Преобразуване на QPixmap до QByteArray

Това е един от начините за преобразуване на QPixmap до QByteArray.

Удобен е в случайте, когато искате да съхранявате QPixmap в база от данни и т.н.

QPixmap pixmap; QByteArray bArray; QBuffer buffer( &bArray ); buffer.open( QIODevice::WriteOnly ); pixmap.save( &buffer, "PNG" );

Сега променливата bArray съдържа изображението като последователност от байтове.
