A libvips library for Go

This package wraps the core functionality of libvips image processing library by exposing all image operations on first-class types in Go. Additionally, it exposes raw access to call operations directly, for forward compatibility.

How fast is libvips? See this: Speed and Memory Use

This library was inspired primarily based on the C++ wrapper in libvips.

The intent for this is to enable developers to build extremely fast image processors in Go, which is suited well for concurrent requests.

Libvips is generally 4-8x faster than other graphics processors such as GraphicsMagick and ImageMagick.

Supported image operations

This library supports all known operations available to libvips found here:

Requirements

  • libvips 8+ (8.5.8+ recommended for GIF, PDF, SVG support)
  • C compatible compiler such as gcc 4.6+ or clang 3.0+
  • Go 1.9+

Installation

go get -u github.com/davidbyttow/govips/pkg/vips

Example usage

// Resize an image with padding
return vips.NewPipeline().
	LoadFile(inputFile).
	PadStrategy(vips.ExtendBlack).
	Resize(1200, 1200).
	OutputFile(outputFile)
