Hi,


I try to add a Watermarkt in a WORD document but having an issue. It works perfectly if i don’t edit the document. But if i edit it using WORD(i.e. adding some text) and then add the Watermarkt, the file is corrupted. Can you help me please ?

Here the code i use :

private void addWatermark()
{
using (FileStream fileStream = new FileStream(@“C:\Users\Kevin\Documents\input.docm”, FileMode.Open, FileAccess.ReadWrite))
{
insertWatermarkText(fileStream, “WATERMARKT”);
}

}
private void insertWatermarkText(Stream fileStream, string watermarkText)
{
Aspose.Words.Document doc = new Aspose.Words.Document(fileStream);

// Create a watermark shape. This will be a WordArt shape.
// You are free to try other shape types as watermarks.
Aspose.Words.Drawing.Shape watermark = new Aspose.Words.Drawing.Shape(doc, Aspose.Words.Drawing.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 = System.Drawing.Color.Gray; // Try LightGray to get more Word-style watermark
watermark.StrokeColor = System.Drawing.Color.Gray; // Try LightGray to get more Word-style watermark

// Place the watermark in the page center.
watermark.RelativeHorizontalPosition = Aspose.Words.Drawing.RelativeHorizontalPosition.Page;
watermark.RelativeVerticalPosition = Aspose.Words.Drawing.RelativeVerticalPosition.Page;
watermark.WrapType = Aspose.Words.Drawing.WrapType.None;
watermark.VerticalAlignment = Aspose.Words.Drawing.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);
}

doc.Save(fileStream, Aspose.Words.SaveFormat.Docm);
fileStream.Seek(0, SeekOrigin.Begin);
}
private void insertWatermarkIntoHeader(Paragraph watermarkPara, Section sect, HeaderFooterType headerType)
{
Aspose.Words.HeaderFooter header = sect.HeadersFooters[headerType];

if (header == null)
{
// There is no header of the specified type in the current section, create it.
header = new Aspose.Words.HeaderFooter(sect.Document, headerType);
sect.HeadersFooters.Add(header);
}

// Insert a clone of the watermark into the header.
header.AppendChild(watermarkPara.Clone(true));
}

Thanks!

Hi there,


Just to clarify the fix for this issue, it was closed as not a bug. You are saving the modified document back to the original stream which results in a corrupt document.

You need to use code like the following, however it is recommended to save to a completely separate stream anyway.

using (FileStream fileStream = new FileStream(@“C:\Temp\any.docx”, FileMode.Open, FileAccess.ReadWrite))

{

Document doc = new Document(fileStream);

<span style="line-height: 1.3em;">fileStream.Position = 0;</span><span class="code-comment" style="color: rgb(128, 128, 128);">


    
    doc.Save(fileStream, SaveFormat.Docx);
}


Thanks,
