With below code I am able to replace to uri address of links but don’t know how to replace link label.

Document document = new Document("E:\\files\\Testing_hyperlink.pdf");

for (Page page : document.getPages()) {

		for (Object object : page.getAnnotations()) {
					
		Annotation annotation = (Annotation) object;
					
		if(annotation.getAnnotationType() == AnnotationType.Link) {
						
			LinkAnnotation linkAnnotation = (LinkAnnotation) annotation;
						
			if(linkAnnotation.getAction() instanceof GoToURIAction) {
							
				GoToURIAction gotoAction = (GoToURIAction) linkAnnotation.getAction();
							
				System.out.println(gotoAction.getURI());
							
				gotoAction.setURI("www.gmail.com");
			}
						
		}
					
	}
		
}
document.save("E:\\files\\Testing_hyperlink1.pdf");

        if(annotation.getAnnotationType() == AnnotationType.Link) 
        {
            LinkAnnotation linkAnnotation = (LinkAnnotation) annotation;
            // get hyperlink text
            TextFragmentAbsorber absorber = new TextFragmentAbsorber();
            absorber.getTextSearchOptions().setRectangle(linkAnnotation.getRect());
            absorber.visit(page);
            for (TextFragment tf : absorber.getTextFragments())
            {
                System.out.println(tf.getText());
                tf.setText("MODIFIED TEXT");
                linkAnnotation.setRect(tf.getRectangle());
            }
            if(linkAnnotation.getAction() instanceof GoToURIAction) 
            {
                GoToURIAction gotoAction = (GoToURIAction) linkAnnotation.getAction();
                System.out.println(gotoAction.getURI());
                gotoAction.setURI("www.gmail.com");
            }
        }
    }

Thanks for your support.
Link Labels are getting replaced now but there are multiple labels created for single link and they are overlapping each other. Is there a way to get entire link label in single TextFragment or any other approach to solve this?

I am attaching my source and destination pdf files named as Testing_hyperlink.pdf and Testing_hyperlink1.pdf respectively.

Testing_hyperlink1.pdf (191.2 KB)

Thank you for being patient.

We have investigated and resolved the ticket reported by you and would like to request you to use below code snippet in your environment and then share your kind feedback with us.

Document document = new Document(dataDir + "Hyperlink_17.4.pdf");
    for (Page page : document.getPages()) {
        for (Object object : page.getAnnotations()) {
            Annotation annotation = (Annotation) object;
            if (annotation.getAnnotationType() == AnnotationType.Link) {
                LinkAnnotation linkAnnotation = (LinkAnnotation) annotation;
                TextFragmentAbsorber absorber = new TextFragmentAbsorber();

                TextEditOptions editOptions = new TextEditOptions(TextEditOptions.LanguageTransformation.Default);
                editOptions.setToAttemptGetUnderlineFromSource(true);

                TextSearchOptions textSearchOptions = new TextSearchOptions(true);
                absorber.setTextSearchOptions(textSearchOptions);
                absorber.setTextEditOptions(editOptions);

                absorber.getTextSearchOptions().setRectangle(linkAnnotation.getRect());
                absorber.visit(page);
                TextFragment tf = absorber.getTextFragments().get_Item(1);
                tf.setText("MODIFIED TEXT");
                linkAnnotation.setRect(tf.getRectangle());

                if (linkAnnotation.getAction() instanceof GoToURIAction) {
                    GoToURIAction gotoAction = (GoToURIAction) linkAnnotation.getAction();
                    gotoAction.setURI("www.gmail.com");
                }
            }
        }
    }
    document.save(dataDir + "output_1.pdf");

It replaces the label of hyperlink as per your requirements. We have attached the generated file for your kind reference output_1.pdf. Please feel free to contact us if you need any further assistance.
