PdfTextFinder not working

[PaulDictu2]

Given the following method:

Code: Select all

private void AddHyperlinks(PdfDocument pdfDocument)
{
    var page = pdfDocument.GetSpecificPageByIndex(1);
    PdfTextFinder finder = new PdfTextFinder(page);
    finder.Options.Parameter = TextFindParameter.IgnoreCase;
    var pdfTextFragments = finder.FindAllText();
    foreach (var textFragment in pdfTextFragments)
    {
        foreach (var bounds in textFragment.Bounds)
        {
            PdfUriAnnotation url = new PdfUriAnnotation(bounds);
            url.Uri = "https://en.wikipedia.org/wiki/Climate_change";
            url.Border = new PdfAnnotationBorder(1f);
            url.Color = Color.Blue;
            clarificationPage.Annotations.Add(url);
        }
    }
}

Whenever I inspect the textFragment I get the following information

As you can see the Text parameter is filled with "\0\0\0" instead of text.
This also prevents me from using the finder.Find("text") because it won't match with the value in pdfTextFragment.text.
Hopefully you can help me.

The PDF isn't saved at this point in the code.
All the pages are created but it isn't saved to a disk.

Hello,

Thanks for your quick reply.
Sorry, based on the code you provided earlier, we are unable to further investigate your issue. You can provide us with your complete test code, or save your PDF to disk and send it to us. We need to know the content on the PDF page when you call the "FindAllText()" method.

I just emailed you the pdf.

Hello,

Thanks for your file.
May I ask which part of the content do you want to add hyperlinks to? Did "FindText ()" not match the corresponding content? Please tell us the keyword you are searched for.

The word(s) I am searching for are"Meer Info". I also tried "Meer" or "Info" but that also didn't result in any results.

 PdfTextFinder finder = new PdfTextFinder(pdfDocument.Pages[1]);
 finder.Options.Parameter = TextFindParameter.IgnoreCase;
 List<PdfTextFragment> pdfTextFragments = finder.Find("Meer Info");
 foreach (var textFragment in pdfTextFragments)
 {
     foreach (var bounds in textFragment.Bounds)
     {
         //...
