问题描述

我怎么能转换成word文档页面图像特别？

How can I convert word document pages to particular images?

我用下面的代码将其转换为 .TIFF 图片

I have used following code to convert it to .tiff image

object varMissing = Type.Missing;

object varFalseValue = false;
object varTrueValue = true;

Microsoft.Office.Interop.Word.Application word = new Microsoft.Office.Interop.Word.Application();
word.ActivePrinter = "Microsoft XPS Document Writer";
object fileName = startupPath + "\\" + filename1;
object falseValue = false;
object trueValue = true;
object missing = Type.Missing;
word.Visible = true;
word.Activate();
Document doc = word.Documents.Open(ref fileName, ref missing,
                    ref falseValue, ref missing, ref missing, ref missing,
                    ref missing, ref missing, ref missing, ref missing,
                    ref missing, ref missing, ref missing, ref missing,
                    ref missing, ref missing);
doc.Activate();

object PrintToFile = true;
object OutputFileName = startupPath + "\\" + filename1.Split('.')[0] + ".tif";

doc.PrintOut(ref varMissing, ref varFalseValue, ref varMissing, 
             ref OutputFileName, ref varMissing, ref varMissing, ref varMissing,
             ref varMissing, ref varMissing, ref varMissing, ref PrintToFile, 
             ref varMissing, ref varMissing, ref varMissing, ref varMissing, 
             ref varMissing, ref varMissing, ref varMissing);

doc.Close(ref varMissing, ref varMissing, ref varMissing);
word.Quit(ref varMissing, ref varMissing, ref varMissing);

//Multi to Single
MemoryStream ms;
Image myImage;

FileStream fs = new FileStream(startupPath + "\\" + filename1.Split('.')[0] + ".tif", FileMode.Open);
fs.Seek(0, SeekOrigin.Begin);

//Here I am getting error....
myImage = Image.FromStream(fs, true, false);

Guid myGuid = myImage.FrameDimensionsList[0];
FrameDimension myDimension = new FrameDimension(myGuid);
int myPageCount = myImage.GetFrameCount(myDimension);

for (int i = 0; i < myPageCount; i++)
{
      ms = new MemoryStream();
      myImage.SelectActiveFrame(myDimension, i);
      myImage.Save(string.Format(startupPath + "\\" + filename1.Split('.')[0] + ".tif", i), ImageFormat.Tiff);
}

fs.Close();

但是，当我试图文件流转换为图像它给了我像

But when I am trying to convert file stream to Image it gives me error like

Parameter is not valid.

是否有任何其他方式Word文件转换为图像文件？
我不能用它可在市场上卖出的dll文件，但我需要使用微软的核心互操作DLL。
以便请谁能建议我的链接或方式转换.doc文件为JPG格式。

Is there any other way to convert word file to image file?? I cannot use the dlls which are available in market for sell but I need to use the Microsoft's core interop dll. So please can anyone suggest me the link or way to convert .doc file to .jpg.

推荐答案

您可以将.doc文件图像波纹管使用它的代码为我工作。

You can convert Doc file to image using bellow code it worked for me.

var docPath = Path.Combine(startupPath, filename1);
var app = new Microsoft.Office.Interop.Word.Application();

MessageFilter.Register();

app.Visible = true;

var doc = app.Documents.Open(docPath);

doc.ShowGrammaticalErrors = false;
doc.ShowRevisions = false;
doc.ShowSpellingErrors = false;

if (!Directory.Exists(startupPath + "\\" + filename1.Split('.')[0]))
{
     Directory.CreateDirectory(startupPath + "\\" + filename1.Split('.')[0]);
}

//Opens the word document and fetch each page and converts to image
foreach (Microsoft.Office.Interop.Word.Window window in doc.Windows)
{
      foreach (Microsoft.Office.Interop.Word.Pane pane in window.Panes)
      {
            for (var i = 1; i <= pane.Pages.Count; i++)
            {
                 var page = pane.Pages[i];
                 var bits = page.EnhMetaFileBits;
                 var target = Path.Combine(startupPath + "\\" + filename1.Split('.')[0], string.Format("{1}_page_{0}", i, filename1.Split('.')[0]));

                 try
                 {
                     using (var ms = new MemoryStream((byte[])(bits)))
                     {
                          var image = System.Drawing.Image.FromStream(ms);
                          var pngTarget = Path.ChangeExtension(target, "png");
                          image.Save(pngTarget, ImageFormat.Png);
                     }
                 }
                 catch (System.Exception ex)
                 { }
         }
    }
}
doc.Close(Type.Missing, Type.Missing, Type.Missing);
app.Quit(Type.Missing, Type.Missing, Type.Missing);
MessageFilter.Revoke();
