una cosa di questo genere intendo:
codice:
Dim newGraphic As Graphics = Graphics.FromImage(newBmp)

                

                    newGraphic.SmoothingMode = Drawing2D.SmoothingMode.AntiAlias

                    newGraphic.InterpolationMode = Drawing2D.InterpolationMode.HighQualityBicubic

                    newGraphic.DrawImage(upBmp, newX, newY, newWidth, newHeight)

                    newBmp.Save(MapPath(filePath), Imaging.ImageFormat.Png)
