Features

• Create high-quality thumbnails from existing images.

Thumbnailator

Graphics.drawImage

• Option to embed a watermark (such as a logo) in the thumbnails.
• Transparency of the watermark is adjustable from transparent (0%) to opaque (100%).

• Supports rotation of thumbnail.

• A fluent interface to simplify the process of making thumbnails programmatically.

For example, the code in the previous example for rotating thumbnails was written as follows:

for (int i : new int[] {0, 90, 180, 270, 45}) {
    Thumbnails.of(new File("coobird.png"))
            .size(100, 100)
            .rotate(i)
            .toFile(new File("image-rotated-" + i + ".png"));
}

• Multiple quality modes for thumbnail generation.
• Preserves the aspect ratio of resulting thumbnail, if desired.
