Overview

Package image provides an image store and resizer. It depends on convert (from imagemagick). Uploaded files are stored in original, but not served via HTTP.

store := image.Store{
    CacheDir: filepath.Join(os.Getenv("CACHE_DIRECTORY"), "imagedir"),
    Dir:      filepath.Join(os.Getenv("STATE_DIRECTORY"), "imagedir"),
    MaxSides: []int{300, 600, 1200},
}

router.Handler(http.MethodGet, "/images/*filepath", http.StripPrefix("/images", store))
