elixir_exif

ElixirExif is a library for extracting EXIF (Exchangeable Image File Format) metadata and embedded thumbnail data from JPEG and TIFF image files. It enables developers to access camera settings, geolocation, timestamps, and other photographic information stored within image files, which is essential for applications processing digital photos.

Key Features

• EXIF Tag Parsing — Extracts all standard EXIF metadata fields including camera make/model, exposure settings, GPS coordinates, and creation date.
• Thumbnail Extraction — Retrieves embedded thumbnail images (JPEG format) commonly stored within EXIF data for quick previews.
• Dual Input Support — Accepts both file paths and raw binary data as input, offering flexibility for different use cases.
• Structured Output — Returns parsed data in a structured format suitable for further processing in Elixir applications.

Philosophy

ElixirExif follows Elixir's functional programming principles, providing simple, reliable functions that return tagged tuples for clear error handling and data flow.
