Dialog Based Initialization

The Color Conversion C DLL 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);
