Project history

tev is an open-source, cross-platform image viewer developed around accurate HDR display and color management. Its scope grew to include many still-image and raw formats, metadata and auxiliary channels, image-analysis tools, command-line operation, and remote control over a TCP protocol.

The project changed licensing after its 1.30 series: the official README states that releases through version 1.30 used the BSD 3-Clause license, while current development uses GPLv3.

Adoption history

The project is distributed for macOS, Windows, and Linux and documents installation through Homebrew, AUR, Flatpak, Scoop, WinGet, and Nix.

How it is used

Users open or drag in images, select reference images for comparison, inspect channels and layers, calculate error metrics, adjust exposure and tone mapping, or invoke tev with image paths from the command line. Renderers can create and update images through tev's TCP protocol.

Why package nerds care

tev is useful in rendering, graphics, photography, and visual-effects workflows because it handles high-dynamic-range and multilayer images, performs image comparisons, and exposes a network protocol that renderers and other tools can use to update images live.

Timeline

• Through version 1.30: tev releases were available under the BSD 3-Clause license.
• After version 1.30: the project adopted GPLv3 licensing.
• Current generation: tev supports graphical, command-line, and network-controlled workflows across macOS, Windows, and Linux.

Related projects

• The official README names pbrt version 4 as an example renderer that can use tev as a network-controlled display and documents C++, Python, and Rust protocol implementations.
