-----
sxiv supports the following command-line options:
-w WIDTHxHEIGHT set window width to WIDTH and height to HEIGHT
(if HEIGHT is omitted, height is also set to WIDTH)
-d scale all images to 100%, but fit large images into window
-f start in fullscreen mode
-p pixelize, i.e. turn off image anti-aliasing
-s scale all images to fit into window
-v print version information and exit
-w WIDTHxHEIGHT
set window width to WIDTH and height to HEIGHT
(if HEIGHT is omitted, height is also set to WIDTH)
-Z same as `-z 100'
-z ZOOM scale all images to current zoom level, use ZOOM at startup
Use the following keys to control sxiv:
