C++ (Cpp) RGBtoCMYK Examples

Example #1

CChromaMask::CChromaMask(CChromaDlg* pDlg)
{
	int			i;
   	FRMTYPEINFO TypeInfo;
   	BOOL        EnableFade;

	m_pDlg 		= pDlg;

   	EnableFade = TypeInfo.DataType != FDT_LINEART && TypeInfo.DataType != FDT_PALETTECOLOR;
	ChromaCombineMode = SHAPE_ADD;
   	Fade = EnableFade? 10 : 0;
   	Delete = FALSE;
   	ActiveChromaMask = Mask = 0;

   	for (i=0; i < NUM_CHROMAMASKS; i++)
	{
   		MaskRange[i] = 10;
    	MaskColor[i].rgb.red   = 255;
    	MaskColor[i].rgb.green = 255;
    	MaskColor[i].rgb.blue  = 255;

    	RGBtoCMYK(0,0,	0,	&MaskColor[i].cmyk);
    }
}

Example #2

static long RGB2Pixel_32(LPFRAME lpFrame, LPRGB lpFullRGB)

	long color;

	RGBtoCMYK( lpFullRGB->red, lpFullRGB->green, lpFullRGB->blue, &cmyk);

Example #3

	LPRGB   lpRGBPixel, 
	LPTR    lpDst,

Example #4
