## What it is
A pure Go library that finds good image crops for arbitrary crop sizes, based on Jonas Wagner's smartcrop.js. It includes a simple CLI application for cropping images from the command line.

## Use cases
- smart crop images to arbitrary aspect ratios
- generate thumbnails that keep the subject centered
- crop photos automatically for different screen sizes
- batch crop images from the command line
- find the most interesting region of an image to crop

## When to choose
- you need content-aware cropping in a Go application
- you want a dependency-light, pure Go image cropping solution
- you need a CLI tool to crop images to specific dimensions

## When to avoid
- you need face detection or deep-learning-based cropping
- you work primarily in JavaScript (use smartcrop.js instead)
- you need the library to also resize or encode images for you

## Facets
- artifact type: library
- maturity: maintenance
- function: image-processing
- domain: image-processing, computer-vision
- platform: go, cross-platform, cli
- tags: smart-cropping, content-aware-crop, thumbnailing, pure-go
