Re: [appengine-java] Transforming Images from the Blobstore

After you've manipulated the image you need to write the new image back to the Blobstore using an HTTP multi-part/formdata POST. You can do this with the URLFetchService. I do this on my site and have just put a new blog entry up about it here:

[appengine-java] Transforming Images from the Blobstore

I got this example from the site: http://code.google.com/intl/en/appengine/docs/java/images/overview.html I'm using the API in this way: BlobKey blobKey = blobs.get(image); ImagesService imagesService = ImagesServiceFactory.getImagesService();
