彩色图像：

//截取电脑屏幕图像
	QPixmap pixMap = QPixmap::grabWindow(QApplication::desktop()->winId());
	pixMap.save("D:/A.png", "png");		
	HalconCpp::HObject ho_ImageR, ho_ImageG, ho_ImageB;
	QImage qimg = pixMap.toImage();
	int width = qimg.width();
	int height = qimg.height();

	unsigned char* pDataR = nullptr, *pDataG = nullptr, *pDataB = nullptr;
	pDataR = (unsigned char*)malloc(width*height * sizeof(unsigned char));
	pDataG = (unsigned char*)malloc(width*height * sizeof(unsigned char));
	pDataB = (unsigned char*)malloc(width*height * sizeof(unsigned char));
	memset(pDataR, 0, width * height * sizeof(unsigned char));
	memset(pDataG, 0, width * height * sizeof(unsigned char));
	memset(pDataB, 0, width * height * sizeof(unsigned char));
	for (size_t i = 0; i < height; i++)
	{
		uchar* pScr = qimg.scanLine(i);
		for (size_t j = 0; j < width; j++)
