Image Animated GIF

Recommended Posts

Image Animated GIF  v 2.0.2
 
Module for PW 2.5 stable or newer, but is obsolete for PW Versions greater then 3.0.89 (... read more ...)
 
This module helps with resizing and cropping of animated GIFs when using the GD-Library.
The GD-Library does not support this.


This module is completely based upon the fantastic work of

   László Zsidi (http://www.gifs.hu/, builts the initial classes)

   xurei (https://github.com/xurei/GIFDecoder_optimized, enhanced the classes)


I have ported it to a PW module and it works with core imagefields, together with Pia and with CropImagefields that uses the new naming scheme since PW 2.5.

You can find it in the modules directory: https://modules.processwire.com/modules/image-animated-gif/

and on Github: https://github.com/horst-n/ImageAnimatedGif

So, if you feel a bit retro one day and want to upload some animated GIFs to a PW site, first download and install this module. ;)

Was just reminded of this module as I stumbled upon the Wild Beasts x Mattis Dovier GIF-novel. Also read an interview where the artist (at least I think it was him..) declared that GIF is making a come-back, or something.

Can't really disagree after seeing the GIF-novel :)

@teppo, I've got to agree that animated gifs may be making a comeback. We wanted an (intentionally cheesy) animated banner for a site of ours and decided not to use Flash due to lack of support on mobile, so we went with a gif. (When our designer finishes it...)

Now to see whether they can be made responsive...

Awesome, horst. I want this in PW core! Dealing with the issue of resizing animated gifs was each time a pain in the ass. Actually I have a project coming up with an image grid that contains several animated gifs. So I will definitely give it a try.

There is no special php code. The module, once it is installed, hooks into PWs core Pageimage / ImageSizer and automatically should detect and handle animated GIFs. It should work with the normal API calls, like $image->width(320).

So, your example variation looks a bit weird. :)

Can you give some more infos about PW Version, PHP Version, other image related installed modules, please?

Hi, I have figured out that the LIBs I have ported to a PW module somehow interprets your background color as a transparent color index, OR as not changed imageparts that could be removed from the next slide(s).

So, as it is definetly wrong, I'm not able to support the original LIBs. Maybe you can try to contact the original author? If not, I will put this on my ToDo.

For now I only can tell you a not very conveniant workaround. I have found out that, if the backgrounds of the slides have some noise, it works as expected. But it increases the final filesize significantly (400%)!

BTW: welcome to PW :)

I am using PW 2.5.3 with PHP Version 5.3.29 and I'm handling it just how you explained it:

$image->width(320)

I just tried the same with your example gif and it works fine. Obviously there is something wrong with my files.

These are images with pretty high resolution. Are there any limitations due to this?

Here are two example gifs in original dimensions.

Have you read my second post, just above your last?

It doesn't depend on your images, it depends on the original LIBs that I have ported to PW. I will try to research a bit about that, but have not much time at the moment.

I have found the original developer, but he isn't able to maintain / support his LIBs atm. I also have found one Lib here that has a new method that can help in this regard. But unfortunately I do not know how to stuff all resized frames together without black areas or other artefacts. However, the positioning thing I already could solve. :)

I have pushed a dev version to github.
 
It does not support any form of cropping! but it does support size(), width(), height() and Pias contain() & cover(). :)

UPDATE: Now the dev branch also supports centered crop!

Only thing missing is cropping with tools like Thumbnails etc (cropExtra) and other API crop calls then centered are currently not tested. :)

Hey. Super cool. Thank you very much. It works perfekt for me. I do not need cropping right now, so I am totally fine with it.

This support here makes PW even better. Great Work!

Nice to hear that it works perfect for you,

but, ähm,

  • a) I haven't built it just for your current case,
  • b) we need to have support for cropping, definetly,
  • c) but I have pushed the intermediate work to that dev branch to support you with your current case!  ;):lol:

There is currently a dev branch available where I started a complete rewrite of the Module.
 
This is needed because the 1.0.0 Version only handles animated GIFs with photos right, but fails with some sort of graphics:
 
animated-gif-crop3-wrong.gif  animated-gif-crop1-wrong.gif  animated-gif-crop2-wrong.gif

 
After a short and successful research (5 minutes in a support forum thread of László Zsidis GIFdecoder class) I found an enhanced class of GIFdecoder.
With it, I was able to position the frames correct, but has many trouble with background colors and transparency (example).

More can be read here at Github, where I asked xurei, the author of the GIFDecoder_optimized class for help. And with an upload of the corresponding GIFEncoder_optimized class, I was able to submit the manipulated frames with respect for transparency, what the old encoder couldn't handle. Sometimes you get lucky! So, a big big thanks to xurei from all future PW users that need support for animated GIFs with GD-lib. :D
 
The results of the current dev branch, version 1.0.2 looks much better now:

animated-gif-crop3.gif  animated-gif-crop1.gif  animated-gif-crop2.gif
 

Only thing currently missing is cropping with tools like Thumbnails etc (cropExtra). This is on the ToDo.

The module is now fully functional again and its version number is set to 2.0.0, because it was a full rewrite.

 
Finally it supports all sorts of crops again:

 
animated-gif-zweinull-cropextra.gif  cropExtra what is needed by CroppingTools



animated-gif-zweinull-north.gif  north

                            -

animated-gif-zweinull-south.gif  south

animated-gif-zweinull-west.gif   animated-gif-zweinull-east.gif

           west           |         east

And by x/y params and centered of course too.

I updated the first post here in the thread, where yo can find the links to Github and the modules directory.

I wasn't sure if this was a default quality setting on the module, that was all!

Aha, but in your first post you was talking about "severe quality loss" of images, without showing an example.

What have you expected as (serious) answer?

(please keep in mind that I know that GIF does not have an option for quality setting. There is no chance for me to think of something in regard to quality-setting.)

------

GIF does not have any quality- setting / option by design of the image format.

PNG also does not have this. PNG has an option for compression, but this does not affect the visual quality.

JPEG is the only image format that has a setting for visual quality.

------

So, when ever talking about visual and also (by its nature) individually different interpreted aspects of images, it is best to  show an example. :)

      A community member raised a question and I thought a new sanitizer method for the purpose would be useful, hence...
      Sanitizer Transliterate
      Adds a transliterate method to $sanitizer that performs character replacements as defined in the module config. The default character replacements are based on the defaults from InputfieldPageName, but with uppercase characters included too.
      Usage
      Install the Sanitizer Transliterate module.
      Customise the character replacements in the module config as needed.
      Use the sanitizer on strings like so:
      $transliterated_string = $sanitizer->transliterate($string);

      Hello,
      this module can publish content of a Processwire page on a Facebook page, triggered by saving the Processwire page.
      To set it up, configure the module with a Facebook app ID, secret and a Page ID. Following is additional configuration on Facebook for developers:
      Minimum Required Facebook App configuration:
      on Settings -> Basics, provide the App Domains, provide the Site URL, on Settings -> Advanced, set the API version to 2.10, add Product: Facebook Login, on Facebook Login -> Settings, set Client OAuth Login: Yes, set Web OAuth Login: Yes, set Enforce HTTPS: Yes, add "http://www.example.com/processwire/page/" to field Valid OAuth Redirect URIs. This module is configurable as follows:
      Templates: posts can take place only for pages with the defined templates. On/Off switch: specify a checkbox field that will not allow the post if checked. Specify a message and/or an image for the post.
      Usage
      edit the desired PW page and save; it will post right after the initial Facebook log in and permission granting. After that, an access token is kept.
       
      Download

      I created a little helper module to trigger a CI pipeline when your website has been changed. It's quite simple and works like this: As soon as you save a page the module sets a Boolean via a pages save after hook. Once a day via LazyCron the module checks if the Boolean is set and sends a POST Request to a configurable Webhook URL.
      Some ideas to extend this:
      make request type configurable (GET, POST) make the module trigger at a specified time (probably only possible with a server cronjob) trigger manually Anything else? If there's interest, I might put in some more functionality. Let me know what you're interested in. Until then, maybe it is useful for a couple of people 🙂

      I created this module a while ago and never got around to publicising it, but it has been outed in the latest PW Weekly so here goes the support thread...
      Unique Image Variations
      Ensures that all ImageSizer options and focus settings affect image variation filenames.

      Background
      When using methods that produce image variations such as Pageimage::size(), ProcessWire includes some of the ImageSizer settings (height, width, cropping location, etc) in the variation filename. This is useful so that if you change these settings in your size() call a new variation is generated and you see this variation on the front-end.
      However, ProcessWire does not include several of the other ImageSizer settings in the variation filename:
      upscaling cropping, when set to false or a blank string interlace sharpening quality hidpi quality focus (whether any saved focus area for an image should affect cropping) focus data (the top/left/zoom data for the focus area) This means that if you change any of these settings, either in $config->imageSizerOptions or in an $options array passed to a method like size(), and you already have variations at the requested size/crop, then ProcessWire will not create new variations and will continue to serve the old variations. In other words you won't see the effect of your changed ImageSizer options on the front-end until you delete the old variations.
      Features
      The Unique Image Variations module ensures that any changes to ImageSizer options and any changes to the focus area made in Page Edit are reflected in the variation filename, so new variations will always be generated and displayed on the front-end.
      Installation
      Install the Unique Image Variations module.
      In the module config, set the ImageSizer options that you want to include in image variation filenames.
      Warnings
      Installing the module (and keeping one or more of the options selected in the module config) will cause all existing image variations to be regenerated the next time they are requested. If you have an existing website with a large number of images you may not want the performance impact of that. The module is perhaps best suited to new sites where image variations have not yet been generated.
      Similarly, if you change the module config settings on an existing site then all image variations will be regenerated the next time they are requested.
      If you think you might want to change an ImageSizer option in the future (I'm thinking here primarily of options such as interlace that are typically set in $config->imageSizerOptions) and would not want that change to cause existing image variations to be regenerated then best to not include that option in the module config after you first install the module.

      I've created a small module which lets you define a timestamp after which a page should be accessible. In addition you can define a timestamp when the release should end and the page should not be accessable any more.
      ProcessWire-Module: http://modules.processwire.com/modules/page-access-releasetime/
      Github: https://github.com/Sebiworld/PageAccessReleasetime
      Usage
      PageAccessReleasetime can be installed like every other module in ProcessWire. Check the following guide for detailed information: How-To Install or Uninstall Modules
      After that, you will find checkboxes for activating the releasetime-fields at the settings-tab of each page. You don't need to add the fields to your templates manually.
      Check e.g. the checkbox "Activate Releasetime from?" and fill in a date in the future. The page will not be accessable for your users until the given date is reached.
      If you have $config->pagefileSecure = true, the module will protect files of unreleased pages as well.
      How it works
      This module hooks into Page::viewable to prevent users to access unreleased pages:
      public function hookPageViewable($event) { $page = $event->object; $viewable = $event->return; if($viewable){ // If the page would be viewable, additionally check Releasetime and User-Permission $viewable = $this->canUserSee($page); } $event->return = $viewable; } To prevent access to the files of unreleased pages, we hook into Page::isPublic and ProcessPageView::sendFile.
      public function hookPageIsPublic($e) { $page = $e->object; if($e->return && $this->isReleaseTimeSet($page)) { $e->return = false; } } The site/assets/files/ directory of pages, which isPublic() returns false, will get a '-' as prefix. This indicates ProcessWire (with activated $config->pagefileSecure) to check the file's permissions via PHP before delivering it to the client.
      The check wether a not-public file should be accessable happens in ProcessPageView::sendFile. We throw an 404 Exception if the current user must not see the file.
      public function hookProcessPageViewSendFile($e) { $page = $e->arguments[0]; if(!$this->canUserSee($page)) { throw new Wire404Exception('File not found'); } } Additionally we hook into ProcessPageEdit::buildForm to add the PageAccessReleasetime fields to each page and move them to the settings tab.
      Limitations
      In the current version, releasetime-protected pages will appear in wire('pages')->find() queries. If you want to display a list of pages, where pages could be releasetime-protected, you should double-check with $page->viewable() wether the page can be accessed. $page->viewable() returns false, if the page is not released yet.
      If you have an idea how unreleased pages can be filtered out of ProcessWire selector queries, feel free to write an issue, comment or make a pull request!
