----

A small command-line application to view images from the terminal written in Rust. It is basically the front-end of viuer. It uses either iTerm or Kitty graphics protocol, if supported. If not, lower half blocks (▄ or \u2584) are displayed instead.

Based on the value of $TERM, viuer decides which protocol to use. For half blocks, $COLORTERM is inspected. If it contains either truecolor or 24bit, truecolor (16 million colors) will be used. If not, it will fallback to using only ansi256. A nice explanation can be found in this [gist](https://gist.github.com/XVilka/8346728).
