Crunch takes an image and applies a transformation to it. But what if you want to do two transformations? Or transform more than one image at a time?
Pipelines!
The main value of Crunch is reproducible image processing, as defined by a pipeline toml file.
Basic CLI usage:
```shell Command line asset manipulation, set up a pipeline once and run it against all of your files

You can simply download this repository and run cargo build --release to get a binary for your system. Using --release mode
is required in all situations, as the time taken to run a command with the debug build is several orders of magnitude higher.
If you use the .local/bin pattern for non-sudo userspace programs, you can use the included build script to simplify things. Otherwise,
follow the below instructions:
Simple Script
- Clone this repository
- Run sh source-install.sh
Manual
- Clone this repository
- Run cargo build --release
- Optionally, strip the binary
- Copy target/release/crunch to a folder located in your $PATH
