redraw transparent image

[walid86]

i have a png file, or gif if that makes any difference which i am redrawing using GDI+.

Bitmap b6 = new Bitmap(525, 525, System.Drawing.Imaging.PixelFormat.Format32bppArgb);
            b6.SetResolution(300, 300);

            using (Graphics grPhoto = Graphics.FromImage(b6))
            {

                grPhoto.CompositingMode = CompositingMode.SourceCopy;
                grPhoto.SmoothingMode = SmoothingMode.HighQuality;
                grPhoto.InterpolationMode = InterpolationMode.HighQualityBicubic;
                grPhoto.PixelOffsetMode = PixelOffsetMode.HighQuality;
                grPhoto.CompositingQuality = CompositingQuality.HighQuality;
                
                //now do the crop 

                grPhoto.DrawImage(loadedImage1, imageBounds1.Location.X, imageBounds1.Location.Y);

            }

The original image is transparent, but when i re draw, the background is black.. any fix for this?

The image has transparency inside the picturebox initally.
