I'm using openseadragon to display a pyramid (DZI).
The hi-res image is constructed at runtime and I want the OSD viewer to be updated during the hi-res image construction process.
In order to achieve that, I initialize the DZI hirarcy with blank images (white image). Then, during the construction of the hi-res image, I replace the blank images with new ones (in the server).
How could I update specific tiles on demand? The server can send back to the client information about tiles that are "raedy" (contains real image).
