psliwa / image-optimizer Goto Github PK

Hello!
I am trying to use this package with Laravel 5.6 and I can not install it with composer because of Symfony package version. There is a conflict between Laravel deps (which uses symfony/process 4.* for example) and image-optimizer (which can only use 3.* version).
I guess there are no any changes that can break the package so may be you can just safely add ~4.0 to your deps?

I am facing Optimizer img not found an error please suggest me anything.

Hi,

Why is the php-xml or (php-dom which is an alias for php-xml) required and installed in the Vagrantfile?

I ran the following command on the server:
sudo apt-get install optipng pngquant pngcrush gifsicle jpegoptim
I ran the example as stated with the ignore_errors flag set to false but I keep getting command not found.

Hi I have a wep page named teknocops.com its about technology news in google page speed test it takes 22/100 and all of errors about optimizeing images. I want to setup this to optimze my images but i dont know how can i setup i have realy poor knowledge about composers and other things if you want to help me just mail me [email protected] or skype mahirozdin_1

When you have installed only jpegoptim on your system there are no ability to optimize your images due to wrong choose algorithm.
In documentation you said: "first of two optimizations will be executed: jpegtran or jpegoptim", but in the code:

$this->optimizers['jpeg'] = $this->optimizers['jpg'] = new ChainOptimizer(array(
            $this->unwrap($this->optimizers['jpegtran']),
            $this->unwrap($this->optimizers['jpegoptim']),
        ), true);

There are new instance of ChainOptimizer with $executeFirst=true and when it optimize (with my comments)

public function optimize($filepath)
    {
        foreach($this->optimizers as $optimizer) { // get first optimizer (jpegtran) which wasn't installed
            $optimizer->optimize($filepath); // try to optimize image with it

            if($this->executeFirst) break; // break due to $this->executeFirst = true
        }
    }

And we have no chance to change the order of optimizers.
I can send a pull request for you, but which decision i have to choose: allow user to set up optimizers by hands or check optimizer availability in OS

Hello,
I need to do some image optimizations for a project and this library seems to be suited for this purpose but I wonder if it's still maintained since the last commit date one year ago.

Dear sir,

I installed all the needed libraries on Centos 6.
If i open the file OptimizersTest.php, i get a blank screen, no errors, but the size of images in folder Resources are not changed.

And than i am lost how to use the image-optimizer.
This will give the error:
Fatal error: Class 'ImageOptimizer\OptimizerFactory'

`<?php
namespace ImageOptimizer;

use ImageOptimizer\Exception\Exception;
error_reporting(E_ALL);
ini_set('display_errors', 1);
require_once 'PHPUnit/Autoload.php';
$factory = new \ImageOptimizer\OptimizerFactory();
$optimizer = $factory->get();
$filepath = 'Resources/sample.jpg';
$optimizer->optimize($filepath);
?>`

Help would be appreciated.

Kind regards,

Steven

Hello there! I recently started using your library, and at first I was quite surprise to have my images not being optimized as I expected and nothing showed up in my command (I passes a \Symfony\Component\Console\Logger\ConsoleLogger instance to \ImageOptimizer\OptimizerFactory as a second argument).

Then I digged into the code and realized that you transform every Exception being thrown into a Logger::notice(). Which only shows up if you have at least the --verbose/-v flag. Then I got some output stating that one of my option was wrong and I could fix it.

However, as these are errors (Exceptions), I think the intuitive/expected behavior would be to display them even without verbose, which is the case when using Logger::error().

What do you think ? Any specific reason why you used notice instead from the get go ?

I am trying to install in laravel 5.7 but its showing psr/log error and not supporting latest psr/log package.

Your requirements could not be resolved to an installable set of packages.

  Problem 1
    - Installation request for ps/image-optimizer ^1.2 -> satisfiable by ps/imag   e-optimizer[1.2.0].
    - Conclusion: remove psr/log 1.1.0
    - Conclusion: don't install psr/log 1.1.0
    - ps/image-optimizer 1.2.0 requires psr/log 1.0.* -> satisfiable by psr/log[1.0.0, 1.0.1, 1.0.2].

    - Installation request for psr/log (locked at 1.1.0) -> satisfiable by psr/log[1.1.0].


Installation failed, reverting ./composer.json to its original content.

Right now the namespace of this package is ImageOptimizer. Changes are low, but it's possible that this namespace could conflict with the namespaces used in the projects it is installed upon.

To lower these changes a very high percentage of packages add the vendor name to the namespace. In you case you base namespace would be Psliwa\ImageOptimizer.

If you would use psr-4 autoloading instead of the deprecated psr-0 all sources could reside in the src directly.

Obviously renaming the base namespace is a breaking change, so you would have to tag a new major version. In my opinion this is worth it.

If you want I could quickly a whip up a PR that makes the necessary changes.

Hi,

Do I have to own libraries (pngquant...) on my server when I want to use your lirbary, or do you included it into your library?

Thanks.

I am try to optimize the jpg image with below code but its not compressing. I tried with direct putty command with -m40 and its working but with this package i think its not taking -m40 in command.

$factory = new \ImageOptimizer\OptimizerFactory(array(
                                'ignore_errors' => false,
                                'jpegoptim_options' => array('-m40', '--strip-all', '--all-progressive')
                            ));
$optimizer = $factory->get();
$status = $optimizer->optimize($targetFile);

jpegoptim version
jpegoptim v1.4.6 x86_64-redhat-linux-gnu

Fatal error: Class 'Symfony\Component\Process\ExecutableFinder' not found in /opt/lampp/htdocs/test/image-optimizer/src/ImageOptimizer/OptimizerFactory.php on line 25

I think this class doesn`t exist or using wrong path,

also OptimizerFactory class using multiple classes inside single namespace

jpg image is not replaced, new generated image is saved with .jpg extension along with given file name. Ex: (imgone.jpg -> imgone.jpg.jpg)

get "Command not found" error when use open_basedir restriction.

cannot use is_executable when open_basedir path defined and executable optimizer outside of that path.

Is there a way to extend and write custom optimizer to support other command line utility tools?

I get this error:

The Symfony\Component\OptionsResolver\OptionsResolver::setOptional method is deprecated since version 2.6 and will be removed in 3.0. Use the setDefined() method instead.

This can also occur to optipng, but it is smart enough to skip the process if the output is larger than the input.

Apparently pngquant also has an option for this via --skip-if-larger, but it is not passed in the defaults in the OptimizerFactory.

Would it be possible to enable this option by default? I can enable it myself, of course, but it would be a more sane default that would improve usage for everyone 😄 .

When optimizing an image, my CPU usage skyrockets to 100% (I'm using DigitalOcean's $5/mo plan).

Is this normal? Is there anything I can do to lower the usage other than upgrading my server?

What if I need to optimize uploaded images from 100 users at the same time?

My code is bellow (sample.php)

<?php
error_reporting(E_ALL);
ini_set('display_errors', 1);

require_once 'vendor/autoload.php';

$factory = new \ImageOptimizer\OptimizerFactory(array('ignore_errors' => false));

$optimizer = $factory->get();

$filepath = __DIR__."/test.jpg";

$optimizer->optimize($filepath);
?>

but it appear error

Fatal error: Uncaught ImageOptimizer\Exception\Exception: All optimizers failed to optimize the file: /var/www/html/opt/test.jpg in /var/www/html/opt/vendor/ps/image-optimizer/src/ImageOptimizer/ChainOptimizer.php:40

what happen??

Hi there,

just tried to update the package to your last release, which is 1.2.2. But composer update failed with the following message:

  Problem 1
    - The requested package ps/image-optimizer ~1.2.2 exists as ps/image-optimizer[1.0.0, 1.0.1, 1.0.2, 1.0.3, 1.0.4, 1.0.5, 1.0.6, 1.1.0, 1.1.1, 1.1.2, 1.1.3, 1.2.0, 1.2.1, dev-master] but these are rejected by your constraint.

I quick check at https://packagist.org/packages/ps/image-optimizer revealed, that the 1.2.2 release is missing?!

Could you please check this?

Thanks

I'm having the following issue on ubuntu (using version 1.0.6):

Running the exact same command without quotes from the command line works fine:

I'm running it like this just to test:

$full_path = '/home/koichirose/public_html/dev/system/../assets/images/news/test_image.jpg';
$factory = new \ImageOptimizer\OptimizerFactory(array('ignore_errors' => false));
$optimizer = $factory->get();
$optimizer->optimize($full_path);

Your library is very good and useful in png images.
but about jpg images tinypng.com make images very optimizer than this library!
is therer any way to have better optimization for jpg?? (like installing an other jpg optimzer )

i cant use it . want to help

In some cases we may not want to overwrite the original. Maybe an option could be to change the filename or add a suffix for it?

Hi admin,
I using php phalcon, I had been include this image-optimizer but Error
"Symfony class not found"....

Please help me

Right now, when installing the package on a production server, the tests get installed as well. This can be avoided by adding a .gitattributes file. In this file you can specify which files should not be used when installing the package somewhere.

Here's an example of such a file: https://github.com/spatie/laravel-backup/blob/master/.gitattributes

There are no downsides of adding such a file, so I highly recommend adding one to this package.

Currently it's very hard to find out what has changed between releases.

This could be solved by added a changelog. Here's an example of such a changelog. Here some more info about changelogs in general: http://keepachangelog.com/en/1.0.0/

Anyways, it just a suggestion, feel free to ignore it.

you are deletıng my need post then help me to use it. [email protected] teamvier just takes 2 mınutes.

Shouldn't

$commandArgs = 0 === count($args) ? '' : ' '.implode(' ', array_map('escapeshellarg', $args));

in Command.php be

$commandArgs = 0 === count($args) ? '' : ' '.implode(' ', array_map($escapeShellCmd, $args));

Hi I receive this messsage

Hello, can you help me? I installed your library using composer, installed all libraries (optipng, etc.), wrote
$factory = new \ImageOptimizer\OptimizerFactory(array('ignore_errors' => false));
But file is not optimized.
I tried:
$filepath = 'Upload/'.$data['name'];
try {
$optimizer->optimize($filepath);
} catch (CommandNotFound $e) {
echo "string";
}

But 'echo "string";' doesn't appear on my screen.

This seems like a no brainer given it is already a dependency.

It would add the ability to have timeouts, analyse exit codes, etc.

If this is something you're keen on I'd be happy to have a stab at a PR.

Hi, this package seems awesome.

However, when looking at the source code I see many inconsistencies in how to code is formatted.

Here's a friendly suggestion: use a service like Style CI to automatically make and keep the code style consistent. I've used the service on many packages before and quite happy with it.

If you're happy with how the code is now feel free to ignore this issue.

What is The Problem ?!

I used this package few month ago, all was going ok. but today, get error

ErrorException in Command.php line 38:
Undefined variable: outputLines

line 38 is: exec($command, $outputLines, $result);

help me check, I don't know why, I don't edit or do anything in my server.

my version is 1.1, using pngquant to optimized

Right now a contributor has no way of knowing how you like changes to be PR'ed. Adding a file with contributor guidelines would help that.

Here's the one we use for our packages. https://github.com/spatie/skeleton-php/blob/master/CONTRIBUTING.md

Not saying you should use that one, but it could serve as a nice starting point for you.

Hi,

just wanted to let you know that I've integration your package in one of my own:

https://docs.spatie.be/image/v1/image-manipulations/optimizing-images

Thank you for having created image-optimizer! 👍

Do you have in your roadmap to integrate SVGO library to optimize svg images?
https://github.com/svg/svgo
Also what about pdf optimization?
Thanks :)

Hi All,

I have followed the steps, installed all the correct libraries and tried in both Windows and Linux. I get no errors at all, it just doesn't optimise my images. At first I thought it wasn't finding my images but when I changed the location a non-existent image it then threw an error leaving me at a loss as to why it wouldn't optimise my images.

`require_once (DIR."/vendor/autoload.php");

$factory = new \ImageOptimizer\OptimizerFactory(array('ignore_errors' => false));
$optimizer = $factory->get();
$images = glob("images///*.{jpg,png,gif}", GLOB_BRACE);
foreach ($images as $image) {
$oldFileSize = filesize($image);
$optimizer->optimize($image);
print("Optimised: " . $image . " Saved: ".number_format((1 - $oldFileSize / filesize($image)),2) ."% \n");
}`

Can anyone suggest as to where I may be going wrong (Installed via composer, latest version).

Any help appreciated, it seems like a great library and if I can work out why I'll post my solution here.

Thanks,
Dom

Hi, I followed the example, and nothing is happening. Libraries are loaded OK, but images (jpg for example) are not reducing its size.
Is there a way to check if I am doing everything right?
My code is:

error_reporting(E_ALL);
ini_set('display_errors', 1);
$loader = require DIR.'/../vendor/autoload.php';
$loader->addPsr4('ImageOptimizer\', DIR.'/ImageOptimizer');
$factory = new \ImageOptimizer\OptimizerFactory(array('ignore_errors' => false));
$optimizer = $factory->get();
$filepath = 'imagen.jpg';
$optimizer->optimize($filepath);
//optimized file overwrites original one

Then, I get the following error: "Fatal error: Uncaught exception 'ImageOptimizer\Exception\Exception' with message 'All optimizers failed to optimize the file: imagen.jpg' "

Thanks in advance!

I noticed that the optimized images still have the CREATOR and QUALITY comments. "CREATOR: gd-jpeg v1.0 (using IJG JPEG v62), quality = 75"

Is there a way these can also be removed?

Hi, thanks for the awesome library. I'm using jpegoptim. i want to specify the quality of the image when optimizing. Currently arguments are set to --strip-all, --all-progressive. is there a way I can specify the arguments for jpegoptim?

Thanks

I'm using Image-Optimizer within an own addon and everytime i try to optimize an transparent png it gets a black background. Do you have an Idea?

Trying to include this with latest Laravel 5.2 and got the following error. I think it's because Laravel already ships with Symfony Process 3.0 and this package requires ~2.0.

How can I set my options such that PNG images only use only optipng and not pngquant?

Here is the exception I receive with running optimize:

ImageOptimizer\Exception\Exception: Command failed, return code: 1, command: C:^\Program Files^\pngquant^\pngquant.EXE "--force" "--ext=.png" "--" "F:\laragon\www\demo\images\uploads\ec498dcfc950e8df339c81ec73ac70e2b46f87b2.png" in F:\laragon\www\demo\vendor\ps\image-optimizer\src\ImageOptimizer\Command.php

. On the other hand, if I run pngquant "--force" "--ext=.png" "--" "F:\laragon\www\demo\images\uploads\43d67cba7a951378485882e5b515c825943f7d0a.png"directly in shell, it works fine.
