README.md

A thumbnailing library for Go.

Written in 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), BMP

A standalone binary mkthumb is provided as a sample utility.

This package can be installed via go get: go get code.ivysaur.me/thumbnail [go-get]code.ivysaur.me/thumbnail git https://git.ivysaur.me/code.ivysaur.me/thumbnail.git[/go-get]
