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 ();
