Rotate Text inside Table Cell

Table is one of the widely used element inside PDF document to represent data and sometimes we have a requirement to rotate the text inside the table cell. The following code snippet shows the steps to rotate text with 90 degrees and render it in table cell.


// create Document instance
Document doc = new Document();
// add page to pages collection of Document instance
Page pg = doc.Pages.Add();
// create table instance
Table tab = new Table();
tab.DefaultCellTextState.FontSize = 7;
tab.DefaultCellPadding = new MarginInfo(7, 7, 7, 7);
tab.DefaultCellBorder = new BorderInfo(BorderSide.All, 0.1f);

Aspose.Pdf.Text.TextFragment verticalTextFragment = new Aspose.Pdf.Text.TextFragment("Gradient");
verticalTextFragment.TextState.Rotation = 90;
tab.ColumnWidths = (verticalTextFragment.Rectangle.Width + 5).ToString(System.Globalization.CultureInfo.InvariantCulture) + " " + (verticalTextFragment.Rectangle.Width + 5).ToString(System.Globalization.CultureInfo.InvariantCulture);
Row r1 = tab.Rows.Add();
Cell c1 = r1.Cells.Add();
c1.RowSpan = 3;
r1.Cells.Add("A");

Row r2 = tab.Rows.Add();
r2.Cells.Add("B");

Row r3 = tab.Rows.Add();
r3.Cells.Add("C");
// add Vertical Text to paragraphs collection of Cell instance
c1.Paragraphs.Add(verticalTextFragment);
// add table to paragraphs collection of Page instance
pg.Paragraphs.Add(tab);

Table tab1 = new Table();
tab1.Margin.Top = 50;
tab1.DefaultCellTextState.FontSize = 7;
tab1.DefaultCellPadding = new MarginInfo(7, 7, 7, 7);
tab1.DefaultCellBorder = new BorderInfo(BorderSide.All, 0.1f);

Aspose.Pdf.Text.TextFragment verticalTextFragment1 = new Aspose.Pdf.Text.TextFragment("Gradient");
// set rotation angle for Text as 90 degrees
verticalTextFragment.TextState.Rotation = 90;
//After rotation height of the text will be width of particular column. 
tab1.ColumnWidths = (verticalTextFragment.Rectangle.Height + 5).ToString(System.Globalization.CultureInfo.InvariantCulture) + " " + (verticalTextFragment.Rectangle.Width + 5).ToString(System.Globalization.CultureInfo.InvariantCulture);
Row r11 = tab1.Rows.Add();
Cell c11 = r11.Cells.Add();
c11.RowSpan = 3;
r11.Cells.Add("A");

Row r22 = tab1.Rows.Add();
r22.Cells.Add("B");

Row r33 = tab1.Rows.Add();
r33.Cells.Add("C");
// add vertical text with 90 degress to paragraphs collection of Cell instance
c11.Paragraphs.Add(verticalTextFragment);
// add second table to paragraphs collection of Page instance
pg.Paragraphs.Add(tab1);
// save the resultant PDF document
doc.Save(@"c:/pdftest/RotateText.pdf");
