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.
