[Resin-interest] help on resizing image

[Riccardo Cohen]

Hello
On my web application, I need to resize images sent via multipart forms.

When I try a console application using awt on my mac (see attached 
code), the console application starts a real Mac application with window 
and menu, while my code is only calling non-gui functions 
(ImageIO.read...) .


I'm really affraid to add this code on my server, and I wonder if this 
may have impact on memory, performance and stability of the server. I 
would rather prefer a little imaging library like jmagick or gd for 
java, small and efficient. It's not 100% java but it does not create 
windows and menus...


What do you use to resize images on the server size ?
Thanks a lot.

We use JAI in one of our web apps. Have you set system properties 
java.awt.headless=true and java.awt.headlesslib=true ...?

(Btw, for full performance, you should install JNI binaries. Thought 
that wouldn't be 100% Java either. And I haven't tried it.)

I didn't know about properties "java.awt.headless=true". I'll try 
jmagick wich seems to be a good choice for performance.

Thanks a lot

Using JMagick on resin 3.0.23 (IIRC) we were able to handle a portal where
customers used to upload their photos which got resized to required
600x600.

Did not notice any CPU usage or memory usage issues.
