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.

On a Kitty terminal:
On a Mac with iTerm:
Using half blocks (Kitty protocol and tmux
do not get along):
Ctrl-C was pressed to stop the GIFs.
When viu
receives only one file and it is GIF, it will be displayed over and over until Ctrl-C is
pressed. However, when couple of files are up for display the GIF will be displayed only once.
iTerm can handle GIFs by itself with better performance, but configuration through --once
and --frame-rate
will have no effect there.
If no flags are supplied to viu
it will try to get the size of the terminal where it was invoked.
If it succeeds it will fit the image and preserve the aspect ratio. The aspect ratio will be changed
only if both options -w and -h are used together.
View images right from the terminal.
Usage: viu [OPTIONS] [file]...
Arguments:
[file]... The images to be displayed. Set to - for standard input.
Options:
-w, --width <width>
Resize the image to a provided width
-h, --height <height>
Resize the image to a provided height
-x <x>
X offset [default: 0]
-y <y>
Y offset [default: 0]
-a, --absolute-offset
Make the x and y offset be relative to the top left terminal corner. If not set, they are relative to the cursor's position.
-r, --recursive
Recurse down directories if passed one
-b, --blocks
Force block output
-n, --name
Output the name of the file before displaying
-t, --transparent
Display transparent images with transparent background
-f, --frame-rate <frames-per-second>
Play the gif at a given frame rate
-1, --once
Loop only once through the gif
-s, --static
Show only the first frame of the gif
-H, --help
Print help information
-V, --version
Print version information
