().add(paragraph)

    presentation.save("link_to_slide.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()

格式化超連結

顏色

使用 Hyperlink.setColorSource 屬性於 Hyperlink 類別,您可以設定超連結的顏色,也能從超連結取得顏色資訊。此功能於 PowerPoint 2019 首次推出,因此屬性相關的變更不適用於較舊的 PowerPoint 版本。

此示例程式碼示範在同一投影片中加入不同顏色的超連結的操作:

import jpype
import asposeslides

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

from asposeslides.api import FillType, Hyperlink, HyperlinkColorSource, Presentation, SaveFormat, ShapeType

Color = jpype.JClass("java.awt.Color")

presentation = Presentation()
try:
    colored_link_shape = presentation.getSlides().get_Item(0).getShapes().addAutoShape(ShapeType.Rectangle, 100, 100, 450, 50, False)
    colored_link_shape.addTextFrame("This is a sample of colored hyperlink.")
    portion_format = colored_link_shape.getTextFrame().getParagraphs().get_Item(0).getPortions().get_Item(0).getPortionFormat()
    portion_format.setHyperlinkClick(Hyperlink("https://www.aspose.com/"))
    portion_format.getHyperlinkClick().setColorSource(HyperlinkColorSource.PortionFormat)
    portion_format.getFillFormat().setFillType(FillType.Solid)
    portion_format.getFillFormat().getSolidFillColor().setColor(Color.RED)

    default_link_shape = presentation.getSlides().get_Item(0).getShapes().addAutoShape(ShapeType.Rectangle, 100, 200, 450, 50, False)
    default_link_shape.addTextFrame("This is a sample of usual hyperlink.")
    default_link_shape.getTextFrame().getParagraphs().get_Item(0).getPortions().get_Item(0).getPortionFormat().setHyperlinkClick(Hyperlink("https://www.aspose.com/"))

    presentation.save("presentation-out-hyperlink.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()

從簡報中移除超連結

從文字中移除超連結

此 Python 程式碼示範如何從簡報投影片的文字中移除超連結:

import jpype
import asposeslides

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

from asposeslides.api import Presentation, SaveFormat, AutoShape

presentation = Presentation("presentation.pptx")
try:
    slide = presentation.getSlides().get_Item(0)
    for shape in slide.getShapes():
        if isinstance(shape, AutoShape):
            text_frame = shape.getTextFrame()
            if text_frame is not None:
                for paragraph in text_frame.getParagraphs():
                    for portion in paragraph.getPortions():
                        portion.getPortionFormat().getHyperlinkManager().removeHyperlinkClick()

    presentation.save("pres-removed-hyperlinks.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()

從圖形或框架中移除超連結

此 Python 程式碼示範如何從簡報投影片的圖形中移除超連結:

import jpype
import asposeslides

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

from asposeslides.api import Presentation, SaveFormat

presentation = Presentation("presentation.pptx")
try:
    slide = presentation.getSlides().get_Item(0)
    for shape in slide.getShapes():
        shape.getHyperlinkManager().removeHyperlinkClick()
    presentation.save("pres-removed-hyperlinks.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()

可變的超連結

Hyperlink 類別是可變的。使用此類別,您可以變更以下屬性的值:

此程式碼片段示範如何將超連結新增至投影片,並之後編輯其工具提示:

import jpage
import asposeslides

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

from asposeslides.api import Hyperlink, Presentation, SaveFormat, ShapeType

presentation = Presentation()
try:
    shape = presentation.getSlides().get_Item(0).getShapes().addAutoShape(ShapeType.Rectangle, 100, 100, 600, 50, False)
    shape.addTextFrame("Aspose: File Format APIs")

    portion_format = shape.getTextFrame().getParagraphs().get_Item(0).getPortions().get_Item(0).getPortionFormat()
    portion_format.setHyperlinkClick(Hyperlink("https://www.aspose.com/"))
    portion_format.getHyperlinkClick().setTooltip("More than 70% Fortune 100 companies trust Aspose APIs")
    portion_format.setFontHeight(32)

    # 更改已新增超連結的工具提示
    portion_format.getHyperlinkClick().setTooltip("Aspose: the File Format APIs")

    presentation.save("presentation-out.pptx", SaveFormat.Pptx)
finally:
    presentation.dispose()

HyperlinkQueries 支援的屬性

您可以從定義了超連結的簡報、投影片或文字中存取 HyperlinkQueries

HyperlinkQueries 類別支援以下方法與屬性:

常見問題

如何建立不僅指向投影片,而是指向「區段」或區段第一張投影片的內部導覽?

PowerPoint 中的區段是投影片的分組;導覽在技術上仍指向特定投影片。若要「導覽至區段」,通常會連結到該區段的第一張投影片。

我可以將超連結附加到母片元素,使其在所有投影片上都有效嗎?

可以。母片和版面配置元素支援超連結。這類連結會出現在子投影片上,並在投影片放映時可點選。

匯出為 PDF、HTML、圖像或影片時,超連結會被保留嗎?

PDFHTML 中,會保留連結;通常會保持超連結。然而,匯出至 imagesvideo 時,因為這些格式(點陣框架/影片)不支援超連結,點擊功能將不會保留。
