In general , stay Word Adding a text watermark in only supports adding a text watermark , But in a complex office environment , Due to the design requirements of different documents , Need to be in Word Add tile watermark effect to the document , That is, the watermark text in the document exists in the form of multi line and multi column distribution . This paper will introduce how to realize the watermark effect , Here are the detailed steps and methods .

dll quote

adopt NuGet introduce dll（2 Methods ） Methods

1. Can be in Visual Studio Open in “ Solution explorer ”, Right click “ quote ”,“ management NuGet package ”, And then the search “Free Spire.Doc”, Click on “ install ”. Wait for the program installation to complete .

2. Copy the following to PM Console installation ：

       
       Install-PackageFreeSpire.Doc -Version 10.2
      
1.

Manually add dll Quoted method

Can be manually Download package To local , Then decompress , find BIN Under folder Spire.Doc.dll. And then in Visual Studio Open in “ Solution explorer ”, Right click “ quote ”,“ Add reference ”, The local path BIN Under folder dll Add a reference to the program .

Add multi line and multi column text watermark

stay Word When adding multi line text watermark in , The way to achieve this is to add shape WordArt in the header , The watermark effect of multi line text is simulated by copying the shape many times . The following are the main code steps to realize watermark addition ：

establish Document Class object , And call Document.LoadFromFile(string fileName) Method loading Word file .
establish ShapeObject Class , And pass ShapeObject.Width、ShapeObject.Height、ShapeObject.VerticalPosition、ShapeObject.Rotation、ShapeObject.WordArt.Text、ShapeObject.WordArt.FontFamily、ShapeObject.FillColor And other properties to set the shape size 、 Location 、 Rotation Angle 、 Watermark text 、 Font and color, etc .
for Loop through all Section, adopt Section.HeadersFooters.Header Property to get the header , And HeaderFooter.AddParagraph() Method to add a paragraph to the header .
adopt for Cycle to ShapeObject.Clone() Method copies the shape multiple times , And pass ShapeObject.VerticalPosition and ShapeObject.HorizontalPosition Property to set the shape position arrangement .
call Paragraph.ChildObjects.Add(IDocumentObject entity) Method to add a shape to the header paragraph .
Last , adopt Document.SaveToFile(string fileName, FileFormat fileFormat) Method to save the document to the specified path .
