This sample shows how to use colored and uncolored tiling patterns.

C# :

using PDFMosaic;
using System.Drawing;
 
namespace Patterns
{
  class Patterns
  {
    static void Main()
    {
      PDFDocument document = new PDFDocument();
      document.Pages.Add(new PDFPage(PDFPaperFormat.A4));
      PDFCanvas canvas = document.Pages[0].Canvas;
 
      PDFColorRGB red = new PDFColorRGB(255, 0, 0);
      PDFColorRGB green = new PDFColorRGB(0, 255, 0);
      PDFColorRGB blue = new PDFColorRGB(0, 0, 255);
      PDFSolidPen pen = new PDFSolidPen();
 
      PDFColoredTilingBrush tillingbrush = new PDFColoredTilingBrush(50, 50);
      PDFUncoloredTilingBrush untillingbrush = new PDFUncoloredTilingBrush(10, 10);
      canvas = untillingbrush.Canvas;
      canvas.DrawCircle(new PDFSolidPen(green), new PDFSolidBrush(blue), 5, 5, 4);
      untillingbrush.Color = green;
      canvas = tillingbrush.Canvas;
      canvas.DrawEllipse(pen, untillingbrush, 0, 0, 49, 25);
      canvas.RotateTransform(45);
      canvas.DrawRectangle(new PDFSolidBrush(new PDFColorRGB(100, 100, 100)), 33, 5, 10, 20);
      canvas = document.Pages[0].Canvas;
      canvas.DrawRoundedRectangle(pen, tillingbrush, 100, 100, 200, 300, 30);
 
      document.Save("Patterns.pdf", true);
    }
  }
}

Visial Basic.NET :

Imports PDFMosaic
Imports System.Drawing
 
Module Patterns
  Sub Main()
    Dim document As PDFDocument = New PDFDocument()
    document.Pages.Add(New PDFPage(PDFPaperFormat.A4))
    Dim canvas As PDFCanvas = document.Pages(0).Canvas
 
    Dim red As PDFColorRGB = New PDFColorRGB(255, 0, 0)
    Dim green As PDFColorRGB = New PDFColorRGB(0, 255, 0)
    Dim blue As PDFColorRGB = New PDFColorRGB(0, 0, 255)
    Dim pen As PDFSolidPen = New PDFSolidPen()
 
    Dim tillingbrush As PDFColoredTilingBrush = New PDFColoredTilingBrush(50, 50)
    Dim untillingbrush As PDFUncoloredTilingBrush = New PDFUncoloredTilingBrush(10, 10)
    canvas = untillingbrush.Canvas
    canvas.DrawCircle(New PDFSolidPen(green), New PDFSolidBrush(blue), 5, 5, 4)
    untillingbrush.Color = green
    canvas = tillingbrush.Canvas
    canvas.DrawEllipse(pen, untillingbrush, 0, 0, 49, 25)
    canvas.RotateTransform(45)
    canvas.DrawRectangle(New PDFSolidBrush(New PDFColorRGB(100, 100, 100)), 33, 5, 10, 20)
    canvas = document.Pages(0).Canvas
    canvas.DrawRoundedRectangle(pen, tillingbrush, 100, 100, 200, 300, 30)
 
    document.Save("Patterns.pdf", True)
  End Sub
End Module
