C# 将 PPT 形状 (msoPicture) 保存为图像 w/ Office.Interop

Question

我有一张包含多张图片的 PPT 幻灯片。我正在遍历每张幻灯片和每个形状。我想将 msoPicture 类型的每个形状保存为图像：

            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

您可以使用 Shape.Export() method 从单个形状创建图像。

例如像这样：

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);
        }
    }
}
