Well, JAI seems to be the solution, but as I said: I have yet to find
an example based on JAI which produces high quality results with a
wide range of image sizes without any funky side effects...

Thanks for the article URL. Maybe there is hope and a way to get
image manipulation without having to use ImageMagick. I know the
pains you know, Will, and I would be glad to get them solved. :)

Subject: Re: [magnolia-user] OT: Image scaling algorithm
Thanks Peter and Tobias for the quick replies.
We've used ImageMagick before with good results - it's just really
hard for me to believe, that I need to talk to a C program over JNI
only to get a decent scaled image. And since this makes the
installation of webapps on servers a pain it's no real option for us.
We've also used "getScaledInstance()" in Java. But apparently one
should not go that way.

The more you google the more opinions you get on that topic ;-)

Hi Will
The following article explains the different pitfalls for image
scaling with java quite well. And it includes some code how to do it
right. I don't know if it is the best solution, but it is enough for
me.

If you use the multistep scaling flag of the provided helper method,
ensure that your server has enough memory.

Dear Magnolians
This is quite off-topic, but I'm sure many of you have been faced
by the
same problem: Image scaling in Java.
I tried many different methods, googled for hours if not days, but
either
I'm getting low quality results or the thumbs have other "side
effects" like
a black border on one or two sides...
Does anyone have the definite solution to a problem which really
should not
be rocket science? I hate it when things are oh so easy in
Typo3 :-/
Thanks!
