使用 Python 管理簡報中的超連結

簡介

超連結是指向外部資源、物件或資料項目,或檔案內特定位置的參照。PowerPoint 簡報中常見的超連結類型包括:

  • 內嵌於文字、圖形或媒體中的網站連結
  • 連結至投影片

Aspose.Slides for Python via .NET 可在簡報中執行各種與超連結相關的操作。

新增 URL 超連結

本節說明在使用 Aspose.Slides 時,如何將 URL 超連結加入投影片元素。包括將連結位址指派給文字、圖形與圖片,確保簡報播放時的順暢導覽。

將 URL 超連結加入文字

以下程式碼範例示範如何將網站超連結加入文字:

import aspose.slides as slides

with slides.Presentation() as presentation:
    slide = presentation.slides[0]

    shape = slide.shapes.add_auto_shape(slides.ShapeType.RECTANGLE, 100, 100, 600, 50, False)
    shape.add_text_frame("Aspose: File Format APIs")
    
    text_portion = shape.text_frame.paragraphs[0].portions[0]

    text_portion.portion_format.hyperlink_click = slides.Hyperlink("https://www.aspose.com/")
    text_portion.portion_format.hyperlink_click.tooltip = "More than 70% of Fortune 100 companies trust Aspose APIs."

    presentation.save("output.pptx", slides.export.SaveFormat.PPTX)

將 URL 超連結加入圖形或框格

以下程式碼範例示範如何將網站超連結加入圖形:

import aspose.slides as slides

with slides.Presentation() as presentation:
    slide = presentation.slides[0]

    shape = slide.shapes.add_auto_shape(slides.ShapeType.RECTANGLE, 100, 100, 600, 50)

    shape.hyperlink_click = slides.Hyperlink("https://www.aspose.com/")
    shape.hyperlink_click.tooltip = "More than 70% of Fortune 100 companies trust Aspose APIs."

    presentation.save("output.pptx", slides.export.SaveFormat.PPTX)

將 URL 超連結加入媒體

Aspose.Slides 允許您為影像、音訊與影片檔案加入超連結。

以下程式碼範例示範如何為影像加入超連結:

import aspose.slides as slides

with slides.Presentation() as presentation:
    slide = presentation.slides[0]

    # 將圖像新增至簡報。
    with open("image.jpeg", "rb") as image_stream:
        image_data = image_stream.read()
        image = presentation.images.add_image(image_data)

    # 在投影片 1 上使用先前加入的圖像建立圖片框架。
    picture_frame = slide.shapes.add_picture_frame(slides.ShapeType.RECTANGLE, 10, 10, 100, 100, image)

    picture_frame.hyperlink_click = slides.Hyperlink("https://www.aspose.com/")
    picture_frame.hyperlink_click.tooltip = "More than 70% of Fortune 100 companies trust Aspose APIs."

    presentation.save("output.pptx", slides.export.SaveFormat.PPTX)

以下程式碼範例示範如何為音訊檔案加入超連結:

import aspose.slides as slides

with slides.Presentation() as presentation:
    slide = presentation.slides[0]

    with open("audio.mp3", "rb") as audio_stream:
        audio_data = audio_stream.read()
        audio = presentation.audios.add_audio(audio_data)
        
    audio_frame = slide.shapes.add_audio_frame_embedded(10, 10, 100, 100, audio)

    audio_frame.hyperlink_click = slides.Hyperlink("https://www.aspose.com/")
    audio_frame.hyperlink_click.tooltip = "More than 70% of Fortune 100 companies trust Aspose APIs."

    presentation.save("output.pptx", slides.export.SaveFormat.PPTX)

以下程式碼範例示範如何為影片加入超連結:

import aspose.slides as slides

with slides.Presentation() as presentation:
    slide = presentation.slides[0]

    with open("video.avi", "rb") as video_stream:
        video_data = video_stream.read()
        video = presentation.videos.add_video(video_data)
        
    video_frame = slide.shapes.add_video_frame(10, 10, 100, 100, video)

    video_frame.hyperlink_click = slides.Hyperlink("https://www.aspose.com/")
    video_frame.hyperlink_click.tooltip = "More than 70% of Fortune 100 companies trust Aspose APIs."

    presentation.save("output.pptx", slides.export.SaveFormat.PPTX)

使用超連結建立目錄

由於超連結可參照物件或位置,您可以利用它們建立目錄。

以下範例程式碼示範如何用超連結建立目錄:

import aspose.slides as slides

with slides.Presentation() as presentation:
    first_slide = presentation.slides[0]
    second_slide = presentation.slides.add_empty_slide(first_slide.layout_slide)

    content_table = first_slide.shapes.add_auto_shape(slides.ShapeType.RECTANGLE, 40, 40, 300, 100)
    content_table.fill_format.fill_type = slides.FillType.NO_FILL
    content_table.line_format.fill_format.fill_type = slides.FillType.NO_FILL
    content_table.text_frame.paragraphs.clear()

    paragraph = slides.Paragraph()
    paragraph.paragraph_format.default_portion_format.fill_format.fill_type = slides.FillType.SOLID
    paragraph.paragraph_format.default_portion_format.fill_format.solid_fill_color.color = draw.Color.black
    paragraph.text = "Title of slide 2 .......... "

    link_text_portion = slides.Portion()
    link_text_portion.text = "Page 2"
    link_text_portion.portion_format.hyperlink_manager.set_internal_hyperlink_click(second_slide)

    paragraph.portions.add(link_text_portion)
    content_table.text_frame.paragraphs.add(paragraph)

    presentation.save("link_to_slide.pptx", slides.export.SaveFormat.PPTX)

格式化超連結

本節說明如何在 Aspose.Slides 中格式化超連結的外觀。您將學會控制顏色與其他樣式選項,以在文字、圖形與圖片中保持超連結格式的一致性。

超連結顏色

使用 Hyperlink 類別的 color_source 屬性,您可以設定超連結的顏色並讀取顏色資訊。此功能於 PowerPoint 2019 引入,透過此屬性所做的變更不會套用至較早版本的 PowerPoint。

以下範例示範如何在同一投影片上加入不同顏色的超連結:

import aspose.slides as slides

with slides.Presentation() as presentation:
    slide = presentation.slides[0]

    shape1 = slide.shapes.add_auto_shape(slides.ShapeType.RECTANGLE, 100, 100, 600, 50, False)
    shape1.add_text_frame("This is a sample of a colored hyperlink.")

    text_portion1 = shape1.text_frame.paragraphs[0].portions[0]
    text_portion1.portion_format.hyperlink_click = slides.Hyperlink("https://www.aspose.com/")
    text_portion1.portion_format.hyperlink_click.color_source = slides.HyperlinkColorSource.PORTION_FORMAT
    text_portion1.portion_format.fill_format.fill_type = slides.FillType.SOLID
    text_portion1.portion_format.fill_format.solid_fill_color.color = draw.Color.red

    shape2 = slide.shapes.add_auto_shape(slides.ShapeType.RECTANGLE, 100, 200, 450, 50, False)
    shape2.add_text_frame("This is a sample of a regular hyperlink.")

    text_portion2 = shape2.text_frame.paragraphs[0].portions[0]
    text_portion2.portion_format.hyperlink_click = slides.Hyperlink("https://www.aspose.com/")

    presentation.save("hyperlinks.pptx", slides.export.SaveFormat.PPTX)

從簡報中移除超連結

本節說明在使用 Aspose.Slides 時,如何從簡報中移除超連結。您將學會在保留原始內容與格式的同時,清除文字、圖形與圖片的連結目標。

從文字中移除超連結

以下範例程式碼示範如何從投影片文字中移除超連結:

import aspose.slides as slides

with slides.Presentation("sample.pptx") as presentation:
    slide = presentation.slides[0]

    for shape in slide.shapes:
        if type(shape) is slides.AutoShape:
            for paragraph in shape.text_frame.paragraphs:
                for text_portion in paragraph.portions:
                    text_portion.portion_format.hyperlink_manager.remove_hyperlink_click()

    presentation.save("removed_hyperlinks.pptx", slides.export.SaveFormat.PPTX)

從圖形或框格中移除超連結

以下範例程式碼示範如何從投影片圖形中移除超連結:

import aspose.slides as slides

with slides.Presentation("sample.pptx") as presentation:
   slide = presentation.slides[0]

   for shape in slide.shapes:
       shape.hyperlink_manager.remove_hyperlink_click()

   presentation.save("removed_hyperlinks.pptx", slides.export.SaveFormat.PPTX)

可變超連結

Hyperlink 類別是可變的。使用此類別,您可以變更以下屬性之值:

以下程式碼片段示範如何為投影片新增超連結,然後編輯其工具提示文字:

import aspose.slides as slides

with slides.Presentation() as presentation:
    slide = presentation.slides[0]

    shape = slide.shapes.add_auto_shape(slides.ShapeType.RECTANGLE, 100, 100, 600, 50, False)
    shape.add_text_frame("Aspose: File Format APIs")

    text_portion = shape.text_frame.paragraphs[0].portions[0]
    text_portion.portion_format.hyperlink_click = slides.Hyperlink("https://www.aspose.com/")
    text_portion.portion_format.hyperlink_click.tooltip = "More than 70% of Fortune 100 companies trust Aspose APIs."

    presentation.save("output.pptx", slides.export.SaveFormat.PPTX)

IHyperlinkQueries 支援的屬性

您可以從簡報、投影片或包含超連結的文字框取得 HyperlinkQueries

HyperlinkQueries 類別支援以下方法:

常見問題

如何建立不僅指向投影片,而是指向「章節」或章節的第一張投影片的內部導覽?

PowerPoint 的章節是投影片的分組;導覽實際上會指向特定投影片。若要「導覽至章節」,通常會連結到該章節的第一張投影片。

我可以將超連結附加到母片元素,使其在所有投影片上皆可使用嗎?

可以。母片與版面配置元素支援超連結。此類連結會在子投影片上顯示,且在投影播放時可點擊。

將簡報匯出為 PDF、HTML、影像或影片時,超連結會被保留嗎?

PDFHTML中會保留連結。匯出為影像影片時,因為這些格式為點陣影格或影片,無法保留超連結的點擊功能。
