RectangleF rect = new RectangleF(50, 50, width, height);
//insert a shape
IAutoShape shape= presentation.Slides[0].Shapes.AppendShape(ShapeType.Rectangle, rect);
//fill the shape with image
shape.Fill.FillType = Spire.Presentation.Drawing.FillFormatType.Picture;
shape.Fill.PictureFill.Picture.Url = imagePath;
shape.Fill.PictureFill.FillType = Spire.Presentation.Drawing.PictureFillType.Stretch;
shape.Line.FillFormat.SolidFillColor.Color = Color.Transparent;

In the code above, I created a rectangle based on the size of the image. However, if you want to insert image at the spefied location with fixed size, you can set the four paramters when you initialize the RactangeF object. X and Y determine the image position, Width and Height determine the image size.

RectangleF rect = new RectangleF(x, y, width, height);
