Opal

Opal is a tool to change images color palette.

It supports png, jpeg, jpg, bmp, ico and gif (with no animations yet).

Installing

Clone the repository:

git clone https://github.com/sixels/opal.git && cd opal

Setup a rust environment then run:

cargo install --path .

Usage

For now, Opal has only two positional arguments, the filename and the color scheme (it doesn't support multiple images at the same time). You can run it as follow:

opal path/to/image (nord|gruvbox|oceanic|dracula)

Preview

Original Image	Dracula	Gruvbox	Nord

All images were compressed after being generated.

TODO

• Refactoring
• Better CLI interface
• Add more color schemes
• Support custom color schemes
• Progress bar
