Centering text in multi-line watermark

Aspose.Words Product Family
1

I am using your recommended code for adding watermarks to a document via a TextPlainText shape inserted to the headers.
My TextPath.Text value is “2 LINE\r\nWATERMARK” and the TextPath.TextPathAlignment is Center. I’m getting two lines of text, but the text is left justified…
2 LINE
WATERMARK
rather than…
2 LINE
WATERMARK
When the shape is rotated, the lines retain this left alignment, the W remains below the 2.
In Microsoft Word, the WordArt object supports multiple line text and the text on each line is centered. Is there a way to do this in Aspose.Words? I am currently evaluating version 11.7.

Hi David,

Thanks for your query. Please use the following code snippet with Aspose.Words for .NET 11.7.0. I have attached the output Docx file with this post. The “2 LINE\r\nWATERMARK” is center aligned in output document. Please let us know if you have any more queries.

Document doc = new Document();
InsertWatermarkText(doc, "2 LINE\r\nWATERMARK");
doc.Save(MyDir + "AsposeOut.docx");
///
/// Inserts a watermark into a document.
///
/// The input document.
/// Text of the watermark.
private static void InsertWatermarkText(Document doc, string watermarkText)
{
    // Create a watermark shape. This will be a WordArt shape.
    // You are free to try other shape types as watermarks.
    Shape watermark = new Shape(doc, ShapeType.TextPlainText);
    // Set up the text of the watermark.
    watermark.TextPath.Text = watermarkText;
    watermark.TextPath.FontFamily = "Arial";
    watermark.Width = 500;
    watermark.Height = 100;
    // Text will be directed from the bottom-left to the top-right corner.
    watermark.Rotation = -40;
    // Remove the following two lines if you need a solid black text.
    watermark.Fill.Color = Color.Gray; // Try LightGray to get more Word-style watermark
    watermark.StrokeColor = Color.Gray; // Try LightGray to get more Word-style watermark
    // Place the watermark in the page center.
    watermark.RelativeHorizontalPosition = RelativeHorizontalPosition.Page;
    watermark.RelativeVerticalPosition = RelativeVerticalPosition.Page;
    watermark.WrapType = WrapType.None;
    watermark.VerticalAlignment = VerticalAlignment.Center;
    watermark.HorizontalAlignment = Aspose.Words.Drawing.HorizontalAlignment.Center;
    // Create a new paragraph and append the watermark to this paragraph.
    Paragraph watermarkPara = new Paragraph(doc);
    watermarkPara.AppendChild(watermark);
    // Insert the watermark into all headers of each document section.
    foreach(Section sect in doc.Sections)
    {
        // There could be up to three different headers in each section, since we want
        // the watermark to appear on all pages, insert into all headers.
        InsertWatermarkIntoHeader(watermarkPara, sect, HeaderFooterType.HeaderPrimary);
        InsertWatermarkIntoHeader(watermarkPara, sect, HeaderFooterType.HeaderFirst);
        InsertWatermarkIntoHeader(watermarkPara, sect, HeaderFooterType.HeaderEven);
    }
}\ == private static void InsertWatermarkIntoHeader(Paragraph watermarkPara, Section sect, HeaderFooterType headerType)
{
    HeaderFooter header = sect.HeadersFooters[headerType];
    if (header == null)
    {
        // There is no header of the specified type in the current section, create it.
        header = new HeaderFooter(sect.Document, headerType);
        sect.HeadersFooters.Add(header);
    }
    // Insert a clone of the watermark into the header.
    header.AppendChild(watermarkPara.Clone(true));
}

That was the code block I was using (plus a few changes for color). While this produces the center aligned watermark in a docx file, saving the document to a PDF file or sending it to a printer yields a left-aligned watermark. Please see the attached files showing the different output in DOCX and PDF.
