New Post: Create a grayscale png image from a byte buffer

Hello everyone,

I would like to create a grayscale png image from a byte buffer containing the 8bits gray values. The following code show how i do until now. This is clearly not the best way so what is the good one ?

I don't know how to read my one channel pixels byte array .

Thank you for your help.

        //convert raw buffer to grayscale 8 bits png image
        static void SaveGrayscale8bitsPngImage(byte[] pixels, string path)
        {
            MagickReadSettings settings = new MagickReadSettings();
            settings.Width = 640;
            settings.Height = 480;
            settings.PixelStorage = new PixelStorageSettings(StorageType.Char, "R");

            using (MagickImage image = new MagickImage(pixels, settings))
            {
                image.Grayscale(PixelIntensityMethod.Average);
                image.Format = MagickFormat.Png;
                image.SetDefine(MagickFormat.Png, "color-type", "0"); //0 = grayscale image 
                image.SetDefine(MagickFormat.Png, "bit-depth", "8"); //number of bits per index
                image.SetDefine(MagickFormat.Png, "compression-level", "9"); //valid values are 0 through 9, with 0 providing the least but fastest compression and 9 usually providing the best and always the slowest.

                image.Write(path);
            }
        }
