Hi Oren,

Thanks for your inquiry. You can iterate through the LinkAnnotaions and update the different properties as per your need. You can set an empty URI to disable the LinkAnnotaiton.

Document doc = new Document("input.pdf");

// Get the first link annotation from the first page of the document
LinkAnnotation linkAnnot = (LinkAnnotation)doc.Pages[1].Annotations[1];

if (linkAnnot.Action is GoToURIAction)
{
    // Modify the link: change link URI
    GoToURIAction goToAction = (GoToURIAction)linkAnnot.Action;

    // Specify the URI for the link object
    goToAction.URI = "";

    // Save the document with the updated link

    // Search the text under the annotation
    TextFragmentAbsorber ta = new TextFragmentAbsorber();
    Aspose.Pdf.Rectangle rect = linkAnnot.Rect;
    rect.LLX -= 10;
    rect.LLY -= 10;
    rect.URX += 10;
    rect.URY += 10;
    ta.TextSearchOptions = new TextSearchOptions(rect);
    ta.Visit(doc.Pages[1]);

    // Change color and text.
    foreach (TextFragment tf in ta.TextFragments)
    {
        tf.TextState.ForegroundColor = Aspose.Pdf.Color.Red;
        tf.Text = "Click Here";
    }
}

doc.Save("output.pdf");

Please contact us for any further assistance.

Hi
Thank you very much for the example.
How can I disable links that are generated from a text such as:
http://edition.cnn.com . If the text has a pattern of link (e.g. http, www…) the PDF Acrobat link the text.

Thanks

After initial investigation we have logged a ticket PDFNEWNET-38688 in our issue tracking system for further investigation and resolution.

Hi Camille,

Thanks for your inquiry. Please note we cannot delete hyperlinks from such text, because there are no any links. Viewer (Adobe or Foxit) converts a text that matches to a link and e-mail format and makes it active automatically. However as a workaround we can override the default link by our LinkAnnotation object configured with empty GoToAction. Please try following sample code snippet, hopefully it will help you to accomplish the task.

// load the PDF file
Document doc = new Document(myDir+"Hyperlink.pdf");

//create TextAbsorber object to find
//all the phrases matching the regular expression for hyperlink of e-mail
TextFragmentAbsorber textFragmentAbsorber = new TextFragmentAbsorber("(\\b(https?|ftp|file)://[-a-zA-Z0-9+&@#/%?=~_|!:,.;]*[-a-zA-Z0-9+&@#/%=~_|])|((([a-zA-Z]|[0-9])|([-]|[_]|[.]))+[@](([a-zA-Z0-9])|([-])){2,63}[.](([a-zA-Z0-9]){2,63})+$)");

//set text search option to specify
//regular expression usage
TextSearchOptions textSearchOptions = new TextSearchOptions(true);
textFragmentAbsorber.TextSearchOptions=textSearchOptions;

int pageNum = 1;
//accept the absorber for all the pages
Aspose.Pdf.Page page =
  doc.Pages[pageNum];
page.Accept(textFragmentAbsorber);

//get the extracted text fragments
TextFragmentCollection textFragmentCollection =
  textFragmentAbsorber.TextFragments;

//loop through the fragments
foreach (TextFragment textFragment in textFragmentCollection)
{
    LinkAnnotation linkAnnot = new LinkAnnotation(page, textFragment.Rectangle);
    linkAnnot.Border=new Border(linkAnnot);
    linkAnnot.Border.Width=0;
    page.Annotations.Add(linkAnnot);
}

doc.Save(myDir+"HyperlinkRemoved.pdf");

Best Regards,
