Hi,



I used the following code to fill the shape with picture, but I cannot find any option to control the transparency of picture, please see enclosed code and samples for more details, thank you very much.





Code:



var shape = slide.Shapes.AddAutoShape(ShapeType.Rectangle, 0, 0, presentation.SlideSize.Size.Width, presentation.SlideSize.Size.Height);

shape.FillFormat.FillType = FillType.Picture;

shape.FillFormat.PictureFillFormat.Picture.Image = picture;

shape.FillFormat.PictureFillFormat.PictureFillMode = PictureFillMode.Tile;

shape.FillFormat.PictureFillFormat.Picture.ImageTransform.AddAlphaBiLevelEffect(0.5f);





Best Regards,

Long
