|
A thumbnailing library for Go.

- Supports jpeg / png / gif / bmp / webp files (internally)
|
|
- Supports video files (requires `ffmpeg` in `$PATH`)
|
|
- Optional LRU cache of recent thumbnails for performance
|
|
- Sampling algorithms: Nearest-neighbour, Bilinear (fast), Bilinear (accurate), Bicubic (Catmull-Rom)
|
|
- Scaling algorithms: Fit inside, Fit outside, Stretch
|
|
- Output formats: JPG, PNG, Quantised/lossy PNG (via `go-imagequant` if CGO is available), BMP
|
|
|
|
A standalone binary `mkthumb` is provided as a sample utility.
