Usage β
Singe conversion
gowall convert path/to/img.png -t <theme-name>
Notes ποΈ :
path/to/img.png does not have to be an absolute path. You can use a relative path with the ~ ex. ~/Pictures/img.png
- you can find the list of all the themes via
gowall list check number 6. as well
-
Batch conversion
gowall convert -b path/img.png,path/im2.png -t <theme-name-lowercase>
β οΈ Do not leave any white spaces between the comma , , do it like this : path/img.png,path/im2.png
-
Invert colors
gowall invert path/to/img.png
You can also batch invert colors with :
gowall invert -b path/img.png,path/img2.png
-
Convert a whole Directory
Use the # delimiter to convert every image file under that directory
gowall convert ~/Pictures/# -t catppuccin
gowall invert ~/Pictures/test/#
Notes ποΈ : Only png jpeg jpg webp images will be converted any other directory or other file will be ignored
-
List all theme names
gowall list
Notes ποΈ: You can view the colors of a theme by using the -t flag
Example:
gowall list -t catppuccin
You can also open up a hex preview app in your default browser via the -p flag
Example : gowall list -pt catppuccin
-
Image previewing
Image previewing is available for single image processing and is ON by default
Examples : gowall convert ~/Pictures/img.png and gowall invert ~/Pictures/img.png
You can disable it by adding the following inside your ~/.config/gowall/config.yml
EnableImagePreviewing: false
-
Pallete extraction ( Like pywal )
You can extract the color pallete of an image as shown below :
gowall extract /path/to/img.png -c 6
The -c flag specifies how many hex color codes to return ( Personally i recommend between 6-16 with 6-7 being my go to).
This will print the color codes to the terminal. In order for you to view all the colors of the hex codes at once you can use the -p flag.
gowall extract /path/to/img.png -pc 6
That will open a hex code previwer in your default web browser
-
Wallpaper of the Day
View beautiful wallpapers that reset daily
gowall -w
You can see an example here
-
Changing formats
Change the format of an image, the available formats are png jpeg jpg webp
gowall convert ~/Pictures/img.webp -f png
-
Adding a border
Using the draw command you can draw a border and specify the color, thickness etc...
The below draws a border 5px thick with the color #5D3FD3
gowall draw ~/Pictures/img.png -c #5D3FD3 -b 5
