c#/vb.net 插入、提取 word 批注中的图片-凯发线上登陆下载网址

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)

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
