A thumbnailing library for Go.

Written in Go

Earlier versions of this project were vendored into `webdir`.

- Supports jpeg / png / gif files (internally) and video files (requires `ffmpeg` in `$PATH`)
- LRU cache of recent thumbnails for performance
- Scaling algorithms: Nearest-neighbour or bilinear
- Aspect ratio preserving (fit outside with image crop; fit inside with transparent background; fit inside with dimension reduction)
- Output formats: JPG (internal) or transparent PNG (via `go-imagequant`)

A standalone binary `mkthumb` is provided as a sample utility.
