C＃保存PPT形狀（msoPicture）作爲圖像w/Office.Interop

Question

我有一個PPT幻燈片與多個圖像。我遍歷每個幻燈片和每個形狀。我想類型msoPicture各自的形狀保存爲圖片：

  foreach (PPT.Slide slide in pptDoc.Slides) 
      { 
       foreach (PPT.Shape shape in slide.Shapes) 
       { 
        if (shape.Type == Microsoft.Office.Core.MsoShapeType.msoPicture) 
        { 

         Image img; 
         //???? Save shape as image 
         img.Save(filename); 
        } 
       } 
      } 

Answer 1

可以使用Shape.Export() method從一個單獨的形狀形成圖像。

例如像這樣：

foreach (PPT.Slide slide in pptDoc.Slides) 
{ 
    foreach (PPT.Shape shape in slide.Shapes) 
    { 
     if (shape.Type == Microsoft.Office.Core.MsoShapeType.msoPicture) 
     { 
      shape.Export(filename, Microsoft.Office.Interop.PowerPoint.PpShapeFormat.ppShapeFormatPNG); 
     } 
    } 
}
