Dialog Based Initialization

The Color Conversion C API 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:

   HANDLE ClrHandle;   
    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:

   L_ClrDlg(DLG_LAB, NULL, &ClrHandle, NULL);

3. Convert from RGB to CIELab as follows:

   L_ClrConvert(ClrHandle, pRGBData, pLABData, nWidth, nHeight, nInAlign, nOutAlign);

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

   L_ClrFree(ClrHandle);
