How to use jpegtran with composer

PHP
1

hi all

i just installed composer on xampp

i want to use jpegtran from optimizing images

so i downloaded a library folder from github

This is their sample.php for optimizing png file

<?php
//include('./vendor/autoload.php');

$advPng = new \PHPImageOptim\Tools\Png\AdvPng();
$advPng->setBinaryPath('/usr/local/bin/advpng');

$optiPng = new \PHPImageOptim\Tools\Png\OptiPng();
$optiPng->setBinaryPath('/usr/local/bin/optipng');

$pngOut = new \PHPImageOptim\Tools\Png\PngOut();
$pngOut->setBinaryPath('/usr/local/bin/pngout');

$pngCrush = new \PHPImageOptim\Tools\Png\PngCrush();
$pngCrush->setBinaryPath('/usr/local/bin/pngcrush');

$pngQuant = new \PHPImageOptim\Tools\Png\PngQuant();
$pngQuant->setBinaryPath('/usr/local/bin/pngquant');

$optim = new \PHPImageOptim\PHPImageOptim();
$optim->setImage('./tests/image/lenna-original.png');
$optim->chainCommand($pngQuant)
    ->chainCommand($advPng)
    ->chainCommand($optiPng)
    ->chainCommand($pngCrush)
    ->chainCommand($pngOut);
$optim->optimise();
?>

But there is no vendor folder and autoload file.

so i commented that line and tried with composer

there is composer.json file

{
    "name": "bensquire/php-image-optim",
    "type": "library",
    "description": "A library to aid in image optimisation",
    "keywords": ["image", "php", "optimisation", "png", "jpg", "gif"],
    "homepage": "https://github.com/bensquire/php-image-optim",
    "license": "MIT",
    "authors": [
        {
            "name": "Ben Squire",
            "email": "b.squire@gmail.com",
            "homepage": "https://github.com/bensquire/php-image-optim"
        }
    ],
    "support": {
        "issues": "https://github.com/bensquire/php-image-optim/issues",
        "wiki": "https://github.com/bensquire/php-image-optim/wiki"
    },
    "require": {
        "php": ">=5.6.0"
    },
    "require-dev": {
        "phpunit/phpunit": "5.*"
    },
    "autoload": {
        "psr-0": {
            "PHPImageOptim": "src/"
        }
    }
}

But i get this below error

Fatal error:  Class 'PHPImageOptim\Tools\Png\AdvPng' not found in E:\xampp\htdocs\myapp\jpegtran\php-image-optim-master\php-image-optim-master\sample.php on line 4

what should i do ??

you need to install your dependencies before you can use them.

hi Dormilich

in the composer.json its written

"require": {
        "php": ">=5.6.0"
    },
    "require-dev": {
        "phpunit/phpunit": "5.*"
    },

first one means php 5.6 is required

what is second one “phpunit” ?? do i have to install it separately ??

or “phpunit” will get install with running composer ??

it’s a framework for unit tests.

you do not install dependencies, composer does. (at most you define dependencies).

I am getting this error. dont know why

you’re on Windows. the path used is for Linux/Unix.

and since you’re likely to ask, advpng, optipng, pngout, pngcrush, and pngquant are command line tools you would have to install first.
