Hi Bertrand,
After having a bit of time to think about this I think your suggestion
to have a java component to do this would be a good idea, and if then
there is a specific image scripting language built around that then so
be it.
Have spent a bit of time over the past few days looking into and trying
to integrate JAI and ImageIO into a bundle built by maven etc. etc. (and
half the time spent beating my head against a wall). I am not sure how
well using these libraries will work due to having to download them from
Sun's site rather than automatically getting them from a maven repository.
So this has set me back a bit.

Creating a java component (in a bundle) that implements these
operations would make that usable from any scripting language and
servlet, for example:
// myResourceType.png script
var s = sling.getService(org.apache.sling.imaging.Processor);
var p = s.getImageProcessor();
if(request.selectors[0] == "small") {
p.scale = 0.5;
} else {
p.scale = 1;
}
p.rotation = 90;
p.outputFormat = png;
p.watermark = currentNode.getPath() + ".watermark.png";
p.metadata.title = currentNode.title;
p.render(currentNode,response);
And the image processor might also provide a simple way to store the
output in the repository, as an option to dynamic rendering.

Thanks for your suggestions, and I'm sure we'll do our best to help if
you're willing to work on this.
I'm sure you notice my "subtle" hints to people who might contribute
useful stuff to Sling ;-)
Considering that the core is fairly stable now, and that important
functions like what you describe are still missing, I think it's a
really good time to get involved.

Very interested in working on this (doing this outside normal work hours
as a side project, though using sling within work for more general site
development).
Cheers
Bryce
