QImage image1 = QImage((uchar*)pFrame1->imageData, pFrame1->width, pFrame1->height, QImage::Format_RGB888).rgbSwapped();
QImage result1 = image1.scaled(ui->NO1->height(),ui->NO1->width(),Qt::IgnoreAspectRatio, Qt::SmoothTransformation);
ui->NO1->setPixmap(QPixmap::fromImage(result1));
里面的QImage::Format_RGB888.rgbSwapped()
Qt::IgnoreAspectRatio, Qt::SmoothTransformation
具体什么意思 详细一点 谢谢
