Why does SizeMode StretchImage have the following effect and how can I fix it?
gradient Code for example:
Bitmap bitmap = new Bitmap(1,1,PixelFormat.Format24bppRgb);
bitmap.SetPixel(0,0, Color.Black);
pictureBox1.Image = bitmap;

That's because graphics get interpolated by default. You can try subclassing PictureBox, override OnPaint, set smoothing and interpolation properties of the Graphics instance stored with the PaintEventArgs to lowest quality and call the base implementation. – Ray Mar 10 '18 at 20:39
