I don't quite understand there you have a problems.
Are you use PdfToolStripSearch or implements the search routine yourself via PdfSearch Class?

If I understand you correctly, in order to determine whether the text on the page is visible, you can get the bounding boxes of each found characters in the page's coordinates.
Code:

var textInfo = Document.Pages[pageIndex].Text.GetTextInfo(e.CharIndex, e.CharsCount);


Next you can convert them to the control's coordinate system.
Code:

  var pt1 = pdfViewer1.PageToDevice(rc.left, rc.top, pageIndex);
  var pt2 = pdfViewer1.PageToDevice(rc.right, rc.bottom, pageIndex);


And then compare these coordinates with PdfViewer's ClientArea.

Hi,

I used both controls, the WPF and the WinForms control (WinForms preferred).
My problem is the following:
First, the user zooms into a page inside a PDF document.
Then, he'd like to search for a specific text.

While both functions (Zoom and Highlighting) works perfectly when the whole page is shown,
there is a problem to get Highlighted text into the visible area of a zoomed page.
Is there an explanation how to accomplish that?

Currently, I have two dlls referenced in my project.
PataGames.Pdf.Winforms and
PataGames.Pdf.

Many thanks for your help
