Download the PHP package plan2net/webp without Composer

On this page you can find all versions of the php package plan2net/webp. It is possible to download/install these versions without Composer. Possible dependencies are resolved automatically.

FAQ

After the download, you have to make one include require_once('vendor/autoload.php');. After that you have to import the classes with use statements.

Example:
If you use only one package a project is not needed. But if you use more then one package, without a project it is not possible to import the classes with use statements.

In general, it is recommended to use always a project to download your libraries. In an application normally there is more than one library needed.
Some PHP packages are not free to download and because of that hosted in private repositories. In this case some credentials are needed to access such packages. Please use the auth.json textarea to insert credentials, if a package is coming from a private repository. You can look here for more information.

  • Some hosting areas are not accessible by a terminal or SSH. Then it is not possible to use Composer.
  • To use Composer is sometimes complicated. Especially for beginners.
  • Composer needs much resources. Sometimes they are not available on a simple webspace.
  • If you are using private repositories you don't need to share your credentials. You can set up everything on our site and then you provide a simple download link to your team member.
  • Simplify your Composer build process. Use our own command line tool to download the vendor folder as binary. This makes your build process faster and you don't need to expose your credentials for private repositories.

Informations about the package webp

WebP for TYPO3 CMS

What does it do?

Adds an automagically created WebP copy for every processed jpg/jpeg/png/gif image in the format

original.ext.webp

What is WebP and why do I want it?

WebP is a modern image format that provides superior lossless and lossy compression for images on the web. Using WebP, webmasters and web developers can create smaller, richer images that make the web faster.

WebP lossless images are 26% smaller in size compared to PNGs. WebP lossy images are 25-34% smaller than comparable JPEG images at equivalent SSIM quality index.

Lossless WebP supports transparency (also known as alpha channel) at a cost of just 22% additional bytes. For cases when lossy RGB compression is acceptable, lossy WebP also supports transparency, typically providing 3× smaller file sizes compared to PNG.

Installation

Add via composer:

composer require "plan2net/webp"

Update

Requirements

You can either use the installed Imagemagick or GraphicsMagick you already use for TYPO3 image manipulation if it supports webp (see below) or you can use any other external binary available on your server (e.g. cwebp).

You can test the support of GraphicsMagick with e.g.:

gm version | grep WebP

(should return yes)

or using ImageMagick with e.g.:

convert version | grep webp

(should return a list of supported formats including webp)

These are examples, check your system documentation for further information on how to verify webp support on your platform.

Extension settings

You can set parameters for the conversion in the extension configuration.

parameters

You find a list of possible options here:

https://www.imagemagick.org/script/webp.php http://www.graphicsmagick.org/GraphicsMagick.html

If you want to use an external binary, you have to supply an option string with exactly two %s placeholders for the original file and the target file name. E.g.:

https://developers.google.com/speed/webp/docs/cwebp

Warning

Try to set a higher value for quality first if the image does not fit your expectations, before trying to use webp:lossless=true, as this could even lead to a higher filesize than the original!

convert_all

# cat=basic; type=boolean; label=Convert all images in local and writable storage and save a copy in Webp format; disable to convert images in the _processed_ folder only
convert_all = 1

Since version 1.1.0 all images in every local and writable storage will be saved as a copy in Webp format by default (instead of just images modified by TYPO3 in the storage's processed folder). If you want to revert to the previous behaviour, set this flag to false (disable the checkbox).

silent

# cat=basic; type=boolean; label=Suppress output (stdout, stderr) from the external converter command
silent = 1

Since version 2.2.0 you can suppress output (stdout, stderr) from the external converter (Linux only).

hide_webp

# cat=basic; type=boolean; label=Hide .webp files in backend file list module
hide_webp = 1

.webp files are hidden by default in the backend file list module. If you want to show them to the users, disable this option.

If you need a more customized behaviour for hiding or showing the generated files (e.g. for a specific BE user group), you can always remove or change the $GLOBALS['TYPO3_CONF_VARS']['SYS']['fal']['defaultFilterCallbacks'] settings (see ext_localconf.php for details) in your own extension.

exclude_directories

# cat=basic; type=string; label=Exclude processing of images from specific directories (separated by semicolon)
exclude_directories =

Here you can exclude processing of images from specific directories. Example value: /fileadmin/demo/special;/another-storage/demo/exclusive

use_system_settings

# cat=basic; type=boolean; label=Use the system GFX "processor_stripColorProfileCommand"/"processor_stripColorProfileParameters" setting for the MagickConverter converter
use_system_settings = 1

When set (default) the value from $GLOBALS['TYPO3_CONF_VARS']['GFX']['processor_stripColorProfileCommand'] or $GLOBALS['TYPO3_CONF_VARS']['GFX']['processor_stripColorProfileParameters'] is appended automatically to the configuration options for the MagickConverter converter, so you don't need to repeat the settings.

Webserver example configuration

Please adapt the following to your specific needs, this is only an example configuration.

nginx

Add a map directive in your global nginx configuration:

map $http_accept $webp_suffix {
    default   "";
    "~*webp"  ".webp";
}

If you use Cloudflare the following might better suit your needs:

map $http_accept $webpok {
    default   0;
    "~*webp"  1;
}

map $http_cf_cache_status $iscf {
    default   1;
    ""        0;
}

map $webpok$iscf $webp_suffix {
    11          "";
    10          ".webp";
    01          "";
    00          "";
}

Add these rules to your server configuration:

location ~* ^.+\.(png|gif|jpe?g)$ {
        add_header Vary "Accept";
        add_header Cache-Control "public, no-transform";
        try_files $uri$webp_suffix $uri =404;
}

Make sure that there are no other rules that prevent further rules or already apply to the specified image formats and prevent further execution!

You can also add a browser restriction if your audience uses old versions of Safari, etc., so no webp is served to them.

location ~* ^.+\.(png|gif|jpe?g)$ {
    if ($http_user_agent !~* (Chrome|Firefox|Edge)) {
        set $webp_suffix "";
    }
    …

Apache (.htaccess example)

We assume that module mod_rewrite.c is enabled.

RewriteEngine On
AddType image/webp .webp

is already part of the TYPO3 htaccess template in typo3/sysext/install/Resources/Private/FolderStructureTemplateFiles/root-htaccess

RewriteCond %{HTTP_ACCEPT} image/webp
RewriteCond %{REQUEST_FILENAME} (.*)\.(?i:png|gif|jpe?g)$
RewriteCond %{REQUEST_FILENAME}\.webp -f
RewriteRule ^ %{REQUEST_FILENAME}\.webp [L,T=image/webp]

<IfModule mod_headers.c>
    <FilesMatch "\.(png|gif|jpe?g)$">
        Header append Vary Accept
    </FilesMatch>
</IfModule>

Make sure that there are no other rules that prevent further rules or already apply to the specified image formats and prevent further execution!

You can also add a browser restriction if your audience uses old versions of Safari, etc., so no webp is served to them.

RewriteCond %{HTTP_ACCEPT} image/webp
RewriteCond %{HTTP_USER_AGENT} ^.*(Chrome|Firefox|Edge).*$ [NC]
…

Verify successful webp image generation and delivery

To make sure that everything works as expected you need to check two things:

  1. WebP image generation on the webserver
  2. successful delivery of WebP images to the client

WebP image generation

Go to fileadmin/_processed_ and check the subfolders for files with .webp extension. For every processed image file there should be a second file with the same filename plus .webp extension:

Delivery of WebP images to the client

Open a processed jpg or png image (see above) in your browser, e.g. https://domain.tld/fileadmin/_processed_/b/2/csm_foo-bar_4f3d6bb7d0.jpg

Check the response headers in the developer tools of your browser. Despite the file suffix .jpg, you should get Content-Type: image/webp.

Troubleshooting and logging

If something does not work as expected take a look at the log file. Every problem is logged to the TYPO3 log (since version 2.0), normally found in var/log/typo3_*.log

Converted files that are larger than the original are removed automatically (since version 2.1.0) and the conversion will not be retried with the same configuration.

If you find that your webp images don't look like the original images (much darker, for example), make sure you have the correct profile set in the system setting GFX/processor_colorspace (e.g. sRGB). Remember to clean up any processed files after this change.

Removing processed files

You can remove the created .webp files at any time within the TYPO3 CMS backend.

Although the button names only the path of the _processed_ folder, all processed files of the storage are actually deleted!

Alternatives

You can get an equal result with using the Apache _modpagespeed or nginx _ngxpagespeed modules from Google https://developers.google.com/speed/pagespeed/module/ with a configuration like:

pagespeed EnableFilters convert_jpeg_to_webp;
pagespeed EnableFilters convert_to_webp_lossless;

but that requires more knowledge to set up.

Drawbacks to keep in mind

Note that this extension produces an additional load on your server (each processed image is reprocessed) and possibly creates a lot of additional files that consume disk space (size varies depending on your! configuration).

Inspiration

This extension was inspired by Angela Dudtkowski's _cswebp extension that has some flaws and got no update since early 2017. Thanks Angela :-)

Thanks to Xavier Perseguers for the Cloudflare hint.

Thanks to Marcus Förster for simplifying the Apache rewrite rules.
