Hi,

I would like to know are there any ways to convert jpeg to bytes and vice versa,because the ultimate aim is to receive images through C code and insert it into DB....

推荐答案

通常您收到（您没有指定接收它们的方式）图像为一堆字节。因此，不应对接收的数据进行特殊转换。另一方面，为了在数据库上存储二进制数据，你必须使用名为 BLOB 的东西，例如参见MySQL BLOB [ ^ ]（这里您可以找到示例C代码此处 [ ^ ]，查看将图像插入MySQL数据库部分）。

Usually you receive (you did not specify the way you receive them) images as bunchs of bytes. So no special tranformation on received data should be performed. On the other hand, in order to store binary data on the database then you have to use something called BLOB, see for instance MySQL BLOB[^] (here you may find sample C code here[^], check out the "Inserting images into MySQL database" section).
