We have an ofbiz service that handles this scenario. Once a day it
sweeps an incoming directory for image files (these are the largest,
aka detail, images), and creates the appropriate thumbnails. It also
does a few other things, like removing the product from certain
internal categories, and adding it to other internal categories. Our
naming scheme and the functionality is rather specific to our setup,
but the resize code itself is trivial. We used Jimi
(
http://java.sun.com/products/jimi/), and a resize to 350x350 would
look something like this:
Image image = Jimi.getImage(incomingFilename);
Image resizedImage = image.getScaledInstance(350, 350,
Image.SCALE_SMOOTH);
Jimi.putImage(resizedImage, outgoingFilename);
something interesting we discovered... simply processing the detail
image file (reading, then writing it out with no resize) reduces the
file size significantly. Also, the resized image quality is quite good.
