文字水印和图片水印是Word文档中的两种水印。文本水印总是显示一些与单词上下文相关的附加信息。而图像水印用于使Word文档更具吸引力。本节将演示如何使用 Spire.Doc 在 C# 中为 Word 文档添加文本水印和图像水印。

在 C# 中添加图像水印：

using Spire.Doc;
namespace SetImageWatermark
{
class Program
{
static void Main(string[] args)
{
{
//create a new instance of Document and load the document from file.
Document doc = new Document();
doc.LoadFromFile("Sample.docx", FileFormat.Docx2013);

//create a new instance of the PictureWatermark and load the picture from file.
PictureWatermark picture = new PictureWatermark();
picture.Picture = System.Drawing.Image.FromFile("logo.png");

//set the image watermark scaling and Washout property
picture.Scaling = 20;
picture.IsWashout = false;

//add the picture watermark
doc.Watermark = picture;

//save the document to file
doc.SaveToFile("ImageWatermark.docx", FileFormat.Docx2013);

}
}
}
}

在 C# 中添加文本水印:

using Spire.Doc;
using Spire.Doc.Documents;
using System.Drawing;

{
class Program
{
static void Main(string[] args)
{
{
//create a new instance of Document and load the document from file.
Document doc = new Document();
doc.LoadFromFile("Sample.docx", FileFormat.Docx2013);

//create a new instance of the TextWatermark
TextWatermark txtWatermark = new TextWatermark();

//set the text watermark with text string, font, color and layout.
txtWatermark.Text = "Confidential";
txtWatermark.FontSize = 45;
txtWatermark.Color = Color.Green;
txtWatermark.Layout = WatermarkLayout.Diagonal;

//add the text watermark
doc.Watermark = txtWatermark;

//save the file.
doc.SaveToFile("TextWatermark.docx", FileFormat.Docx2013);
