NAME¶
imv - Image viewer for X11 and Wayland
DESCRIPTION¶
imv is an image viewer for X11 and Wayland, aimed at users of
tiling window managers. It supports a wide variety of image file formats,
including animated gif files. imv will automatically reload the current
image, if it is changed on disk.
In Debian the executable and the associated manpages were renamed
from imv to imvr because of a name clash.
