在OpenCV图片（cv::Mat格式）输出汉字

static void putTextZH(const cv::Mat &inMat, const QString text, const cv::Point wordCenter, int inWordSize, const cv::Scalar inColor)
{

switch (inMat.type())

}
QColor drawColor(inColor[0], inColor[1], inColor[2]);//调用时，inColor使用CV_RGB(0, 0, 255)格式颜色
QPainter painter(&image);
QPen pen = QPen(drawColor, inWordSize);

painter.setPen(pen);
