The Thumbnail Generator will help you overcome the limitations on thumbnails creation imposed by Liferay. It allows you to create an unlimited number of thumbnails in a totally customized way.

Requirements :
You need to install the ImageMagick library. Go to http://www.imagemagick.org/script/download.php ,"> http://www.imagemagick.org/script/download.php , select an executable depending on your operating system and follow the wizard.
On Unix, you can also install it by package manager, ex: apt-get install imagemagick.

Configuration :
Before using the Thumbnail Generator, you have to configure it. Go to Menu -> Control Panel -> Configuration -> System Settings -> Thumbnail Configuration. Add at least one file type (ex: jpg) and one command line (ex: img_480:convert -resize 480×270 ) and save the configuration.

Note : on Windows, the 'convert' command may execute a program other than ImageMagick. To call the right command, replace 'convert' by 'magick', (ex: img_480:magick -resize 480×270 )

You are now ready to use the Thumbnail Generator !

Add an image in your application and try to get the thumbnail that was automatically generated by adding the parameter 'thumb=img_480' in the URL of the image. (ex: http://localhost:8080/documents/20147/0/test.jpg/0d72d709-3e48-24b3-3fe6-e39a3c528725?version=1.0&t=1494431839298&imagePreview=1&thumb=img_480) Le Thumbnail Generator vous aidera à dépasser les limitations en matière de création de thumbnails imposées par Liferay.
