immeta, an image metadata inspection library in Rust

Documentation

immeta is an image metadata processing library. It allows you to inspect metadata, that is, image dimensions, color information, etc. of various image formats.

Currently the following image formats are supported:

JPEG
PNG 1.2
GIF (87a and 89a)
WEBP

Support for more will come in future versions.

Important note: this library is not intended to load actual image contents, i.e. the pixel data. If you need this functionality, consider using other libraries like image.

Usage

Just add a dependency in your Cargo.toml:

[dependencies]
immeta = "0.3"

You can see an example on how to use it in tests/test.rs.
