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();
