how to generate image from raw pixel data

hi
how to generate image from raw pixel data .
at present i am using this

            int pixel=0;
            for (int y = 0; y < height; y++)
            {
               for (int x = 0; x < width; x++)
               {

                    QRgb value = qRgb((Auto_image_RGBdata[pixel] >> 22 & 0x000000ff),(Auto_image_RGBdata[pixel] >> 12 & 0x000000ff), (Auto_image_RGBdata[pixel]>>2  & 0x000000ff));
                    pixel+=1;
                    img.setPixel(x,y,value);
               }
            }
            ui->port_2->setPixmap(QPixmap::fromImage(img.scaled(781,351,Qt::IgnoreAspectRatio,Qt::SmoothTransformation)));
            ui->port_2->setScaledContents(true);

is there any faster method than this?
