Auto Smush

Recommended Posts

Module: Auto Smush

https://github.com/matjazpotocnik/AutoSmush 

Optimize/compress images.

In Automatic mode images that are uploaded can be automatically optimized. Variations of images that are created on resize/crop and admin thumbnails can also be automatically optimized. In Manual mode "Optimize image" link/button will be present. This allows manual optimization of the individual image or variation. In Bulk mode all images, all variations or both can be optimized in one click. Will process images sitewide.

Two optimization "engines" are avaialable. reShmush.it is a free (at the moment) tool that provides an online way to optimize images. This tool is based on several well-known algorithms such as pngquant, jpegoptim, optipng. Image is uploaded to the reSmush.it web server, then optimized image is downloaded. There is a 5 MB file upload limit and no limit on number of uploaded images. "Local tools" is set of executables on the server for optimizing images: optipng, pngquant, pngcrush, pngout, advpng, gifsicle, jpegoptim, jpegtran. Binaries for Windows are provided with this module in windows_binaries folder, copy them somewhere on the PATH environment variable eg. to C:\Windows.

Thanks for this - looks great, but curious if you know if they have plans to start charging ? I didn't see anything on their website (http://www.resmush.it/) to indicate the long term plans.

I don't know about plans. The service is up for quite a time, sure more over a year, but it's not clear who is owner of site. Site is created by French Tech, the collective name for all those working in the French startup market. There is also no privacy policy available, so who knows what happen with your uploaded images. There are other services with "free" plans, but with limitations, like file size (100kB) or number of images (eg. 500 per month). I actually don't like web services, because first you upload the image to your server, then upload to web service and then download it. That's why I use local tools on the server, but that come with a price, cpu & memory usage, but I can aford it, since I'm the sysdamin :-) 

Auto Smush is somehow different from other modules, since it does not add the method(s) to PageImage, thus you don't have to change your code and also you may uninstall (or disable) the module at any time without code modification in your templates.

Only started it :) Then came @matjazp and fixed a number of issues, added local tools and so on. I kinda lost interest when I made it work on my sites and do not wanted to invest more time to improve and make it ready for public. So big thanks to matjazp, and hopefully after a few iterations it will be more stable.

Great! I was looking for a module like this after https://minimize.pw/ closed the doors.

I have to test it tomorrow. I guess it works with Croppable Image 3, too, doesn’t it? Or let’s better phrase it: Does automatic mode work with all modules which extend the functionality of PW’s default image field? That would really make optimizing images a no-brainer. :-)

It's not compatible with CI3, but I think I know why and I think I know how to fix it :-) Will report, stay tuned.

Sorry for inconvenience! I just realised that the whole directory was missing on github. I fixed that and also upgraded AS to v1.0.2 that add support for CroppableImage3.

That fixed it. (I was getting the same error.) Works great!

Is there anything I have to set up to use the local optimization tools?

I'm on a shared webspace, but each customer has a separate FastCGI PHP interpreter. So it should work according to the module’s documentation. Or did I miss anything?

The error messages say “Command "jpegoptim" not found.” or the similar message for pngs.

It looks like executable is not found because it's not within the PATH. Do php -r "print getenv('PATH');" from shell or phpinfo(); from php and check for environment variable PATH. Make sure that jpegoptim (and others) are on the path. You could also check what shell is executed: echo shell_exec("echo $0");  It's possible that it's sh and not bash  You may need to use the putenv command or determine whether your path needs to be set in /etc/profile, ~/.profile or ~/.bashrc in order for it to be picked up by the user runing php. Some versions of apache read configuration from /etc/apache2/envvars . You can set environment vars locally within a VirtualHost config using SetEnv. Or it might help if you put putenv('PATH=/your/path'); somewhere in the php, just for the test.

You could also set the path of jpegoptim (and other binaries) by modifying optimizeSettings in AutoSmush.module:

        $this->optimizeSettings = array(
            'ignore_errors'     => false, //in production could be set to true
            'jpegtran_options'  => array('-optimize', '-progressive', '-copy', ' all'),
            'jpegoptim_options' => array('--preserve', '--all-progressive', '--strip-none', '-T' . self::JPG_QUALITY_THRESHOLD),
            'optipng_options'   => array('-i0', '-o2', '-quiet', '-preserve'),
            'advpng_options'    => array('-z', '-3', '-q'),
            'jpegoptim_bin'     => '/path/to/jpegoptim', <== add this line
        );

All this is specific to the environment, so I can't give detail instructions on how to make "Local tools" to work. I'm also not a linux user, I tested tools on windows. Let me know how it goes.

Since my Linux knowledge is quite limited, I had to research and try a bit. Only the last option (inserting the path into the module file) worked – but only for jpegoptim. If i try to upload a png, I receive an error message telling me that the pngquant command doesn’t work, even if the module now knows the path to the binary.

To be honest, that’s too much work to investigate. I just use resmush.it as long as it works.

jpegoptim_bin is just for jpegoptim, the other options are:

  • optipng_bin
  • pngquant_bin
  • pngcrush_bin
  • pngout_bin
  • gifsicle_bin
  • jpegtran_bin

Would it help if you could enter the paths in the module settings page?

Of course I used the individual options.

I also tried commenting out the pngquant_bin setting, hoping that the modiule would go on trying to use the next available PNG optimizer. But it didn’t work. I got the error message that pngquant could not be found.

Hi, sorry for the late reply. I'm using OptimizerFactory library and that's how it works. Quick workaround would be changing the source code in the library, so that only one optimizer would run. Open /site/modules/AutoSmush/image-optimizer/src/ImageOptimizer/OptimizerFactory.php and change to this:

        $this->optimizers['png'] = new ChainOptimizer(array(
            $this->optimizers['optipng'], //reversed the order so optipng is first
            $this->optimizers['pngquant'],
            $this->optimizers['pngcrush'],
            $this->optimizers['advpng']
        //));
        ), true); //if true, just first optimizer will run, if false all optimizers will run

I'll see what I can do, since others that are using this library has similar problems. Author of the library does not response to this issue, but we will find a solution. It might take some time though.

Thanks for the explanation, @matjazp. As I said, I'm fine with being able to use resmush.it via the module, since resmush.it works like a charm, and I don’t have any images which are not sooner or later made publicly available (so there are no privacy issues).

Being independent from resmush.it would be a nice extra, but it’s not really required from my side. This would be interesting for cases where PW and Autosmush are used to build a website for a closed user group with confidential content which should not be send around between servers.

I made some changes in v1.0.4 (just uploaded to GH). At the bottom at the module config you can see what is the path being search for local optimizers (executables) and which optimizers have been found. If optimizer is not found, then it's skipped. I extended the search path so you can put optipng, jpegoptim and gifsicle on the root of PW ($config->paths->root) on templates directory  ($config->paths->templates) and assets directory ($config->paths->assets). If you have shell access then you can install all three mentioned optimizers with apt-get install optipng jpegoptim gifsicle Hope that helps.

Thanks for the great module, but I get the following error in php7 environment. It runs smoothly in php5.

require_once(): Failed opening required '/home/admin/public_html/site/modules/AutoSmush./ImageOptimizer.php' (include_path='.:/usr/share/php')

The error is gone after I change line 5 in AutoSmush.module from

require_once /*NoCompile*/__DIR__ . './ImageOptimizer.php';

to

require_once /*NoCompile*/__DIR__ . '/ImageOptimizer.php';

(remove dot before /ImageOptimizer.php)

 

However, in Local tool optimizers info, the module cannot find any exe.(EDIT: I found that you have posted solution above. Let me try first, thanks)

EDIT: Solved by simply  apt-get install optipng jpegoptim gifsicle

Just before commit to GH I added /*NoCompile*/ option introduced in lasted PW dev and somehow added dot, don't know why  :-) I hope I didn't break other things... It's working fine on windows with php 7.1, tried on linux with php 7.0 and got an error. I just pushed a fix for that. Thx for reporting.

Optimizers on linux: I can't make instructions on how to install them, since there are so many flavors of *x, but it looks like apt-get is now some sort of standard.

I get the following error when installing from PW Modules.

Also tried to download and install direct from github.

It seems to install fine but this error is apparent when I click the Settings button on AutoSmush 1.0.5

I think this was an error from running 2.7.3 (or similar).

Upgraded to 3.0.33 and all is working.

      Page Query Boss
      Build complex nested queries containing multiple fields and pages and return an array or JSON. This is useful to fetch data for SPA and PWA.
      You can use the Module to transform a ProcessWire Page or PageArray – even RepeaterMatrixPageArrays – into an array or JSON. Queries can be nested and contain closures as callback functions. Some field-types are transformed automatically, like Pageimages or MapMarker.
      Installation
      Via ProcessWire Backend
      It is recommended to install the Module via the ProcessWire admin "Modules" > "Site" > "Add New" > "Add Module from Directory" using the PageQueryBoss class name.
      Manually
      Download the files from Github or the ProcessWire repository: https://modules.processwire.com/modules/page-query-builder/
      Copy all of the files for this module into /site/modules/PageQueryBoss/ Go to “Modules > Refresh” in your admin, and then click “install” for the this module. Module Methods
      There are two main methods:
      Return query as JSON
      $page->pageQueryJson($query); Return query as Array
      $page->pageQueryArray($query); Building the query
      The query can contain key and value pairs, or only keys. It can be nested and 
      contain closures for dynamic values. To illustrate a short example:
      // simple query: $query = [ 'height', 'floors', ]; $pages->find('template=skyscraper')->pageQueryJson($query); Queries can be nested, contain page names, template names or contain functions and ProcessWire selectors:
      // simple query: $query = [ 'height', 'floors', 'images', // < some fileds contain default sub-queries to return data 'files' => [ // but you can also overrdide these defaults: 'filename' 'ext', 'url', ], // Assuming there are child pages with the architec template, or a // field name with a page relation to architects 'architect' => [ // sub-query 'name', 'email' ], // queries can contain closure functions that return dynamic content 'querytime' => function($parent){ return "Query for $parent->title was built ".time(); } ]; $pages->find('template=skyscraper')->pageQueryJson($query); Keys:
      A single fieldname; height or floors or architects 
      The Module can handle the following fields:
      Strings, Dates, Integer… any default one-dimensional value Page references Pageimages Pagefiles PageArray MapMarker FieldtypeFunctional A template name; skyscraper or city
      Name of a child page (page.child.name=pagename); my-page-name A ProcessWire selector; template=building, floors>=25
      A new name for the returned index passed by a # delimiter:
      // the field skyscraper will be renamed to "building": $query = ["skyscraper`#building`"]  
      Key value pars:
      Any of the keys above (1-5) with an new nested sub-query array:
      $query = [ 'skyscraper' => [ 'height', 'floors' ], 'architect' => [ 'title', 'email' ], ]  
      A named key and a closure function to process and return a query. The closure gets the parent object as argument:
      $query = [ 'architecs' => function($parent) { $architects = $parent->find('template=architect'); return $architects->arrayQuery(['name', 'email']); // or return $architects->explode('name, email'); } ] Real life example:
      $query = [ 'title', 'subtitle', // naming the key invitation 'template=Invitation, limit=1#invitation' => [ 'title', 'subtitle', 'body', ], // returns global speakers and local ones... 'speakers' => function($page){ $speakers = $page->speaker_relation; $speakers = $speakers->prepend(wire('pages')->find('template=Speaker, global=1, sort=-id')); // build a query of the speakers with return $speakers->arrayQuery([ 'title#name', // rename title field to name 'subtitle#ministry', // rename subtitle field to ministry 'links' => [ 'linklabel#label', // rename linklabel field to minlabelistry 'link' ], ]); }, 'Program' => [ // Child Pages with template=Program 'title', 'summary', 'start' => function($parent){ // calculate the startdate from timetables return $parent->children->first->date; }, 'end' => function($parent){ // calculate the endate from timetables return $parent->children->last->date; }, 'Timetable' => [ 'date', // date 'timetable#entry'=> [ 'time#start', // time 'time_until#end', // time 'subtitle#description', // entry title ], ], ], // ProcessWire selector, selecting children > name result "location" 'template=Location, limit=1#location' => [ 'title#city', // summary title field to city 'body', 'country', 'venue', 'summary#address', // rename summary field to address 'link#tickets', // rename ticket link 'map', // Mapmarker field, automatically transformed 'images', 'infos#categories' => [ // repeater matrix! > rename to categories 'title#name', // rename title field to name 'entries' => [ // nested repeater matrix! 'title', 'body' ] ], ], ]; if ($input->urlSegment1 === 'json') { header('Content-type: application/json'); echo $page->pageQueryJson($query); exit(); } Module default settings
      The modules settings are public. They can be directly modified, for example:
      $modules->get('PageQueryBoss')->debug = true; $modules->get('PageQueryBoss')->defaults = []; // reset all defaults Default queries for fields:
      Some field-types or templates come with default selectors, like Pageimages etc. These are the default queries:
      // Access and modify default queries: $modules->get('PageQueryBoss')->defaults['queries'] … public $defaults = [ 'queries' => [ 'Pageimages' => [ 'basename', 'url', 'httpUrl', 'description', 'ext', 'focus', ], 'Pagefiles' => [ 'basename', 'url', 'httpUrl', 'description', 'ext', 'filesize', 'filesizeStr', 'hash', ], 'MapMarker' => [ 'lat', 'lng', 'zoom', 'address', ], 'User' => [ 'name', 'email', ], ], ]; These defaults will only be used if there is no nested sub-query for the respective type. If you query a field with complex data and do not provide a sub-query, it will be transformed accordingly:
      $page->pageQueryArry(['images']); // returns something like this 'images' => [ 'basename', 'url', 'httpUrl', 'description', 'ext', 'focus'=> [ 'top', 'left', 'zoom', 'default', 'str', ] ]; You can always provide your own sub-query, so the defaults will not be used:
      $page->pageQueryArry([ 'images' => [ 'filename', 'description' ], ]); Overriding default queries:
      You can also override the defaults, for example
      $modules->get('PageQueryBoss')->defaults['queries']['Pageimages'] = [ 'basename', 'url', 'description', ]; Index of nested elements
      The index for nested elements can be adjusted. This is also done with defaults. There are 3 possibilities:
      Nested by name (default) Nested by ID Nested by numerical index Named index (default):
      This is the default setting. If you have a field that contains sub-items, the name will be the key in the results:
      // example $pagesByName = [ 'page-1-name' => [ 'title' => "Page one title", 'name' => 'page-1-name', ], 'page-2-name' => [ 'title' => "Page two title", 'name' => 'page-2-name', ] ] ID based index:
      If an object is listed in $defaults['index-id'] the id will be the key in the results. Currently, no items are listed as defaults for id-based index:
      // Set pages to get ID based index: $modules->get('PageQueryBoss')->defaults['index-id']['Page']; // Example return array: $pagesById = [ 123 => [ 'title' => "Page one title", 'name' => 123, ], 124 => [ 'title' => "Page two title", 'name' => 124, ] ] Number based index
      By default, a couple of fields are transformed automatically to contain numbered indexes:
      // objects or template names that should use numerical indexes for children instead of names $defaults['index-n'] => [ 'Pageimage', 'Pagefile', 'RepeaterMatrixPage', ]; // example $images = [ 0 => [ 'filename' => "image1.jpg", ], 1 => [ 'filename' => "image2.jpg", ] ] Tipp: When you remove the key 'Pageimage' from $defaults['index-n'], the index will again be name-based.
       
      Debug
      The module respects wire('config')->debug. It integrates with TracyDebug. You can override it like so:
      // turns on debug output no mather what: $modules->get('PageQueryBoss')->debug = true; Todos
      Make defaults configurable via Backend. How could that be done in style with the default queries?

      General
      This is a lightweight alternative to other newsletter & newsletter-subscription modules.
      It can subscribe, update, unsubscribe & delete a user in a list in Mailchimp with MailChimp API 3.0. It does not provide any forms or validation, so you can feel free to use your own. To protect your users, it does not save any user data in logs or sends them to an admin.
      This module fits your needs if you...
      ...use Mailchimp as your newsletter / email-automation tool ...want to let users subscribe to your newsletter on your website ...want to use your own form, validation and messages (with or without the wire forms) ...don't want any personal user data saved in any way in your ProcessWire environment (cf. EU data regulation terms) ...like to subscribe, update, unsubscribe or delete users to/from different lists ...like the Mailchimp UI for creating / sending / reviewing email campaigns You can find it here: https://github.com/danielstieber/SubscribeToMailchimp
      Let me know what you think and if I should add it to the Modules Directory.
      Setup
      Log into your Mailchimp account and go to  Profile > Extras > API Keys. If you don't have an API Key, create a new one. Copy your API Key and paste it in the module settings (Processwire > Modules > Site > SubscribeToMailchimp). Back in Mailchimp, go to the list, where you want your new subscribers. Go to Settings > List name and defaults. Copy the List ID an paste it in to the module settings.
      Usage
      To use the module, you need to load it into your template:
      $mc = $modules->get("SubscribeToMailchimp"); Now you can pass an email address to the module and it will try to edit (if the user exists) or create a new subscriber in your list.
      $mc->subscribe('john.doe@example.com'); You can also pass a data array, to add additional info.
      $mc->subscribe('john.doe@example.com', ['FNAME' => 'John', 'LNAME' => 'Doe']); You can even choose an alternative list, if you don't want this subscriber in your default list.
      $mc->subscribe('john.doe@example.com', ['FNAME' => 'John', 'LNAME' => 'Doe'], 'abcdef1356'); // Subscribe to List ID abcdef1356 If you want to unsubscribe a user from a list, you can use the unsubscribe method.
      $mc->unsubscribe('john.doe@example.com'); // Unsubscribe john.doe@example.com from the default list $mc->unsubscribe('john.doe@example.com', 'abcdef1356'); // Unsubscribe john.doe@example.com from the list abcdef1356 If you want to permantly delete a user, you can call the delete method. Carefully, this step cannot be undone
      $mc->delete('john.doe@example.com'); // Permanently deletes john.doe@example.com from the default list $mc->delete('john.doe@example.com', 'abcdef1356'); // Permanently deletes john.doe@example.com from the list abcdef1356  
      Important Notes
      This module does not do any data validation. Use a sever-sided validation like Valitron Make sure that you have set up your fields in your Mailchimp list. You can do it at Settings > List fields and *|MERGE|* tags Example
      Example usage after a form is submitted on your page:
      // ... validation of form data $mc = $modules->get("SubscribeToMailchimp"); $email = $input->post->email; $subscriber = [ 'FNAME' => $input->post->firstname, 'LNAME' => $input->post->lastname, ]; $mc->subscribe($email, $subscriber);  
      Troubleshooting
      In case of trouble check your ProcessWire warning logs.
      I can't see the subscriber in the list
      If you have enabled double opt-in (it is enabled by default) you will not see the subscriber, until he confirmed the subscription in the email sent by Mailchimp
      I get an error in my ProccessWire warning logs
      Check if you have the right List ID and API Key. Check if you pass fields, that exist in your list. Check if you pass a valid email address. Go to Mailchimps Error Glossary for more Information
      How To Install
      Download the zip file at Github or clone directly the repo into your site/modules If you downloaded the zip file, extract it in your sites/modules directory. You might have to change the folders name to 'SubscribeToMailchimp'. Goto the modules admin page, click on refresh and install it

      As threatened in the Pub sub forum in the "What are you currently building?" thread, I've toyed around with Collabora CODE and built file editing capabilities for office documents (Libre-/OpenOffice formats and MS Office as well as a few really old file types) into a PW module.
      If you are running OwnCloud or NextCloud, you'll perhaps be familiar with the Collabora app for this purpose.
      LoolEditor
      Edit office files directly in ProcessWire
      Edit your docx, odt, pptx, xlsx or whatever office files you have stored in your file fields directly from ProcessWire's page editor. Upload, click the edit icon, make your changes and save. Can be enabled per field, even in template context.
      Currently supports opening and saving of office documents. Locking functionality is in development.
      See the README on GitHub for installation instructions. You should be reasonably experienced with configuring HTTPS and running docker images to get things set up quickly.
      Pull requests are welcome!
      Here is a short demonstration:

    • By Robin S
      An Images field allows you to:
      Rename images by clicking the filename in the edit panel or in list view. Replace images, keeping metadata and filename (when possible) by dropping a new image on the thumbnail in the edit panel. Introduced here. But neither of these things is possible in File fields, which prompted this module. The way that files are renamed or replaced in this module is not as slick as in the Images field but it gets the job done. The most time-consuming part was dealing with the UI differences of the core admin themes. @tpr, gives me even more respect for the work that must go into AdminOnSteroids.
      Most of the code to support the rename/replace features is already present in InputfieldFile - there is just no UI for it currently. So hopefully that means these features will be offered in the core soon and this module can become obsolete.
       
      Files Rename Replace
      Allows files to be renamed or replaced in Page Edit.

      Usage
      Install the Files Rename Replace module.
      If you want to limit the module to certain roles only, select the roles in the module config. If no roles are selected then any role may rename/replace files.
      In Page Edit, click "Rename/Replace" for a file...
      Rename
      Use the text input to edit the existing name (excluding file extension).
      Replace
      Use the "Replace with" select to choose a replacement file from the same field. On page save the file will be replaced with the file you selected. Metadata (description, tags) will be retained, and the filename also if the file extensions are the same.
      Tip: newly uploaded files will appear in the "Replace with" select after the page has been saved.

    • By d'Hinnisdaël
      So I decided to wade into module development and created a wrapper module around ImageOptim, a service that compresses and optimizes images in the cloud. ImageOptim currently handles JPG, PNG and GIF files and, depending on the settings you use, shaves off between 15% and 60% in filesize. Great for bandwidth and great for users, especially on mobile.
      This module handles the part of uploading images to ImageOptim via their official API, downloading the optimized version and storing it alongside the original image.
       

       
      Download & Info
      GitHub / Module directory / Readme / Usage
       
      Why ImageOptim?
      There are other image optimization services out there, some of them free, that have outstanding ProcessWire modules. A few things make ImageOptim the best tool for most of my customers: It's not free, i.e. it will probably be around for a while and offers support. However, it's cheaper than some of the bigger competitors like Cloudinary. And it does PNG compression better than any of the free services out there, especially those with alpha channels.
       
      Installation
      Install the module like any other ProcessWire module, by either copying the folder into your modules folder or installing it via the admin. See above for downloads links on GitHub and in the module directory.
       
      Requirements
      To be able to upload images to the service, allow_url_fopen must be set on the server. The module will abort installation if that's not the case.
      I have only tested the module on ProcessWire 3.x installations. I don't see why it shouldn't work in 2.x, if anyone wants to try it out and report back.
       
      ImageOptim account
      To compress images, you first need to sign up for an ImageOptim account. They offer free trials to try the service.
       
      Usage (manual optimization)
      Images can be optimized by calling the optimize() method on any image. You can pass an options array to set ImageOptim API parameters.
      $image->size(800,600)->optimize()->url $image->optimize(['quality' => 'low', 'dpr' => 2]) // Set quality to low and enable hi-dpi mode
      Automatic optimization
      The module also has an automatic mode that optimizes all image variations after resizing. This is the recommended way to use this module since it leaves the original image uncompressed, but optimizes all derivative images.
      $image->size(800,600)->url // nothing to do here; image is optimized automatically
      To change compression setting for single images, you can pass an options array along with the standard ImageResizer options. Passing false disables optimization.
      $image->size(800, 600, ['optimize' => 'medium']) $image->size(800, 600, ['optimize' => ['quality' => 'low', 'dpr' => 2]]) $image->size(800, 600, ['optimize' => false])
      For detailed usage instructions and all API parameters, see the usage instructions on GitHub.
       
      Filenames
      Optimized images will be suffixed, e.g. image.jpg becomes image.optim.jpg. You can configure the suffix in the module settings.
       
      Roadmap
      Asynchronous processing. Not really high on the list. Image variations need to be created anyway, so waiting a few seconds longer on first load is preferable to adding complexity to achieve async optimization. Optimize image variations created by other modules. CroppableImage comes to mind. I don't use any of these, so if somebody wants to help out and submit a pull request — all for it! Add a dedicated page in the setup menu with a dashboard and detailed statistics. ImageOptim's API is very barebones for now, so not sure if that's feasible or even necessary.
      Stability
      I've been using this module on production sites for some time now, without hiccups. If you do notice oddities, feel free to comment here or investigate and submit PRs.
