When setting the watermark in Word, you can use the preset text or custom text to set the watermark effect, but usually when adding the watermark effect, it will All pages are set to a uniform effect. If you need to set a different watermark effect for each page or a certain page, you can refer to the method in this article. Below, we will take the C# code as an example to introduce in detail how to set different text watermark effects for each page of Word.

Methodology

Before adding a text watermark to each page of Word, you first need to add a text watermark to the Word documentEvery pageAfter the last character of the textInsert a "continuous" section break , then Add a WordArt shape to the header paragraph of each section, and set the shape size, alignment, etc. Finally save the document.

dll reference

Method 1

Introduce Spire.Doc into the program .dll file; download Spire.Doc for .NET locally, unzip it, and find Spire.Doc.dll under the BIN folder. Then open the "Solution Explorer" in Visual Studio, right-click "References", "Add Reference", and add references to the dll files in the BIN folder of the local path to the program.

Method 2

Install via NuGet. There are two ways to install:

1. Can be used in Visual Studio Open the "Solution Explorer", right-click "References", "Manage NuGet Packages", then search for "Spire.Doc", click "Install". Wait for the program installation to complete.

2. Copy the following into PM console installation.

Install-Package Spire.Doc -Version 10.1.14

Code example

When adding a text watermark to each page, you can refer to the following steps:

• CreateDocumentClass object, and passed LoadFromFile(string fileName) method to load a Word document.
• Pass< span style="color: #000000; --tt-darkmode-color: #A3A3A3;">Document.Sections[] The property gets the specified section.
• Pass< span style="color: #000000; --tt-darkmode-color: #A3A3A3;">HeadersFooters.HeaderProperty to get header,HeaderFooter.AddParagraph() method to add a paragraph to the header.
• Create< span style="color: #000000; --tt-darkmode-color: #A3A3A3;">ShapeObject class object, and pass in parameters to set the shape type to TextPlainText type of WordArt. And call the method to set the WordArt style, such as the height, width, rotation, color, alignment, etc. of the WordArt.
• use< span style="color: #000000; --tt-darkmode-color: #A3A3A3;">DocumentObjectCollection.Add(IDocumentObject) method adds WordArt to a paragraph.
• Finally, passDocument.SaveToFile(string fileName, FileFormat fileFormat) method to save the document.

To set different text watermark effects on different pages, you only need to obtain the corresponding section of the page, and then refer to the method used above to add it.

As shown in the figure, each page can display different text watermark effects:
