Text Background and Alignment

Hi,

I have same the problem in getting the text to change the text alignment to center and I am using Aspose.Pdf version 8.8.0.0.

Here is my code.

using (Aspose.Pdf.Document Doc = new Aspose.Pdf.Document(input))
            {
                foreach (Aspose.Pdf.Page page in Doc.Pages)
                {
                   
                        Aspose.Pdf.FloatingBox fb = new Aspose.Pdf.FloatingBox();
                        fb.Top = 520.0f;
                        //this was the version 1
                        //fb.Left = 331.0f;

                        fb.Left = -40.0f;
                        fb.Width = 510.23f;
                        fb.HorizontalAlignment = Aspose.Pdf.HorizontalAlignment.Center;
                        fb.VerticalAlignment = Aspose.Pdf.VerticalAlignment.Top;
                        fb.IsNeedRepeating = false;
                        //fb.IsExtraContentClip = true;
                        fb.IsKeptWithNext = false;

                        Aspose.Pdf.Table table = new Aspose.Pdf.Table();
                        //Set default cell border using BorderInfo object
                        //table.DefaultCellBorder = new Aspose.Pdf.BorderInfo(Aspose.Pdf.BorderSide.All, 0.1F);
                        table.Border = new Aspose.Pdf.BorderInfo(Aspose.Pdf.BorderSide.All, 1F, Aspose.Pdf.Color.Red);

                        //Set with column widths of the table
                        table.ColumnWidths = "100%";
                        Aspose.Pdf.Row row = new Row();
                        row.DefaultCellPadding = new MarginInfo(12,3,12,3);
                        Aspose.Pdf.Text.TextState textState = new Aspose.Pdf.Text.TextState();
                        textState.HorizontalAlignment = HorizontalAlignment.Center;
                        row.DefaultCellTextState = textState;

                        Aspose.Pdf.Cell cell = new Aspose.Pdf.Cell();
                        float fontSize = 12.0f;
                        cell.Alignment = HorizontalAlignment.Center;
                        HorizontalAlignment alignment = Aspose.Pdf.HorizontalAlignment.Center;
                        Aspose.Pdf.Text.TextFragment txtFragment = new Aspose.Pdf.Text.TextFragment();
                        txtFragment.TextState.HorizontalAlignment = alignment;

                        // Add a text segment to text together
                        Aspose.Pdf.Text.TextSegment segmentText = new Aspose.Pdf.Text.TextSegment();
                        Aspose.Pdf.Text.Font font = Aspose.Pdf.Text.FontRepository.FindFont("Arial");
                        font.IsEmbedded = true;
                        segmentText.TextState.Font = font;
                        segmentText.TextState.FontSize = fontSize;
                        segmentText.TextState.FontStyle = Aspose.Pdf.Text.FontStyles.Regular;
                        segmentText.TextState.ForegroundColor = Aspose.Pdf.Color.Red;
                        segmentText.TextState.HorizontalAlignment = alignment;
                        segmentText.Text = "The Govt estimates that the Federal carbon tax and green energy schemes add about $100 a year to a typical 6.5MWh household bill.";

                        txtFragment.Segments.Add(segmentText);
                        cell.Paragraphs.Add(txtFragment);

                        row.Cells.Add(cell);
                        table.Rows.Add(row);

                        fb.Paragraphs.Add(table);
                        page.Paragraphs.Add(fb);
                }

                Doc.Save(stream);v
