I'm working on a photo gallery application running on Java
6 using Tomcat 6,
JQuery for the client side, and images and xml
generated from Picasa. I needed several
sizes of images for thumbnails and animations and I wasn't about to
create multiple image sizes with Fireworks (I'm a lazy developer).
Doing what every lazy developer does, I search
Google for an image resize solution that would
run on the application server and give me the sizes that I needed and
take the manual work out of the equation. I found several PHP examples
and disjointed Java examples, but no complete solutions. So,
unfortunately I had to do some work to put something together.
Down to brass tax, here's the image resizer servlet code: (copy paste, use as you please)
Hopefully I've contributed something useful to another lazy developer and this solution works. I have no idea how scalable this solution is, nor do I care, it's just for a photo album where I needed cleanly resized images. More articles to come later on the album such as customizing and parsing xml from Picasa and a Java-based Ajax photo gallery using JQuery UI, don't hold your breath though, remember I'm lazy.
