本篇文章将介绍如何使用Spire.Doc for .NET来实现将图片插入到Word批注以及提取Word批注中的图片。

插入图片到Word批注

//创建Document类的对象，加载文档
Document doc = new Document();
doc.LoadFromFile("testfile.docx");

//获取第一个批注
Comment comment = doc.Comments[0];

//实例化DocPicture类，加载图片
DocPicture docPicture = new DocPicture(doc);
Image img = Image.FromFile("img1.png");
docPicture.LoadImage(img);

//插入图片到批注
comment.Body.AddParagraph().ChildObjects.Add(docPicture);

//保存文档
doc.SaveToFile("result.docx", FileFormat.Docx2013);

'创建Document类的对象，加载文档
Dim doc As Document = New Document
doc.LoadFromFile("testfile.docx")

'获取第一个批注
Dim comment As Comment = doc.Comments(0)

'实例化DocPicture类，加载图片
Dim docPicture As DocPicture = New DocPicture(doc)
Dim img As Image = Image.FromFile("img1.png")
docPicture.LoadImage(img)

'插入图片到批注
comment.Body.AddParagraph.ChildObjects.Add(docPicture)

'保存文档
doc.SaveToFile("result.docx", FileFormat.Docx2013)

图片插入效果：

读取Word批注中的图片

//创建实例，加载文档
Document doc = new Document();
doc.LoadFromFile("sample.docx");

int index = 0;

//遍历批注,获取图片
foreach (Comment comment in doc.Comments)
{
    foreach (Paragraph p in comment.Body.Paragraphs)
    {
        foreach (DocumentObject docObject in p.ChildObjects)
        {
            if (docObject.DocumentObjectType == DocumentObjectType.Picture)
            {
                DocPicture picture = docObject as DocPicture;
                String imageName = String.Format("图片{0}.png", index);
                picture.Image.Save(imageName, System.Drawing.Imaging.ImageFormat.Png);
                index++;
            }
        }
    }
}

'创建实例，加载文档
Dim doc As Document = New Document
doc.LoadFromFile("sample.docx")

Dim index As Integer = 0

'遍历批注,获取图片
For Each comment As Comment In doc.Comments
    For Each p As Paragraph In comment.Body.Paragraphs
        For Each docObject As DocumentObject In p.ChildObjects
            If (docObject.DocumentObjectType = DocumentObjectType.Picture) Then
                Dim picture As DocPicture = CType(docObject,DocPicture)
                Dim imageName As String = String.Format("图片{0}.png", index)
                picture.Image.Save(imageName, System.Drawing.Imaging.ImageFormat.Png)
                index = (index + 1)
            End If
            
        Next
    Next
Next
