Conversion Given an ICM Profile

1. Define the following global variables:

   LColor clr; 
   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 object with LColor::Initialize():

   clr.Initialize(CCS_CMYK, CCS_RGB, &params); 

4. Now, do the conversion:

   ColorSpace[0] = 100; 
   ColorSpace[1] = 100; 
   ColorSpace[2] = 100; 
   ColorSpace[3] = 100; 
    
   clr.Convert(ColorSpace, RGBColor, 1, 1, 0, 0); 

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

   clr.Free();
