C#将PPT形状(msoPicture)保存为带Office.Interop的图像 [英] C# Save PPT Shape (msoPicture) as Image w/ Office.Interop

问题描述

我有一个包含多张图片的PPT幻灯片.我正在遍历每个幻灯片和每个形状.我想将msoPicture类型的每种形状另存为Image:

I have a PPT slide deck with multiple images. I am iterating through each slide and each shape. I would like to save each shape of type msoPicture as an Image:

            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);
                    }
                }
            }

推荐答案

您可以使用

You can use the Shape.Export() method to create an image from an individual shape.

例如这样的

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);
        }
    }
}
