Hi,

You should use PdfTextObject.Font property to get the font parameters.

To find the match between selected text and PdfTextObject you can find the intersection between bounded rectangles of the selection and the bounded rectangle of the each PdfTextObject on the pages where that selection is located.

I wrote the following:


Code:
HighlightInfo hi = new HighlightInfo();
hi.CharIndex = pdfViewerOriginal.SelectInfo.StartIndex;
hi.CharsCount = pdfViewerOriginal.SelectedText.Length;
var rects = new List<System.Drawing.Rectangle>();
for (int page = pdfViewerOriginal.SelectInfo.StartPage; page <= pdfViewerOriginal.SelectInfo.EndPage; page++)
{
     rects.AddRange(pdfViewerOriginal.GetHighlightedRects(page, hi));
}
for(int i = 0; i < rects.Count; i++)
{
     foreach(PdfTextObject pto in allTextObjOriginal)
     {
     var r = pto.BoundingBox;
     if (rects[i].IntersectsWith(new System.Drawing.Rectangle((int)r.left, (int)r.top, (int)r.Width, (int)r.Height)))
     {
           fulltext += pto.TextAnsi;
           break;
     }
}



But it seems GetHighlightedRects() return Rects that change location according to the viewer's zoom.

I want to get every PdfTextObject of my selected text.



Kind Regars,

You should convert the coordinates of bounding box of text object to the control coordinate system

Or, vise versus, convert the coordinates of selection to the page coordinate system
