Works fine for certain image sizes, but not all are displayed correctly. Why's that?

Thanks

Hi Alexey, I've implemented the image url deepzoom taking your suggestion, thanks. One more question: should the tile image size be determined from the image actual size? Or is this independent? Thanks again.

I think yes.. you should rewrite some code using WebClient which will download external image.

Is it possible to use this example to deep zoom images not stored locally, but speciyfing their url ? (for example: http://www.ole.clarin.com/diario/2009/08/23/futbollocal/thumb/mdayan_rc1.jpg)

Thanks and great job!

Hi there,

Im working on a Proof of COncept regarding silverlight. I am especially wanting to proof the use of DeepZoom. I want to annotate for instance a rectangle on a particular image within the multi-image group. The problem I currently have is that the animation of the deepzoom, and my resizing and moving of the rectangle gets out of sync and then it just doesnt look that good.

Please see a primitive example here:
http://martycode.blogspot.com/2009/06/testing-my-deepzoom-page.html

Do you have any ideas as to how to fix this. I need to work on it ASAP :) Thanks a lot.

PS: I was thinking of maybe adding an INK-type overlay on each sub-image - how can I overwrite the sub-images and keep annimation in sync...

Go well,
Marthinus

Hi John,

Where have you seen the other dynamic tile solutions?

Thanks

How did I miss that! very good.

Having done something similar in Azure I just wonder how well this will work in the real world. I had serious problems with images that took up more then the 512MB memory allocated - large satellite images from NASA. The benifit of the Azure solution was it was one image per machine. How do you handle running out of memory if you're dealing with large images and many new requests?

Most deep zoom dynamic tile solutions I've seen proposed are window services listening for new files to be dropped into a folder and then tile them up in advance of the web application. This kind of strategy can also detect when an image is modified and update the tiles accordingly. That said I can see the benifits in having it inside your asp.net application.

It is fake links. It is not an example.

>> Next step is to do some caching, imagine you had a 2MB image and had 100 people asking for 100x100 tiles, you would load the 2MB image into memory 10,000 times.

It already solved. I'm locking image while decomposing, that is why for 100 people it would be done only once.

Great job here!

Next step is to do some caching, imagine you had a 2MB image and had 100 people asking for 100x100 tiles, you would load the 2MB image into memory 10,000 times.

That said this is an awesome way to get a bunch of small images into the MSI control, which is exactly what you said in the intro. Good work!

I haven't used any Silverlight 3 specific feature in this article. So it would also work with Silverlight 2.
