The cropping is not working for me. I made a new issue for it. I tried and got the same response on both the dev and production 1.4.2. http://code.google.com/p/googleappengine/issues/detail?id=4763 -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.

Re: [appengine-java] Re: Blobstore API vs Datastore API
This won't work either. I get the same funky colors. So far I think the cropping does not work at all. leftX = .05D; topY = .05D; rightX = .10D; bottomY = .10D; oldImage = ImagesServiceFactory.makeImageFromBlob(new BlobKey(fd.getBlobData().getKey())); Transform transform = ImagesServiceFactory.makeCrop(leftX, topY, rightX, bottomY); Image newImage = imagesService.applyTransform(transform, oldImage); -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.

Re: [appengine-java] Re: Blobstore API vs Datastore API
Its pretty easy to store the blobkey in the datastore with the parameters needed to find the blob in the blobstore, all you then need is that blobkey, and serve it from the blobstore, and the only latency you get is for the session loading if one is not loaded.

Re: [appengine-java] Re: Blobstore API vs Datastore API
I decided to go with datastore since I'll be storing simple thumbnail images - nothing more than 100kb. I'm a bit afraid of the 30s limit but I suppose it makes sense for Google. I work for a bioinformatics group known at global level and I'm trying to show my team the power of App Engine; hopefully I can give them enough good examples to make a radical business change happen towards App Engine. It's funny because some colleagues have doubted the uptime of Google and disaster recovery scene, saying that we should have in-house hosting for reliability - but I find it ridiculous because there's a lot more chance of our in-house network going down rather than Google going down.

The credit option has a budget and you can set it real low. Its unlikely unless you have huge amount of resource use that you'll go over. I've only had cents billed on my upload demo due to the amount of data stored.

[appengine-java] Re: Blobstore API vs Datastore API
Hi Luca, 1 thing before going in the new code: by using the blobs in datastore, the interactive time limit (30s) apply (it does not for the blobstore) I.e., the upload must be finished in 30s after that request is cancelled by gae. It may be harder to achieve even if your image is < 1Mb if the bandwidth is low: mobile, etc.. regards didier On Mar 11, 11:21 pm, Jeff Knox wrote: > The datastore works well for storing images (assuming they are < 1MB).

[appengine-java] Re: Blobstore API vs Datastore API
The datastore works well for storing images (assuming they are < 1MB). So far I haven't had more than about 15 images in the database but I don't think that really matters in terms of speed. My images are 1000 pixels in their longest dimension. I am also using the image API to do some manipulations.

Re: [appengine-java] Re: Blobstore API vs Datastore API
Yes, but not if you want to allow uploads. If you enter your credit card, we will not charge it unless you go over the free quota, even for blobstore. Based on your questions, however, I would suggest further reading of the documentation to understand the limitations and capabilities of App Engine, as we do describe the billing required features. There's no way for us to know in the SDK whether you are billing enabled or not, so it wouldn't make sense to put a nag screen for most users that will just enable billing. http://code.google.com/appengine/docs/quotas.html#Blobstore Based on your feedback, however, we should probably mention that blobstore is billing enabled on this page: http://code.google.com/appengine/docs/python/blobstore/overview.html Ikai Lan Developer Programs Engineer, Google App Engine Blog: http://googleappengine.blogspot.com Twitter: http://twitter.com/app_engine Reddit: http://www.reddit.com/r/appengine On Fri, Mar 11, 2011 at 9:35 AM, Luca Matteis wrote: > Is it possible to store the image directly on disk, as a resource? > > On 3/11/11, Simon Knott wrote: > > The datastore can handle blobs with a maximum size of 1MB, whereas the > > blobstore can handle blobs of 2GB. > > > > -- > > You received this message because you are subscribed to the Google Groups > > "Google App Engine for Java" group. > > To post to this group, send email to > google-appengine-java@googlegroups.com. > > To unsubscribe from this group, send email to > > google-appengine-java+unsubscr...@googlegroups.com. > > For more options, visit this group at > > http://groups.google.com/group/google-appengine-java?hl=en. > > > > > > -- > You received this message because you are subscribed to the Google Groups > "Google App Engine for Java" group. > To post to this group, send email to > google-appengine-java@googlegroups.com. > To unsubscribe from this group, send email to > google-appengine-java+unsubscr...@googlegroups.com. > For more options, visit this group at > http://groups.google.com/group/google-appengine-java?hl=en. > > -- You received this message because you are subscribed to the Google Groups "Google App Engine for Java" group.

Is it possible to store the image directly on disk, as a resource?
