Did you like this plugin? Its development requires a lot of time for me. Please consider the possibility of making a donation: even a coffee is enough! Thank you.

Requirements and supported formats

php-thumber requires GD Library (>=2.0) or Imagick PHP extension (>=6.5.7).

It's highly preferable to use Imagick, because It provides better performance and a greater number of supported formats.

Supported formats may vary depending on the library used.

	JPEG	PNG	GIF	TIF	BMP	ICO	PSD
GD	Yes	Yes	Yes	No	No	No	No
Imagick	Yes	Yes	Yes	Yes	Yes	Yes	Yes

For more information about supported format, please refer to the Intervention Image documentation.

Installation and configuration

You can install the plugin via composer:

$ composer require --prefer-dist mirko-pagliai/php-thumber

Therefore, before using the library, it may be necessary to configure some constants:

• THUMBER_DRIVER: the driver you want to use for the creation of thumbnails. Valid values are imagick or gd;
• THUMBER_TARGET: full path directory where to create thumbnails (so you have to create this directory and make it writable).

An example:

define('THUMBER_DRIVER', 'imagick');
define('THUMBER_TARGET', '/tmp/php-thumber');

Otherwise, you can include/require the config/bootstrap.php file, which will auto-determine the driver to use and set a temporary directory where to create thumbnails (on Unix environment, it will be /tmp/php-thumber).

Installation on older PHP versions

Recent packages and the master branch require at least PHP 7.4 and the current development of the code is based on these and later versions of PHP. However, there are still some branches compatible with previous versions of PHP.

For PHP 7.4 or later

The php7.4 branch requires at least PHP 7.4.

In this case, you can install the package as well:

$ composer require --prefer-dist mirko-pagliai/php-thumber:dev-php7.4

Note that the php7.4 branch will no longer be updated as of January 05, 2024, except for security patches, and it matches the 1.5.5 version.

For PHP 7.2 or later

The php7.2 branch requires at least PHP 7.2.

In this case, you can install the package as well:

$ composer require --prefer-dist mirko-pagliai/php-thumber:dev-php7.2

Note that the php7.2 branch will no longer be updated as of April 28, 2022, except for security patches, and it matches the 1.4.3 version.

For PHP 5.6 or later

The php5.6 branch requires at least PHP 5.6.

In this case, you can install the package as well:

$ composer require --prefer-dist mirko-pagliai/php-thumber:dev-php5.6

Note that the php5.6 branch will no longer be updated as of April 22, 2021, except for security patches, and it matches the 1.2.3 version.

How to use

See our wiki:

• How to use ThumbCreator and create thumbnails.

Refer to our API.

Testing

Some tests belong to the imageEquals group. These tests generate thubnails and compare them with pre-loaded thumbnails (inside tests/examples/comparing_files). By default, these tests are not performed, because the images may be different if generated from different environments and systems.

To exclude these tests, you should run:

vendor/bin/phpunit --exclude-group imageEquals

Versioning

For transparency and insight into our release cycle and to maintain backward compatibility, php-thumber will be maintained under the Semantic Versioning guidelines.
