PdfTextFragment HighLight ist not transparent

[peterInStIngbert]

Hello
using PdfTextFragment.HighLight()

the highlighted area is not "transparently", the text it is completely covered.

Code: Select all

  private void button2_Click(object sender, EventArgs e)
  {
      PdfDocument pdfDoc = new PdfDocument(@"d:\tmp\test2.pdf");

      foreach (PdfPageBase page in pdfDoc.Pages)
      {

          PdfTextFinder finder = new PdfTextFinder(page);
          //finder.Options.Parameter = TextFindParameter.WholeWord;
          finder.Options.Parameter = TextFindParameter.IgnoreCase;

          List<PdfTextFragment> finds = finder.Find(this.textBox1.Text);

          foreach (PdfTextFragment fragment in finds)
          {
              // Highlight text
              fragment.HighLight(Color.LightYellow);
          }
      }

      this.pdfDocumentViewer1.LoadFromStream(pdfDoc.SaveToStream(FileFormat.PDF)[0]);
  }

Hello
Unfortunately, another quarter of a year has passed without the SPIREPDF-6689 issue being solved.
We often use the HighLight function in our software and the problem is very annoying.
Is there any timetable for this issue?

Sincerely
Peter

Thank you very much for the fix SPIREPDF-6689.
I tried it today after my vacation.
It works, but I do have one comment:
Unfortunately, the highlighted text is very blurry.
See my example.
