Re: [Resin-interest] help on resizing image
Hello After some test with jmagick, I found the solution difficult to rely on : - difficult to compile (but succeed at the end) - unstable (some jvm crash) - outputting some unwanted report on stdout (could not stop the verbose option) - strange API (which is not the main point) I finally go back to 100% pure java with awt, but with headless=true which sould solve my problem.

[Resin-interest] help on resizing image
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.) /Mattias - Original Message - Subject: [Resin-interest] help on resizing image Date: Thu, 07 Feb 2013 11:14:00 +0100 From: Riccardo Cohen r.co...@realty-property.com Hello On my web application, I need to resize images sent via multipart forms.

Re: [Resin-interest] help on resizing image
I didn't know about properties java.awt.headless=true. I'll try jmagick wich seems to be a good choice for performance.
