android-canvas-draw.cs

var canvas = new Canvas();
canvas.SetViewport(256, 256);
var bitMatrix = new bool[256][]; //bool[256][256]
//Generate the bitMatrix
//...
var blackPaint = new Paint {Color = Color.Black};
var whitePaint = new Paint {Color = Color.White};
for (var x = 0; x < 256; x++) {
  for (var y = 0; y < 256; y++) {
    canvas.DrawPoint(x,y, bitMatrix[x][y] ? blackPaint : whitePaint);
  }
}

_image.SetImageBitmap(bitmap);
