How to Rotate Text in Table Cell in Aspose.PDF .NET

Question

I'm using Aspose.PDF .NET 10.4 (latest as of this writing). I'm using their DOM api (not generator as that's deprecated).

How do I rotate text in a table cell 90 degrees counterclockwise?

Here's what I tried but the rotation on a rectangle had no affect.

Table table =  new Table();
table.DefaultCellBorder = new BorderInfo(BorderSide.All, 1f, Color.Black);
table.DefaultCellPadding = new MarginInfo(5, 5, 5, 5);

var headerRow = table.Rows.Add();
headerRow.FixedRowHeight = 100;
headerRow.DefaultCellTextState.HorizontalAlignment = HorizontalAlignment.Center;

for (int hc = 0; hc < 20; hc++)
{
    var cell = headerRow.Cells.Add();
    cell.BackgroundColor = Color.Red;
    cell.DefaultCellTextState.ForegroundColor = Color.White;
    cell.DefaultCellTextState.FontStyle = FontStyles.Bold;

    var h = new TextFragment("header-" + hc);
    h.Rectangle.Rotate(270); //this does nothing
    cell.Paragraphs.Add(h);
}

for (int r = 0; r < 15; r++)
{
    var row = table.Rows.Add();
    for (int c = 0; c < 20; c++)
    {
        row.Cells.Add(r + "-" + c);
    }
}

Document doc = new Document();
Page page = doc.Pages.Add();
page.Paragraphs.Add(table);
doc.Save("c:\temp\table.pdf");

Hi Dirq, I am a developer evangelist at Aspose. I have also managed to reproduce the above stated issue and as per my observations, the text inside table cell is not being rotated. For the sake of correction, I have logged it in our issue tracking system as PDFNEWNET-38829. We will further look into the details of this issue and will keep you posted on the status of correction. — codewarior, Jun 08 '15 at 12:13

How about something like:

row.Cells[0].VerticalTextRotationAngle = VerticalTextRotationType.AntiClockWise;

Hi Steve, Dirq is using new DOM approach of Aspose.Pdf namespace and the VerticalTextRotationAngle property is present in legacy Aspose.Pdf.Generator namespace. So I am afraid the above stated solution will not work with new DOM approach. – codewarior Jun 08 '15 at 12:11

Starting the recent release of Aspose.Pdf 17.5 it is possible to add rotated text fragments. Set angle value in degrees to TextState.Rotation property.

string myDir = @"D:\Temp\000\";
Aspose.Pdf.Table table = new Aspose.Pdf.Table();
table.DefaultCellBorder = new Aspose.Pdf.BorderInfo(Aspose.Pdf.BorderSide.All, 1f, Aspose.Pdf.Color.Black);
table.DefaultCellPadding = new Aspose.Pdf.MarginInfo(5, 5, 5, 5);

Row headerRow = table.Rows.Add();
headerRow.FixedRowHeight = 100;
headerRow.DefaultCellTextState.HorizontalAlignment = Aspose.Pdf.HorizontalAlignment.Center;

for (int hc = 0; hc < 4; hc++)
{
    Cell cell = headerRow.Cells.Add();
    cell.BackgroundColor = Aspose.Pdf.Color.Red;
    cell.DefaultCellTextState.ForegroundColor = Aspose.Pdf.Color.White;
    cell.DefaultCellTextState.FontStyle = FontStyles.Bold;

    TextFragment h = new TextFragment("header-" + hc);

    //Set rotation
    h.TextState.Rotation = 270;

    cell.Paragraphs.Add(h);
}

for (int r = 0; r < 15; r++)
{
    Row row = table.Rows.Add();
    for (int c = 0; c < 4; c++)
    {
        row.Cells.Add(r + "-" + c);
    }
}

Document doc = new Document();
Page page = doc.Pages.Add();
page.Paragraphs.Add(table);
doc.Save(myDir + "TextRotate_inCell_17_5.pdf");
