Take the following steps to start a project and to add some code that prints an image:

1. Start Visual Studio .NET

2. Choose File->New->Project... from the menu

3. In the New Project dialog box, choose either "Visual C#" or "Visual Basic" in the Projects Type List, and choose "Windows Forms Application" in the Templates List

4. Enter the project name as "PrintImageTutorial" in the Name field, and then click OK. If desired, type a new location for your project or select a directory using the Browse button, and then click OK

5. In the "Solution Explorer" window, right-click on the project and select "Add Reference..." from the context menu. In the "Add Reference" dialog box, select the ".NET" tab and select the following components - If you used the LEADTOOLS Setup, the LEADTOOLS components will be visible under the .NET components and you should select them from the list, otherwise, select the "Browse" tab and browse to the LEADTOOLS setup folder – Default location is: C:\Program Files (x86)\LEAD Technologies\LEADTOOLS 16.5\Bin\Dotnet\Win32

   • Leadtools.dll
   • Leadtools.Codecs.dll
   • Leadtools.WinForms.dll
   • Leadtools.Codecs.Bmp.dll
   • Leadtools.Codecs.Cmp.dll
   • Leadtools.Codecs.Fax.dll
   • Leadtools.Codecs.Tif.dll

   The above references will allow you to use BMP, JPG and TIF files. If you require more file formats, please refer to the File Formats section in the Files To Be Included With Your Application topic

6. Since we are going to use the Win32 (x86) assembly references, we must change the build target of this project to be x86. Select Project->PrintImageTutorial Properties from the main menu and in the project properties dialog, and follow the following steps:

   • For the C# project, select the Build tab, select "All Configurations" from the Configuration drop down selection box and select "x86" from the Platform target drop down selection box

   • For the VB project, select the Compile tab and select "All Configurations" from the Configuration drop down selection box. Click the Advanced Compile Options button and select "x86" from the Target CPU drop down selection box and click OK to close the dialog.

7. Make sure Form1 is in design view. From the toolbox (View->Toolbox from the main menu), drag and drop a MenuStrip control to the form. Click on the new menuStrip1 control and add the following top-level menu items:

   Type	Name	Text	Shortcut Keys
   ToolStripMenuItem	fileToolStripMenuItem	File
   ToolStripMenuItem	pageToolStripMenuItem	Page

8. Select the "File" menu item and add the following sub items:

   Type	Name	Text	Shortcut Keys
   ToolStripMenuItem	openToolStripMenuItem	Open...	Ctrl+O
   ToolStripSeparator	toolStripMenuItem1
   ToolStripMenuItem	printPreviewToolStripMenuItem	Print preview
   ToolStripMenuItem	printSetupToolStripMenuItem	Print setup...
   ToolStripMenuItem	printToolStripMenuItem	Print...	Ctrl+P
   ToolStripSeparator	toolStripMenuItem2
   ToolStripMenuItem	exitToolStripMenuItem	Exit

9. Select the "Page" menu item and add the following sub items:

   Type	Name	Text	Shortcut Keys
   ToolStripMenuItem	firstPageToolStripMenuItem	First page
   ToolStripMenuItem	previousPageToolStripMenuItem	Previous page
   ToolStripMenuItem	nextPageToolStripMenuItem	Next page
   ToolStripMenuItem	lastPageToolStripMenuItem	Last page

10. Select the "Options" menu item and add the following sub items:

    Type	Name	Text	Shortcut Keys
    ToolStripMenuItem	usePageMarginsToolStripMenuItem	Use page margins
    ToolStripMenuItem	fitImageToPageToolStripMenuItem	Fit image to page

11. Go to the toolbox (View->Toolbox) and drag and drop an instance of LEADTOOLS RasterImageViewer control to the form (If you do not have RasterImageViewer in your toolbox, select Tools->Choose Toolbox Items from the main menu. Select the ".NET Framework Components" tab and select the "RasterImageViewer" component). After you dropped the new control to the form, change the following properties of "rasterImageViewer1" to the specified values:

    Property	Value
    Dock	Fill
    UseDpi	True

12. Switch to Form1 code view (right-click Form1 in the solution explorer then select View Code) and add the following lines at the beginning of the file:

    [Visual Basic]

    
    Imports System.Drawing.Printing
    Imports Leadtools
    Imports Leadtools.Codecs
    Imports Leadtools.WinForms
    

    [C#]

    
    using System.Drawing.Printing;
    using Leadtools;
    using Leadtools.Codecs;
    using Leadtools.WinForms;
    

13. Add the following private variables to Form1:

    [Visual Basic]

    
    ' The RasterCodecs object to use when loading images
    Private _rasterCodecs As RasterCodecs
    ' The PrintDocument object we will be using throughout this demo
    Private _printDocument As PrintDocument
    ' The current page number bring printed
    Private _currentPrintPageNumber As Integer
    ' The current image file name
    Private _currentImageFileName As String
    

    [C#]

    
    // The RasterCodecs object to use when loading images
    private RasterCodecs _rasterCodecs;
    // The PrintDocument object we will be using throughout this demo
    private PrintDocument _printDocument;
    // The current page number bring printed
    private int _currentPrintPageNumber;
    // The current image file name
    private string _currentImageFileName;
