C#将图像形式PowerPoint复制到Word [英] C# copy image form PowerPoint to Word

问题描述

我需要一个应用程序将PowerPoint中的文本和图像复制到Word.我使用以下库:Microsoft.Office.Interop.PowerPoint和Microsoft.Office.Interop.Word.

I need a application to copy text and images form PowerPoint to Word. I use this libraries: Microsoft.Office.Interop.PowerPoint and Microsoft.Office.Interop.Word.

文本易于传递，但是当我在PowerPoint中发现仅包含图像的形状时，它显示此错误:"发生通用错误GDI + "，在此部分代码中:

The text s easy to transfer, but when I find in PowerPoint a shape containing only a image, it show this error: "A generic error occured GDI+", at this part of code:

foreach (PowerPoint.Shape shape in slide.Shapes)
{
   if (shape.HasTextFrame != MsoTriState.msoTrue){
      shape.Copy();
      Image img = (Image)Clipboard.GetData(DataFormats.Bitmap);
      string filepath = Environment.SpecialFolder.Desktop + "\\img.jpg";
      if (File.Exists(filepath))
      {
         File.Delete(filepath);
      }
      img.Save(filepath);
      doc.Shapes.AddPicture(filepath, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing, ref missing);
   }
}

在这种情况下，如何将包含图像的形状从PowerPoint复制到Word? 欢迎任何帮助.我更喜欢一些代码示例.

How can I copy a shape containing a image from PowerPoint to Word in this cirumstances? Any help is welcome. I prefer some code sample.

谢谢.

推荐答案

如果您以这种方式重写代码，它将起作用吗? GetImage将执行自动转换以确保它是图像.如果您知道这是位图，则可以在代码中包含我所进行的检查，以确保剪贴板实际上包含图像.

If you rewrite your code like this, will it work? GetImage will do an automatic conversion to make sure it's an image. If you know it's a bitmap you could include the check I have in the code to ensure the clipboard actually contains an image.

shape.Copy();
bool imgOk = Clipboard.ContainsImage();
if (imgOk)
{
    Image img = Clipboard.GetImage();
    MessageBox.Show(imgOk.ToString());
    string filepath = @"c:\temp\img.jpg";
    if (File.Exists(filepath))
    {
        File.Delete(filepath);
    }
    img.Save(filepath);
}
