This sample shows how to create an CMYK color space and then create and use a color with that color space.



C# :

using PDFMosaic;
using System.Drawing;
using System;
namespace CMYKColorSpace
    class CMYKColorSpace
        static void Main()
            PDFDocument document = new PDFDocument();
            document.Pages.Add(new PDFPage(PDFPaperFormat.A4));
            PDFCanvas canvas = document.Pages[0].Canvas;
            Random rnd = new Random();
            for(int i = 0; i < 5; ++i)
                PDFColorCMYK colorCMYK = new PDFColorCMYK((byte)rnd.Next(255), (byte)rnd.Next(255), (byte)rnd.Next(255), (byte)rnd.Next(255));
                PDFSolidBrush brushCMYK = new PDFSolidBrush(colorCMYK);
                canvas.DrawRoundedRectangle(brushCMYK, 10 + 20*i, 10 + 20*i, 70, 100, 10);
            document.Save("CMYKColorSpace.pdf", true);


Visial Basic.NET :

Imports PDFMosaic
Imports System.Drawing
Imports System
Module CMYKColorSpace
 Sub Main()
  Dim document As PDFDocument = New PDFDocument()
  document.Pages.Add(New PDFPage(PDFPaperFormat.A4))
  Dim canvas As PDFCanvas = document.Pages(0).Canvas
  Dim rnd As New Random()
  Dim i As Integer
  For i = 0 To 4
  Dim colorCMYK As PDFColorCMYK = New PDFColorCMYK(rnd.Next(255), rnd.Next(255), rnd.Next(255), rnd.Next(255))
  Dim brushCMYK As PDFSolidBrush = New PDFSolidBrush(colorCMYK)
  canvas.DrawRoundedRectangle(brushCMYK, 10 + i*20, 100 + i*20, 70, 100, 10)
  Next i
  document.Save("CMYKColorSpace.pdf", True)
 End Sub
End Module
