README

        # imgdiff

Faster than [the fastest in the world pixel-by-pixel image difference tool](https://github.com/dmtrKovalenko/odiff).

## Why?

imgdiff isn't as fast as a tool like this should be and I'm not proud of it, but it is 3X faster than

[the fastest in the world pixel-by-pixel image difference tool](https://github.com/dmtrKovalenko/odiff),

so maybe you'll find it useful.

## Features

It can do everything [odiff](https://github.com/dmtrKovalenko/odiff) can. Faster.

## Benchmarks

I've tested it on Linux, Intel(R) Core(TM) i7-4700HQ CPU @ 2.40GHz, 8 cores.

## Usage

```

Usage: imgdiff [--threshold THRESHOLD] [--diff-image] [--fail-on-layout] BASE COMPARE OUTPUT

Positional arguments:

  BASE                   Base image.

  COMPARE                Image to compare with.

  OUTPUT                 Output image path.

Options:

  --threshold THRESHOLD, -t THRESHOLD

                         Color difference threshold (from 0 to 1). Less more precise. [default: 0.1]

  --diff-image           Render image to the diff output instead of transparent background. [default: false]

  --fail-on-layout       Do not compare images and produce output if images layout is different. [default: false]

  --help, -h             display this help and exit

```

## Download

You can find pre-built binaries [here](https://github.com/n7olkachev/imgdiff/releases/tag/v1.0.0).

imgdiff is written in Go, so there shouldn't be any troubles to compile it for the most of popular platforms.
