Detailed Description

EXIF file format support library. This API allows to parse, read and modify EXIF data structures. It provides a low-level API which allows to manipulate EXIF tags in a generic way, and a higher-level API which provides more advanced functions such as comment editing, thumbnail extraction, etc.

In the future, vendor-proprietary exif extensions might be supported.
