This is managed direct draw I created a bmp within the vs.net ide so I''m using white as the transparent color. I did this code but it doesnt hid the value. It does hide the white but turns it blue which i believe is the default surface color. Please help me define the surface transparency. SurfaceDescription desc = new SurfaceDescription(); SurfaceCaps caps = new SurfaceCaps(); localClipper = new Clipper(localDevice); localClipper.Window = owner; desc.SurfaceCaps.PrimarySurface = true; surfacePrimary = new Surface(desc, localDevice); surfacePrimary.Clipper = localClipper; desc.Clear(); desc.SurfaceCaps.OffScreenPlain = true; desc.Width = surfacePrimary.SurfaceDescription.Width; desc.Height = surfacePrimary.SurfaceDescription.Height; surfaceSecondary = new Surface(desc, localDevice); surfaceSecondary.FillStyle = 0; Bitmap bmp = new Bitmap(Image.FromFile("c:\\c#games\\JumpMan\\JumpMan.bmp", true)); bmp.MakeTransparent(Color.White); desc.Width = bmp.Width; desc.Height = bmp.Height; surfaceManSprite = new Surface(bmp, desc, localDevice); surfaceManSprite.FillStyle = 1; ColorKey ck = new ColorKey(); ck.ColorSpaceHighValue = -1; ck.ColorSpaceLowValue = -1; surfaceManSprite.SetColorKey(ColorKeyFlags.SourceDraw, ck); thanks, nick
