wformat is a command line utility to organize collections of wallpapers
For now, it can only reformat images into proper sizes(for dualmonitors too)
Soon it will feature organization through renaming and the ability to search for duplicates of images
Create a merged image:
wformat merge [IMAGE_ONE] [IMAGE_TWO]
The default expected dual monitor screen is actually 1920x1200. Change that using options
wformat merge --widthone=1600 --heightone=1200 --widthtwo=800 --heighttwo=600 [IMAGE_ONE] [IMAGE_TWO]
Or give the merge your own output filename
wformat merge --title="turtles.jpg" [IMAGE_ONE] [IMAGE_TWO]
Create a scaled image:
wformat scale [IMAGE_ONE]
The default expected monitor screen is actually 1920x1200. Change that using options
wformat scale --width=1600 --height=1200 [IMAGE]
Or give the scaled result your own output filename
wformat scale --title="turtles.jpg" [IMAGE]
