'PixelFormat' is an ambiguous reference between 'System.Drawing.Imaging.PixelFormat'

Hi
What could be wrong here?

‘PixelFormat’ is an ambiguous reference between ‘System.Drawing.Imaging.PixelFormat’ and ‘OpenTK.Graphics.OpenGL.PixelFormat’
‘System.Drawing.Imaging.PixelFormat’ does not contain a definition for ‘Bgr’

I do the same as in the example that works. For me it does not work.


GL.TexImage2D(TextureTarget.Texture2D, 0, PixelInternalFormat.Rgb8, _texture.Width, _texture.Height, 0, PixelFormat.Bgr, PixelType.UnsignedByte, _texture.MIplImage.imageData);




       private void View3DGlControl_Load(object sender, EventArgs e)
        {
            _glLoaded = true;

            GL.ClearColor(0.0f, 0.0f, 0.0f, 0.0f);
            SetupViewport();

            #region Create texture for the 3D Point clouds
            int repeat = (int)OpenTK.Graphics.OpenGL.All.Repeat;
            int linear = (int)OpenTK.Graphics.OpenGL.All.Linear;
            GL.Enable(EnableCap.CullFace);
            GL.Enable(EnableCap.Texture2D);
            _textures = new int[1];
            GL.GenTextures(1, _textures);
            GL.BindTexture(TextureTarget.Texture2D, _textures[0]);

            /* GL.TexParameterI(TextureTarget.Texture2D, TextureParameterName.TextureWrapS, ref repeat);
             GL.TexParameterI(TextureTarget.Texture2D, TextureParameterName.TextureWrapT, ref repeat);
             GL.TexParameterI(TextureTarget.Texture2D, TextureParameterName.TextureMagFilter, ref linear);
             GL.TexParameterI(TextureTarget.Texture2D, TextureParameterName.TextureMinFilter, ref linear);*/


            GL.TexParameter(TextureTarget.Texture2D, TextureParameterName.TextureWrapS, repeat);
            GL.TexParameter(TextureTarget.Texture2D, TextureParameterName.TextureWrapT, repeat);
            GL.TexParameter(TextureTarget.Texture2D, TextureParameterName.TextureMagFilter, linear);
            GL.TexParameter(TextureTarget.Texture2D, TextureParameterName.TextureMinFilter, linear);


            GL.TexEnv(TextureEnvTarget.TextureEnv, TextureEnvParameter.TextureEnvMode, (int)OpenTK.Graphics.OpenGL.All.Decal);
            GL.ShadeModel(ShadingModel.Smooth);
            GL.Hint(HintTarget.PerspectiveCorrectionHint, HintMode.Nicest);
            GL.BindTexture(TextureTarget.Texture2D, 1);

            Size size = _left.Size;
            int maxDim = Math.Max(size.Width, size.Height);
            using (Image<Bgr, Byte> squareImg = new Image<Bgr, byte>(maxDim, maxDim))
            {
                Rectangle roi = new Rectangle(maxDim / 2 - size.Width / 2, maxDim / 2 - size.Height / 2, size.Width, size.Height);
                squareImg.ROI = roi;
                CvInvoke.cvCopy(_left, squareImg, IntPtr.Zero);
                squareImg.ROI = Rectangle.Empty;
                _texture = squareImg.Resize(256, 256, Emgu.CV.CvEnum.INTER.CV_INTER_CUBIC, true);
                _texture._Flip(Emgu.CV.CvEnum.FLIP.VERTICAL);
                GL.TexImage2D(TextureTarget.Texture2D, 0, PixelInternalFormat.Rgb8, _texture.Width, _texture.Height, 0, PixelFormat.Bgr, PixelType.UnsignedByte, _texture.MIplImage.imageData);
            }
            #endregion
         
        }

Thanks for reply.

This should be self-explanatory. Two different modules both define the name “PixelFormat”, so it’s ambiguous which one it refers to.

Replace any occurrences of “PixelFormat” with either “System.Drawing.Imaging.PixelFormat” or “OpenTK.Graphics.OpenGL.PixelFormat”.

You use “PixelFormat.Bgr” which it interprets as “System.Drawing.Imaging.PixelFormat.Bgr” when you wanted “OpenTK.Graphics.OpenGL.PixelFormat.Bgr”.

But beyond that, this is a general C# programming question, not an OpenGL question.

Thanks. It’s working
