Overview

This repository provides EXIF and image support that transcends any one format but lives close to the implementation.

Tree Index

Filesystem paths or trees can be loaded in an index. Files that have a given tag are grouped together. Values of all tags or specific tags can also be searched case-insensitively.

This operation will identify and parse most any format that supports EXIF.

See the Go Reference link for usage examples.

Tools

ee_filesystem_indexer

This will allow you to browse through the tags of all loaded images.
