This package wraps the core functionality of libvips image processing library by exposing all image operations on first-class types in Go.

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

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.

• libvips 8+ (8.8.1+ recommended for GIF, PDF, SVG, HEIC support)
• C compatible compiler such as gcc 4.6+ or clang 3.0+
• Go 1.11+

go get -u github.com/wix-playground/govips/vips

image, err := NewImageFromFile("image.jpg")
if err != nil {
	return nil, err
}
defer image.Close()

// Resize an image with padding
return vips.Transform().
	PadStrategy(vips.ExtendBlack).
	Resize(1200, 1200).
	ApplyAndExport(image)

In short, feel free to file issues or send along pull requests. See this guide on contributing for more information.

Thank you to John Cupitt for maintaining libvips and providing feedback on vips.
