qt调zint把文本转化成条码并显示

需求是要把一串数字转化成条码，显示在界面上供打印机打印。

过程是使用zint库转化文本为rgb的buffer,然后把rgb转换成qt的QPixmap,在界面上显示，

如果是MFC的话，原理相通，有rgb数据显示都好办。

QPixmap Bitmap2Pixmap(unsigned char *bitmap, int width, int height)
{
    QImage img(bitmap, width, height, QImage::Format_RGB888);
    QPixmap ret;
    ret.convertFromImage(img);
    return ret;
}



    struct zint_symbol *m_symbol;
    m_symbol = ZBarcode_Create();
    if (m_symbol == NULL)
    {
        QMessageBox::warning(this, "test", "ZBarcode_Create create failed!");
        return;
    }
    else
    {
        m_symbol->symbology = BARCODE_CODE128;
        m_symbol->scale = 2;
    }

    ZBarcode_Encode_and_Buffer(m_symbol, (unsigned char *)inputStr.toLocal8Bit().data(), deviceId.size(), 0);
    QPixmap pixmap = Bitmap2Pixmap((unsigned char *)m_symbol->bitmap, m_symbol->bitmap_width, m_symbol->bitmap_height);
    ui->codeLabel->setPixmap(pixmap);
    ZBarcode_Delete(m_symbol);
