Hi Khushboo,

Thank you for posting.

I have observed your comments but I am unable to understand it completely. If you want to extract images from a slide then I would like to share with you that an image is contained inside a Picture frame which is basically a shape. You can iterate through the shapes and check for the the shape if that is a picture frame, as in the code below. Also, you can find any shape as explained in this documentation article and then create a thumbnail of the shape as explained in this documentation article.

Presentation pres = new Presentation(@"D:\Test.pptx");

foreach (Slide slide in pres.Slides)
{
    foreach (IShape shape in slide.Shapes)
    {
        if (shape is PictureFrame)
        {
            //Create Thumbnail Here
        }
    }
}

I hope this will be helpful. Please share if I may help you further in this regard.

Best Regards,

Hi,

Thanks for the reply.
I am able to read image inside shape.PictureFormat.Picture.Image.BinaryData, and cropped position inside shape.PictureFormat.CropTop.

Is there any way to read cropped image BinaryData only.

Presentation pres = new Presentation(@"D:\Test.pptx");

foreach (Slide slide in pres.Slides)
{
    foreach (IShape shape in slide.Shapes)
    {
        if (shape is PictureFrame)
        {
            var img = shape.PictureFormat.Picture.Image;
            var cropFormat = shape.PictureFormat;

            using (Stream stream = File.OpenWrite(""))
            {
                stream.Write(shape.PictureFormat.Picture.Image.BinaryData, 0, shape.PictureFormat.Picture.Image.BinaryData.Length);
            }
        }
    }
}

Hi Khushboo,

I have observed your comments and like to share with you that the cropped image is not saved as another copy of image but the original image appears in a way that it looks cropped. Now, as per your requirements you may create a thumbnail of the shape in the bounds of its appearance as explained in this documentation article.

I hope this will be helpful. Please share if I may help you further in this regard.

Best Regards,
