Extract All Images from Shapes in Visio

The Page Class object represents the drawing area of a foreground page or a background page. The Shapes property exposed by the Diagram class supports a collection of Aspose.Diagram.Shape objects. This property can be used to extract all the images from a particular page.

The following piece of code extracts all the images from a particular page.

 //Call the diagram constructor to load diagram from a VSD file
            Diagram diagram = new Diagram("ExtractImageFromShape.vsd");

            //enter page index i.e. 0 for first one
            foreach (Shape shape in diagram.Pages[0].Shapes)
            {
                //Filter shapes by type Foreign
                if (shape.Type == Aspose.Diagram.TypeValue.Foreign)
                {
                    using (System.IO.MemoryStream stream = new System.IO.MemoryStream(shape.ForeignData.Value))
                    {
                        //Load memory stream into bitmap object
                        System.Drawing.Bitmap bitmap = new System.Drawing.Bitmap(stream);

                        // save bmp here
                        bitmap.Save("ExtractedShape" + shape.ID + ".bmp");
                    }
                }
            }
