imagemeta's Introduction

Imagemeta

Image Metadata (Exif and XMP) extraction for JPEG, HEIC, AVIF, TIFF, and Camera Raw in golang. Imagetype identifcation. Zero allocation Perceptual Image Hash. Goal is features that are precise and performance oriented for working with images.

Documentation

See Documentation for more information.

Example Usage

Example usage:

    package main

    import (
    	"fmt"
    	"os"

    	"github.com/evanoberholster/imagemeta"
    )

	f, err := os.Open("image.jpg")
	if err != nil {
		panic(err)
	}
	defer f.Close()

	e, err := imagemeta.Decode(f)
	if err != nil {
		panic(err)
	}
	fmt.Println(e)

Imagehash

Zero allocation PerceptualHash algorithm (64Bit and 256Bit) github.com/evanoberholster/imagemeta/imagehash. Adapted from https://github.com/corona10/goimagehash. Image will need to be resized to 64x64 prior to image hashing.
