Creating an ICC Profile

The following steps create a new ICC profile, and add to it 3 tags. The first tag will be created from scratch. The second one will be taken from an existing ICC profile, modified and then added to the new ICC profile. The final tag will be taken from an existing ICC profile and added to the new ICC profile without modifications.

1. Start Microsoft Visual Studio 2005.
2. Choose File->New->Project… from the menu.
3. In the New Project dialog box, choose Other Languages from the Project Types list, then choose either "Visual C#" or "VB" in the, and then choose "Windows Application" in the Templates List.
4. Type the project name as "Creating an ICC Profile" in the Name field, and then choose OK. If desired, type a new location for your project or select a directory using the Browse button, and then choose OK.

5. In the "Solution Explorer" window, right-click on "Creating an ICC Profile" project, and select "Add Reference…" from the context menu. In the "Add Reference" dialog box, select the "Browse" tab and browse to the "C:\LEADTOOLS 20\Bin\Dotnet\Win32" folder and select the following DLLs:

   • Leadtools.dll
   • Leadtools.Codecs.dll
   • Leadtools.ColorConversion.dll

   and then click the OK button to add the above DLLs to the application.

6. Make sure Form1 is in design view. From the toolbox (View->Toolbox), add a Button control (Text = "ICC").

7. 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:

   VB

   Imports Leadtools 
   Imports Leadtools.Codecs 
   Imports Leadtools.ColorConversion 

   C#

   using Leadtools; 
   using Leadtools.Codecs; 
   using Leadtools.ColorConversion; 

8. double-click the button1 Button on the form to add the event handler for it and add the following code:

   VB
