## What it is
Oculante is a fast, hardware-accelerated, open-source image viewer with basic nondestructive editing and image analysis tools, supporting a wide range of formats including DDS, HDR, PSD, EXR, and TIFF. It is written in Rust and runs on Windows, macOS, Linux, FreeBSD, and NetBSD.

## Use cases
