How do you create a thumbnail image out of a JPEG in Java?

Question

Can someone please help with some code for creating a thumbnail for a JPEG in Java.

I\'m new at this, so a step by step explanation would be appreciated.

Answer 1

I know this is a pretty old post. I have been looking for a solution to generate the thumbnail so end up using this

Thumbnails.of(originalImage).scale(0.25).asBufferedImage();

if you are using for mobile would suggest to set the scale to 0.45

Thumbnails.of(originalImage).scale(0.45).asBufferedImage();

This is certainly much faster using the Graphics2D as have tested the both options.
