void cv::resize(

InputArray src,

OutputArray dst,

Size dsize,

double fx=0,

double fy=0,

int interpolation=INTER_LINEAR

下面是代码部分：

void Widget::RiseUpBtn(){    cv::resize(srcImage,dstImage,cv::Size(srcImage.cols*4,srcImage.rows*4));    img = QImage((const unsigned char*)(dstImage.data),dstImage.cols,dstImage.rows,dstImage.cols*dstImage.channels(),  QImage::Format_RGB888);    ui->label_2->setPixmap(QPixmap::fromImage(img));}void Widget::RiseDownBtn(){    cv::resize(srcImage,dstImage,cv::Size(srcImage.cols/4,srcImage.rows/4));    img = QImage((const unsigned char*)(dstImage.data),dstImage.cols,dstImage.rows,dstImage.cols*dstImage.channels(),  QImage::Format_RGB888);    ui->label_2->setPixmap(QPixmap::fromImage(img));}
