Conversion Given an ICM Profile

1. Define the following global variables:

   HANDLE ClrHandle;   
   CONVERSION_PARAMS params;   
   BYTE RGBColor[3];   
   BYTE ColorSpace[4]; 

2. Set the conversion options by filling a CONVERSION_PARAMS structure:

   memset(&params, 0, sizeof(CONVERSION_PARAMS));   
      
   params.uStructSize = sizeof(CONVERSION_PARAMS);   
   params.nMethod = USE_CUSTOM_ICC;   
   params.nActiveMethod = USE_CUSTOM_ICC;   
   params.pWpoint = (LPWHITEPOINT)malloc(sizeof(WHITEPOINT));   
   params.pWpoint->nWhitePoint = CIELAB_D50;   
      
   params.pMemInputProfile = NULL;   
   params.pMemOutputProfile = NULL;   
      
   lstrcpy(params.sInputProfile, TEXT("C:\\MyCMYKProfile.ICM"));   
   lstrcpy(params.sOutputProfile, TEXT("C:\\MyRGBProfile.ICM")); 

3. Initialize the color conversion handle with L_ClrInit():

   L_ClrInit(&ClrHandle, CCS_CMYK, CCS_RGB, &params);

4. Now, do the conversion:

   ColorSpace[0] = 100;   
   ColorSpace[1] = 100;   
   ColorSpace[2] = 100;   
   ColorSpace[3] = 100; 
    
   L_ClrConvert(ClrHandle, ColorSpace, RGBColor, 1, 1, 0, 0); 

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

   L_ClrFree(ClrHandle);
