What is Thumbnailator?
Thumbnailator is a thumbnail generation library for Java.
Why Thumbnailator?
Making thumbnails in Java can be a fairly difficult task.
Learning how to use the Image I/O API, Java 2D API, image processing, image scaling techniques, ... but fear not! Thumbnailator will take care of all those things for you!
How simple is Thumbnailator?
Thumbnailator's fluent interface can be used to perform fairly complicated thumbnail processing task in one simple step.
For example, creating ">JPEG thumbnails of image files in a directory, all resized to a maximum dimension of 640 pixels by 480 pixels while preserving the aspect ratio of the original image can be performed by the following:
Thumbnails.of(new File("path/to/directory").listFiles())
.size(640, 480)
.outputFormat("jpg")
.toFiles(Rename.PREFIX_DOT_THUMBNAIL);
The fluent interface provided by the Thumbnailator simplifies the task of making thumbnails into a single method call!
No need to access the Image I/O API and manually manipulating BufferedImages through Graphics2D objects. Thumbnailator does all of that for you.
