在 Word 文檔中插入圖片水印

詳細(xì)步驟如下：

創(chuàng)建Document類的對象。

通過Document.LoadFromFile()方法從磁盤加載 Word 文檔。

使用自定義方法 InsertImageWatermark()， 在文檔中插入圖片水印。

最后，通過Doucment.SaveToFile()方法保存文檔。

C#

using System;
using System.Drawing;
using Spire.Doc;
using Spire.Doc.Documents;
namespace InsertWatermark
{
internal class Program
{
static void Main(string[] args)
{
//創(chuàng)建Document類的對象
Document document = new Document();
//從磁盤加載 Word 文檔
document.LoadFromFile(@"西雙版納.docx");
//插入圖片水印
InsertImageWatermark(document);

//保存文檔
document.SaveToFile("西雙版納 圖片水印.docx", FileFormat.Docx);
}
private static void InsertImageWatermark(Document document)
{
PictureWatermark picture = new PictureWatermark();
picture.Picture = Image.FromFile(@"水印.png");
picture.Scaling = 200;
picture.IsWashout = false;
document.Watermark = picture;
}
}
}

VB.NET

Imports System
Imports System.Drawing
Imports Spire.Doc
Imports Spire.Doc.Documents
Module Program
Sub Main(args As String())
'創(chuàng)建Document類的對象
Dim document As New Document()
'從磁盤加載 Word 文檔
document.LoadFromFile("西雙版納.docx")
'插入圖片水印
InsertImageWatermark(document)
'保存文檔
document.SaveToFile("西雙版納 圖片水印.docx", FileFormat.Docx)
End Sub
Private Sub InsertImageWatermark(ByVal document As Document)
Dim picture As New PictureWatermark()
picture.Picture = Image.FromFile("水印.png")
picture.Scaling = 250
picture.IsWashout = False
document.Watermark = picture
End Sub
End Module
