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:
