[h_r_s_h]

I want to draw images using pixel datas. And I found a function "ReadPixels()". But I don't know how to use this, and how to make the byte array .

For example, the 2D pixel data matrix 2*2 (r,g,b,a) is as follow

{[(100,100,100,100), (100,100,100,100)],

[(100,100,100,100), (100,100,100,100)]}

how should I program?

Thanks;

The following is my uncompleted code.

public class AppMain
	{
		private static GraphicsContext graphics;
		
		private static int width;
		private static int height;
		
		public static void Main (string[] args)
		{
			Initialize ();

			while (true) {
				SystemEvents.CheckEvents ();
				Update ();
				Render ();
			}
		}

		public static void Initialize ()
		{
			graphics = new GraphicsContext ();
			
			width = 300;
			height =300;
		}

		public static void Update ()
		{
			// Query gamepad for current state
			var gamePadData = GamePad.GetData (0);
		}

		public static void Render ()
		{
			// Clear the screen
			graphics.SetClearColor (1.0f, 1.0f, 1.0f, 1.0f);
			graphics.Clear ();
			
			byte [] array = new byte [width*height*4];
			for(int y=0;y<height;y++){
				for(int x=0;x<width;x++){
					array[4*(x + y*width)] = 50;
					array[4*(x + y*width)+1] = 100;
					array[4*(x + y*width)+2] = 150;
					array[4*(x + y*width)+3] = 0;
				}
			}
			
			graphics.ReadPixels(array,PixelFormat.Rgba,0,0,width,height);
			graphics.SwapBuffers ();
		}
	}

Maybe, my question was solved by code in "Pss/sample/Graphics/PrimitiveSample". Thanks!
