Преобразуване на QPixmap до QByteArray
Това е един от начините за преобразуване на "QPixmap":http://doc.qt.nokia.com/latest/qpixmap.html до "QByteArray":http://doc.qt.nokia.com/latest/qbytearray.html.
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.
