Get RGB from pixel via image buffer

Question

Hi I am new to C# and im working on image processing im using this bit of code to invert the pixels on an image how do I extract the RGB values from a pixel in C# using the image buffer? Thanks. unsafe { byte* p = (byte *)(void *)pBuffer; int nWidth = Width * 3; for(int y = 0; y { for(int x = 0; x { p[0] = (byte)(255-p[0]); p++;

Try something like this: Color col = new Color(); Bitmap pic = // code to get the bitmap - perhaps an OpenFileDialog col = pic.GetPixel(e.X e.Y); SomeTextBox1.Text = col.R.ToString(); SomeTextBox2.Text = col.G.ToString(); SomeTextBox3.Text = col.B.ToString();
