A cli utility that can change the color palette of an image to whatever you want.
This project was meant to be just an experiment on building a Kotlin Multiplatform CLI application, so there might be similar projects with better performances and/or results. Also, given the current state of Kotlin Native, the native builds are much slower (around 4-5x slower) than the JVM build.
Usage: main [OPTIONS] INPUT_FILE OUTPUT_FILE
Options:
-p, --palette TEXT The color palette, depends on the provider
: for "gogh" : The file name without the
extensions, file names are listed here :
https://github.com/Gogh-Co/Gogh/tree/master/themes
; for "url" : The url of a file containing
hex colors (like "#FFFFFF"); for "local" :
The local path of a file containing hex
colors (like "#FFFFFF"); for "text" : A
comma separated list of hex colors (like
"#FFFFF,#FF00FF,#FFFF00").
-P, --palette-provider [gogh|local|url|text]
The palette source name.
-c, --chroma / -C, --no-chroma Keep/do not keep the original color chroma
(colorfulness)
-l, --lightness / -L, --no-lightness
Keep/do not keep the original color
lightness
--hide-progress Hide the progress
--color-comp-alg [CIE76|CIE94|CIEDE2000]
The color comparison algorithm used to
compute new colors. CIEDE2000 is the more
efficient and CIE76 the faster. Default
value : CIEDE2000
-e, --excluded-colors TEXT Colors that will be excluded from the new
colors. Must be a comma separated list of
hex colors (like "#FFFFF,#FF00FF,#FFFF00")
-h, --help Show this message and exit
