Adding custom metadata to jpeg files

I am working on an image processing project (C ++), and after processing is complete, I need to write my own metadata in a jpeg file. How can i do this? Is there a library available for this?

If you are talking about EXIF ​​metadata, you can look at exiv2 , which is a C ++ library for processing EXIF ​​metadata. There is a second lib called libexif and is written in C.

Exiv2 has examples on its website, and the API is well documented.

UPDATE: if you want to add your own metadata, you can use the MakerNoteor tag Comment.

Exif Standard: PDF . 4.6.5. EXIF ​​IFD 7, , .
