只需zint.h和zint.lib库，无需动态链接库，即可使用

生成二维码必备，使用简单。直接保存成QPixmap。 struct zint_symbol* my_symbol = ZBarcode_Create(); my_symbol->symbology = BARCODE_QRCODE; my_symbol->scale = 2; my_symbol->show_hrt = 0; ZBarcode_Encode_and_Buffer(my_symbol, (unsigned char *)m_keyString.toUtf8().data(), 0, 0); QPixmap pixmap = Bitmap2Pixmap((unsigned char *)my_symbol->bitmap, my_symbol->bitmap_width, my_symbol->bitmap_height);
