Can I initiate a MultiscaleImage in another MultiscaleImage?
At first I have to say, this is a very great tool with future.
The next time I have to do my diploma thesis. I want to show the map of a city in flashplayer. When I zoom in I would zoom in special buildings in the city.
My question is: Can I initiate a MultiscaleImage in another MultiscaleImage to provide the more datails only in the building or is this a stupid consideration?
Thanks!
Manfred

Inappropriate?Manfred,
Glad you like OpenZoom. No, your idea is not stupid at all. However, you won't achieve this by nesting MultiScaleImage components but rather by writing your own renderer which changes it's representation at a certain scale. Have a look at the OpenZoom, Is This Your Luggage? example:

Inappropriate?Daniel,
thanks for your reply. I think I'll do it with several layers (MultiScaleImages) with same extents. Then I can switch on and off floors of a building. Another short question: What is the class ImagePyramidRenderManager for and why is it not commented in the documentation?
Thank you again!
Cheers,
Manfred
I’m happy

Inappropriate?Manfred,
Thanks for asking! The ImagePyramidRenderManager is the heart of the OpenZoom SDK. It is responsible for orchestrating the loading, caching & rendering of multiscale images as well as collections of multiscale images, specifically the image tiles. It's where a lot of the heavy-lifting is happening and it has many options which allow you to fine-tune it to your particular application.
For example, you can set the cache size, define how many tiles get loaded simultaneously both during viewport transformations as well as when the viewport is static, the duration of the tile blending...
You might be wondering why I'm not exposing any of that functionality? Well, I'd like to eventually but documenting & exposing something always comes with certain commitments I'm not quite willing to make at this point.
Feel free to poke around in it and let me know if you'd like to know how certain parts work in particular.
Cheers,
Daniel
