Mongodb C++ API insert binary (images)

Question

I looked around and couldn't find a working example for mongocxx binary insert.

I want to insert images to the MongoDB through mongocxx. I can insert except binary.

I am seeking a working example for binary (image) insert to MongoDB through mongocxx. I am using OpenCV.

I'll show you mine if you show me yours - well, maybe. The point is have a go and then ask a specific problem — UKMonkey

Once you've manage to store your image in a buffer (for instance in std::vector), you need to use

bsoncxx::types::b_binary img {bsoncxx::binary_sub_type::k_binary, 
                              uint32_t(raw.size()),
                              raw.data()};`

Then you can pass the img object via the common document{} << ... syntax.
