悲惨记忆。。QImage之 pixel() && setPixel()参数不要给反了。。。

1 QImage repairImg(width, height, QImage::Format_Mono);
2     for (int row = 0; row < height; row++)
3     {
4 //        uchar* ucRow = maskImg.scanLine(y);
5         for (int col = 0; col < width; col++)
6         {
7             repairImg.setPixel(col, row, (qRed(maskImg.pixel(col, row)) == 255 ? 1 : 0));
8         }
9     }
