QT 图片与base64互转

QT 图片与base64互转

1、图片转base64

    QImage image(":/image/wrong");
    QByteArray ba;
    QBuffer buf(&ba);
    image.save(&buf, "png");
    qDebug() << ba.toBase64();
    buf.close();

2、base64转图片

        QString p_b;//base64字符串
        QPixmap image;
        image.loadFromData(QByteArray::fromBase64(p_b.toLocal8Bit()));
