Dialog Based Initialization

The Color Conversion C++ Class Library provides a color space dialog that can be used to initialize a conversion. To do a dialog based initialization follow the steps below:

1. Define the following global variables:

   LColor clr; 
   L_UCHAR *pRGBData; 
   L_UCHAR *pLABData; 
   L_INT nWidth; 
   L_INT nHeight; 
   L_INT nInAlign; 
   L_INT nOutAlign; 

2. Display the color space dialog box to initialize as follows:

   clr.ClrDlg(DLG_LAB, NULL, NULL); 

3. Convert from RGB to CIELab as follows:

   clr.Convert(pRGBData, pLABData, nWidth, nHeight, nInAlign, nOutAlign); 

4. At the end, free the color conversion object:

   clr.Free();
