Working with ORDIMAGE - upload image

Question

I'm working with Oracle interMedia. I use the type ORDIMAGE for saving my pictures in the database.
With JDeveloper I've created a form for uploading the pictures. No problem with that. But is it possible to automatically generate a thumbnail version of the picture and save this one in a second field of the type ORDIMAGE ?
I was thinking of a trigger maybe that, when inserting or updating an image, automatically generates a thumbnail. Has someone experience with this ?
Greetz!

I've got an idea !!!
I remember browsing through the Intermedia documentation that there are methods on the intermedia objects to do exactly that you are trying to do.
I found a code snippet I guess I tried to use, I think it worked.
DECLARE
Image_1 ORDSYS.ORDImage;
BEGIN
SELECT photo INTO Image_1
FROM Photos WHERE photo_id = 1
FOR UPDATE;
-- Convert and replace the image to a thumbnail image
Image_1.process('maxScale=32 32');
UPDATE Photos SET photo = Image_1 WHERE photo_id = 1;
COMMIT;
END;
Maybe this can be a starting point for you, the code actually converts and replaces an image with an thumbnail, it needs to be edited to make it works as a trigger. Try searching the oracle documentation for the "OrdImage.process" procedure it can do a lot with images.
