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(¶ms, 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, ¶ms);
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 ();
