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Module for PW 2.5 stable or newer, but is obsolete for PW Versions greater then 3.0.89 (...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.

Jep. I got it. Thanks for helping me at this point. :)

I'll try to contact the original author but I appreciate it a lot if you'll try to do further research. 

Thanks.

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. :)

      MediaLibrary
      Update: MediaLibrary can now be found in the official module list.
      Out of necessity, I've started to implement a simple media library module.
      The basic mechanism is that it adds a MediaLibrary template with file and image fields. Pages of this type can be added anywhere in the page tree.
      The link and image pickers in CKEditor are extended to allow quick selection of library pages from dropdowns. In the link picker this happens in the MediaLibrary tab, where you can also see a preview of the selected image. In the image picker, simply select a library from the dropdown at the top, everything else is handled by standard functionality.
      I've put the code onto github. This module is compatible with ProcessWire 3.
      Steps to usage:
      Download the module's zip from github (switch to the pw3 branche beforehand if you want to test on PW 3.x) and unpack it into site/modules Click "Modules" -> "Refresh" in the admin Click "Install" for MediaLibrary For testing, create a page with the MediaLibrary template under home (give it an expressive title like 'Global Media') and add some images and files Edit a differnt page with a CKEditor field and add a link and an image to see the MediaLibrary features in action (see the screencap for details) Optionally, go into the module settings for MediaLibrary Note: this module is far from being as elaborate as Kongondo's Media Manager (and doesn't plan to be). If you need a feature-rich solution for integrated media management, give it a look.
      Feel free to change the settings for MediaFiles and MediaImages fields, just keep the type as multiple.
      There are some not-so-pretty hacks for creating and inserting the correct markup, which could probably be changed to use standard input fields, though I'm a bit at a loss right now how to get it to work. I've also still got to take a look at error handling before I can call it fit for production. All feedback and pointers are appreciated (that's also why I post this in the development section).

      Edit 09.03.2016 / version 0.0.4: there's now also a "Media" admin page with a shortcut to quickly add a new library.

      Edit 01.05.2016:
      Version 0.0.8:
      - The module now supports nested media libraries (all descendants of eligible media libraries are also selectable in link/image picker).
      - There's a MediaLibrary::getPageMediaLibraries method you can hook after to modify the array of available libraries.
      - You can switch between (default) select dropdowns or radio boxes in the module configuration of MediaLIbrary to choose libraries.
      Edit 10.10.2018:
      Version 0.1.3:
      - Dropped compatibility for ProcessWire legacy versions by adding namespaces
      - Allow deletion of libraries from the Media overview admin page
      - Added an option to hide media libraries from the page tree (optionally also for superusers)

      This module corrects a few things that I find awkward about the "Add New Template" workflow in the PW admin. I opened a wishlist topic a while back because it would good to resolve some of these things in the core, but this module is a stopgap for now.
      Originally I was going to share these as a few standalone hooks, but decided to bundle them together in a configurable module instead.
      Add Template Enhancements
      A module for ProcessWire CMS/CMF. Adds some efficiency enhancements when adding or cloning templates via admin.

      Features
      Derive label from name when new template added: if you like to give each of your templates a label then this feature can save some time. The label can be added automatically when templates are added in admin, in admin/API, or not at all. There are options for underscore/hyphen replacement and capitalisation of the label. Edit template after add: when adding only a single template, the template is automatically opened for editing after it is added. Copy field contexts when cloning: this copies the field contexts (a.k.a. overrides such as column width, label and description) from the source template to the new template when using the "Duplicate/clone this template?" feature on the Advanced tab. Copy field contexts when duplicating fields: this copies the field contexts if you select the "Duplicate fields used by another template" option when adding a new template. Usage
      Install the Add Template Enhancements module.
      Configure the module settings according to what suits you.

      As I mentioned in this issue, I've create a new textformatter for ParsedownExtraPlugin, which adds some oomph to your markdown.
      Repo: Parsedown Extra Plugin
      Unlike the built-in textformatter for Parsedown and Parsedown Extra, this should be used when you want to use Extra with additional configuration/customisation.
      Some examples:
      ### Test {.heading} - A [external link](https://google.com/){.google} with `google` as a class that opens in a new tab if the config property is set. - [Another link](/page){target=_blank} that opens in a new tab even though it isn't external. ```html .html <p>Test</p> ``` There's some config options available to you, such as setting attributes on all/external images and links, setting table and table-cell alignment classes, adjusting footnote classes and IDs, adding <code> attributes to their parent <pre> elements, and changing the <code> class if your syntax highlighter does not use language-*.
      I was thinking about adding the ability to make links open in a new tab by appending a plus to the link syntax, but only external links should be opening in a new tab anyway. Further, this would add extra, unnecessary processing time.
      Please let me know if you bump into any problems. ☺️

      TextformatterTypographer (0.4.0 Beta)
      A ProcessWire wrapper for the awesome PHP Typography class, originally authored by KINGdesk LLC and enhanced by Peter Putzer in wp-Typography. Like Smartypants, it supercharges text fields with enhanced typography and typesetting, such as smart quotations, hyphenation in 59 languages, ellipses, copyright-, trade-, and service-marks, math symbols, and more.
      Learn more on my blog
      It's based on the PHP-Typography library found over at wp-Typography, which is more frequently updated and feature rich that its original by KINGdesk LLC.
      The module itself is fully configurable. I haven't done extensive testing, but there is nothing complex about this, and so I only envisage a typographical bug here and there, if any.
      Please do test it out and let me know what you think.
      Also note that I have indicated support for PW 2.8, but I haven't tested there as yet. This was built on PW 3.0.42/62.

      Jumplinks for ProcessWire
      Release: 1.5.50
      Jumplinks is an enhanced version of the original ProcessRedirects by Antti Peisa.
      The Process module manages your permanent and temporary redirects (we'll call these "jumplinks" from now on, unless in reference to redirects from another module), useful for when you're migrating over to ProcessWire from another system/platform. Each jumplink supports wildcards, shortening the time needed to create them.
      Unlike similar modules for other platforms, wildcards in Jumplinks are much easier to work with, as Regular Expressions are not fully exposed. Instead, parameters wrapped in curly braces are used - these are described in the documentation.
      Under Development: 2.0, to be powered by FastRoute
      As of version 1.5.0, Jumplinks requires at least ProcessWire 2.6.1 to run.
      View on GitLab
      Download via the Modules Directory
      Read the docs
      Features
      The most prominent features include:
      Basic jumplinks (from one fixed route to another) Parameter-based wildcards with "Smart" equivalents Mapping Collections (for converting ID-based routes to their named-equivalents without the need to create multiple jumplinks) Destination Selectors (for finding and redirecting to pages containing legacy location information) Timed Activation (activate and/or deactivate jumplinks at specific times) 404-Monitor (for creating jumplinks based on 404 hits) Additionally, the following features may come in handy:
      Stale jumplink management Legacy domain support for slow migrations An importer (from CSV or ProcessRedirects) Feedback & Feature Requests
      I’d love to know what you think of this module. Please provide some feedback on the module as a whole, or even regarding smaller things that make it whole. Also, please feel free to submit feature requests and their use-cases.
      Note: Features requested so far have been added to the to-do list, and will be added to 2.0, and not the current dev/master branches.
      Open Source

      Jumplinks is an open-source project, and is free to use. In fact, Jumplinks will always be open-source, and will always remain free to use. Forever. If you would like to support the development of Jumplinks, please consider making a small donation via PayPal.
      Enjoy!
