Manage Hyperlinks

A hyperlink is a reference to an object or data or a place in something. These are common hyperlinks in PowerPoint Presentations:

Links to websites inside texts, shapes, or media
Links to slides

Aspose.Slides for Android via Java allows you to perform many tasks involving hyperlinks in presentations.

Adding URL Hyperlinks

Adding URL Hyperlinks to Texts

This Java code shows you how to add a website hyperlink to a text:

Presentation presentation = new Presentation();
try {
	IAutoShape shape1 = presentation.getSlides().get_Item(0).getShapes().addAutoShape(ShapeType.Rectangle, 100, 100, 600, 50, false);
	shape1.addTextFrame("Aspose: File Format APIs");
	
	IPortionFormat portionFormat = shape1.getTextFrame().getParagraphs().get_Item(0).getPortions().get_Item(0).getPortionFormat(); 
	portionFormat.setHyperlinkClick(new Hyperlink("https://www.aspose.com/"));
	portionFormat.getHyperlinkClick().setTooltip("More than 70% Fortune 100 companies trust Aspose APIs");
	portionFormat.setFontHeight(32);

	presentation.save("presentation-out.pptx", SaveFormat.Pptx);
} finally {
	if (presentation != null) presentation.dispose();
}

Adding URL Hyperlinks to Shapes or Frames

This sample code in Java shows you how to add a website hyperlink to a shape:

Presentation pres = new Presentation();
try {
	IShape shape = pres.getSlides().get_Item(0).getShapes().addAutoShape(ShapeType.Rectangle, 100, 100, 600, 50);

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

	pres.save("pres-out.pptx", SaveFormat.Pptx);
} finally {
	if (pres != null) pres.dispose();
}

Adding URL Hyperlinks to Media

Aspose.Slides allows you to add hyperlinks to images, audio, and video files.

This sample code shows you how to add a hyperlink to an image:

Presentation pres = new Presentation();
try {
	// Adds image to presentation
    IPPImage picture;
    IImage image = Images.fromFile("image.png");
    try {
    picture = pres.getImages().addImage(picture);
    } finally {
          if (image != null) image.dispose();
    }
	// Creates picture frame on slide 1 based on previously added image
	IPictureFrame pictureFrame = pres.getSlides().get_Item(0).getShapes().addPictureFrame(ShapeType.Rectangle, 10, 10, 100, 100, picture);

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

	pres.save("pres-out.pptx", SaveFormat.Pptx);
} catch(IOException e) {
} finally {
	if (pres != null) pres.dispose();
}

This sample code shows you how to add a hyperlink to an audio file:

Presentation pres = new Presentation();
try {
	IAudio audio = pres.getAudios().addAudio(Files.readAllBytes(Paths.get("audio.mp3")));
	IAudioFrame audioFrame = pres.getSlides().get_Item(0).getShapes().addAudioFrameEmbedded(10, 10, 100, 100, audio);

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

	pres.save("pres-out.pptx", SaveFormat.Pptx);
} catch(IOException e) {
} finally {
	if (pres != null) pres.dispose();
}

This sample code shows you how to add a hyperlink to a video:

Presentation pres = new Presentation();
try {
	IVideo video = pres.getVideos().addVideo(Files.readAllBytes(Paths.get("video.avi")));
	IVideoFrame videoFrame = pres.getSlides().get_Item(0).getShapes().addVideoFrame(10, 10, 100, 100, video);

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

	pres.save("pres-out.pptx", SaveFormat.Pptx);
} catch(IOException e) {
} finally {
	if (pres != null) pres.dispose();
}

Using Hyperlinks to Create Table of Contents

Since hyperlinks allow you to add references to objects or places, you can use them to create a table of contents.

This sample code shows you how to create a table of contents with hyperlinks:

Presentation pres = new Presentation();
try {
	ISlide firstSlide = pres.getSlides().get_Item(0);
	ISlide secondSlide = pres.getSlides().addEmptySlide(firstSlide.getLayoutSlide());

	IAutoShape contentTable = firstSlide.getShapes().addAutoShape(ShapeType.Rectangle, 40, 40, 300, 100);
	contentTable.getFillFormat().setFillType(FillType.NoFill);
	contentTable.getLineFormat().getFillFormat().setFillType(FillType.NoFill);
	contentTable.getTextFrame().getParagraphs().clear();

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

	Portion linkPortion = new Portion();
	linkPortion.setText("Page 2");
	linkPortion.getPortionFormat().getHyperlinkManager().setInternalHyperlinkClick(secondSlide);

	paragraph.getPortions().add(linkPortion);
	contentTable.getTextFrame().getParagraphs().add(paragraph);

	pres.save("link_to_slide.pptx", SaveFormat.Pptx);
} finally {
	if (pres != null) pres.dispose();
}

Formatting Hyperlinks

Color

With the ColorSource property in the IHyperlink interface, you can set the color for hyperlinks and also get the color information from hyperlinks. The feature was first introduced in PowerPoint 2019, so changes involving the property do not apply to older PowerPoint versions.

This sample code demonstrates an operation where hyperlinks with different colors got added to the same slide:

Presentation pres = new Presentation();
try {
	IAutoShape shape1 = pres.getSlides().get_Item(0).getShapes().addAutoShape(ShapeType.Rectangle, 100, 100, 450, 50, false);
	shape1.addTextFrame("This is a sample of colored hyperlink.");
	IPortionFormat portionFormat = shape1.getTextFrame().getParagraphs().get_Item(0).getPortions().get_Item(0).getPortionFormat();
	portionFormat.setHyperlinkClick(new Hyperlink("https://www.aspose.com/"));
	portionFormat.getHyperlinkClick().setColorSource(HyperlinkColorSource.PortionFormat);
	portionFormat.getFillFormat().setFillType(FillType.Solid);
	portionFormat.getFillFormat().getSolidFillColor().setColor(Color.RED);

	IAutoShape shape2 = pres.getSlides().get_Item(0).getShapes().addAutoShape(ShapeType.Rectangle, 100, 200, 450, 50, false);
	shape2.addTextFrame("This is a sample of usual hyperlink.");
	shape2.getTextFrame().getParagraphs().get_Item(0).getPortions().get_Item(0).getPortionFormat().setHyperlinkClick(new Hyperlink("https://www.aspose.com/"));

	pres.save("presentation-out-hyperlink.pptx", SaveFormat.Pptx);
} finally {
	if (pres != null) pres.dispose();
}

Removing Hyperlinks in Presentations

Removing Hyperlinks from Texts

This Java code shows you how to remove the hyperlink from a text in a presentation slide:

Presentation pres = new Presentation();
try {
	ISlide slide = pres.getSlides().get_Item(0);
	for (IShape shape : slide.getShapes())
	{
		IAutoShape autoShape = (IAutoShape)shape;
		if (autoShape != null)
		{
			for (IParagraph paragraph : autoShape.getTextFrame().getParagraphs())
			{
				for (IPortion portion : paragraph.getPortions())
				{
					portion.getPortionFormat().getHyperlinkManager().removeHyperlinkClick();
				}
			}
		}
	}

	pres.save("pres-removed-hyperlinks.pptx", SaveFormat.Pptx);
} finally {
	if (pres != null) pres.dispose();
}

Removing Hyperlinks from Shapes or Frames

This Java code shows you how to remove the hyperlink from a shape in a presentation slide:

Presentation pres = new Presentation();
try {
	ISlide slide = pres.getSlides().get_Item(0);
	for (IShape shape : slide.getShapes())
	{
		shape.getHyperlinkManager().removeHyperlinkClick();
	}
	pres.save("pres-removed-hyperlinks.pptx", SaveFormat.Pptx);
} finally {
	if (pres != null) pres.dispose();
}

Mutable Hyperlink

The Hyperlink class is mutable. With this class, you can change the values for these properties:

The code snippet shows you how to add a hyperlink to a slide and edit its tooltip later:

Presentation pres = new Presentation();
try {
	IAutoShape shape1 = pres.getSlides().get_Item(0).getShapes().addAutoShape(ShapeType.Rectangle, 100, 100, 600, 50, false);
	shape1.addTextFrame("Aspose: File Format APIs");

	IPortionFormat portionFormat = shape1.getTextFrame().getParagraphs().get_Item(0).getPortions().get_Item(0).getPortionFormat(); 
	portionFormat.setHyperlinkClick(new Hyperlink("https://www.aspose.com/"));
	portionFormat.getHyperlinkClick().setTooltip("More than 70% Fortune 100 companies trust Aspose APIs");
	portionFormat.setFontHeight(32);

	pres.save("presentation-out.pptx", SaveFormat.Pptx);
} finally {
	if (pres != null) pres.dispose();
}
