bimg

Go library for blazing fast image processing based on libvips using C bindings.

libvips is typically 4x faster than using the quickest ImageMagick and GraphicsMagick settings, and even 8x faster with JPEG format. It support JPEG, PNG, WEBP, TIFF and Magick image formats.

bimg was heavily inspired in sharp, a great node.js package for image processing build by Lovell Fuller.

Work in progress

Prerequisites

• libvips v7.40.0+ (7.42.0+ recommended)
• C++11 compatible compiler such as gcc 4.6+ or clang 3.0+

Installation

go get gopkg.in/h2non/bimg.v0

Requires Go 1.3+

API

import (
  "fmt"
  "os"
  "gopkg.in/h2non/bimg"
)

options := bimg.Options{
    Width:        800,
    Height:       600,
    Crop:         true,
    Quality:      95,
}

newImage, err := bimg.Resize(image, options)
if err != nil {
  fmt.Fprintln(os.Stderr, err)
}
