                PdfDocument pdfDoc = PdfDocument.Merge(null, document) as PdfDocument;
                //Gets the first page from the document
                float width = pdfDoc.Pages[0].Size.Width;
                float height = pdfDoc.Pages[0].Size.Height;
                if (pdfDoc.Pages[0].Rotation == PdfPageRotateAngle.RotateAngle90 ||
                    pdfDoc.Pages[0].Rotation == PdfPageRotateAngle.RotateAngle270)
                    width = pdfDoc.Pages[0].Size.Height;
                    height = pdfDoc.Pages[0].Size.Width;

                if (width > height)
                    pdfDoc.Sections[0].PageSettings.Orientation = PdfPageOrientation.Portrait;
                    pdfDoc.Sections[0].PageSettings.Orientation = PdfPageOrientation.Landscape;
                    pdfDoc.Sections[0].PageSettings.Size = new SizeF(width, height);

                //Add a list to maintain extracted text information
                List<TextData> extractedText = new List<TextData>();
                //Extract text from first page
                pdfDoc.Sections[0].Pages[0].ExtractText(out extractedText);
                //for (var yu = 0; yu < arrvalues_smipp.Length; yu++)
                foreach (TextData textData in extractedText)
                    if (textData.Text == "F261")
                        PdfGraphics graphics = pdfDoc.Pages[0].Graphics;
                        Font font = new Font("Calibri", 10, FontStyle.Bold);
                        PdfFont pdfFont = new PdfTrueTypeFont(font, false);
                        PdfSolidBrush brush = new PdfSolidBrush(Color.DarkGreen);
                        PdfPen pen = new PdfPen(PdfBrushes.DarkMagenta, 5f);
                        float x_coordiante = textData.Bounds.Location.X - 3;
                        float y_coordinate = textData.Bounds.Location.Y - 10;
                        float width1 = textData.Bounds.Size.Width;
                        float height1 = textData.Bounds.Size.Height;
                        RectangleF rectangle = new RectangleF(x_coordiante, y_coordinate, width1, height1);
                        PdfTextMarkupAnnotation textmarkup = new PdfTextMarkupAnnotation("", "", textData.Text, new PointF(x_coordiante, y_coordinate), pdfFont);
                        textmarkup.TextMarkupColor = new PdfColor(Color.LightPink);
                        textmarkup.TextMarkupAnnotationType = PdfTextMarkupAnnotationType.Highlight;
                        textmarkup.Rotate = PdfAnnotationRotateAngle.RotateAngle180;

Hi Yogesh, 

Thank you for contacting Syncfusion support.  

We have checked with the issue which you have mentioned with the provided code snippet, but in our end the text is highlighted as horizontal only. So we suspect that this to be a document specific issue, so could you please share the input PDF file which you have used in your end. It will helpful for us to provide the precise solution on this.
