LEAD Technologies, Inc

Print a Real Image Size in Inches

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: <LEADTOOLS_INSTALLDIR>\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
    ToolStripMenuItem optionsToolStripMenuItem Options
  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
