thanks to hannes, with the latest snapshot (helma-20010820.jar) helma provides an easy (well, at least easier) way to process images:

the image constructor is extended with a second parameter acting as imagefilter:

new Image(url, filter)

such a filter is created by directly accessing the jimi filters package:

Packages.com.sun.jimi.core.filters

Here's an example for 90° ccw rotation:

var img = new Image("eleph.antville.organtville/eleph/dili.jpg"); var rotator = new Packages.com.sun.jimi.core.filters.Rotate(90); var processed = new Image(img, rotator); processed.saveAs("/path/to/static/processed.jpg"); res.write("<img src="/static/processed.jpg&gt;");

other filters need a slightly different approach, e.g. flipping. Here a new function getSource() is introduced to provide the right image class for the filter:

var img = new Image("eleph.antville.organtville/eleph/dili.jpg"); var filter = Packages.com.sun.jimi.core.filters; var flipper = new filter.Flip(img.getSource(), 1); var processed = new Image(img, flipper); processed.saveAs("/path/to/static/processed.jpg"); res.write("<img src="/static/processed.jpg&gt;");

if you are more interested in image processing with helma, i can provide a little example application.

i need to do my personal stuff at the moment, but i keep it in mind.

your other bunch of weblogs... ;->

...don't tell this my boss, m'kay?

i think with the next update one will be able to embed thumbnails also in stories. from there to a popup it's only a small step ;-)

about new versions? i have overwritten almost everything and so i notice changes only accidently. just a quick note is sufficient.

actually i didn't plan to do the update yesterday, but it was a nice evening in hns's office, and shortly before leaving we made the update. i think from now on every update will be described here shortly afterwords, is this ok? (did it several times before, just missed it yesterday :)
