Mosaic fill page.

[jaka1-newbie]

I want to get pdf page a4 size filled by math examples:

int number1 = 0;
int number2 = 0;
int operators = 0;
string answer;
int mathProblem = 0;
Random number = new Random();
int i = 1;

do
{
    number1 = number.Next(1, 10);
    number2 = number.Next(1, 10);
    operators = number.Next(1, 5);  // 1 = add, 2 = minus, 3 = multiply, 4 = divide

	switch (operators)
    {
        case 1:
            answer = number1.ToString()+" + "+number2.ToString()+" =   ";
            break;
        case 2:
            answer = number1.ToString()+" - "+number2.ToString()+" =   ";
            break;
        case 3:
            answer = number1.ToString()+" * "+number2.ToString()+" =   ";
            break;
        case 4:
            answer = number1.ToString()+" / "+number2.ToString()+" =   ";
            break;
        default:
			answer = "";
            break;

    }
	
	using (MagickImage image = new MagickImage())
	{
	  MagickReadSettings settings = new MagickReadSettings()
	  {
	    BackgroundColor = MagickColors.LightBlue, // -background lightblue
	    FillColor = MagickColors.Black, // -fill black
	    Font = "Arial", // -font Arial 
		Density = new Density(300),
	  };
	
	  image.Read("caption:"+answer+"", settings);
	  image.Write(i.ToString()+".png"); 
	}
	i++;
} while (i<4);

using (var images = new MagickImageCollection())
{
    // Add the first image
    var first = new MagickImage("1.png");
    images.Add(first);

    // Add the second image
    var second = new MagickImage("2.png");
    images.Add(second);

	// Add next image
    var third = new MagickImage("3.png");
    images.Add(third);
    // Create a mosaic from all images
    using(var result = images.Mosaic())
    {
      // Save the result
      result.Write("Mosaic.png");
   }
}

1. Why is it a column and not a row?
   Edit: using label instead of caption wil do row. What difference?
2. Why doesn't mosaic work?
