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)
Tip
您可能想參考管理使用 Python 的簡報中的 OLE。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?
