Long time listener, first time poster!
We’d like to create an html5 plugin that runs a serverside script that recreates the users current view from the source pano image. Ideally we’d like to reference the tiles the user is looking at (multires) instead of having to reference and process the entire pano image for such a small thumbnail. This way we can control the output size of the image centered around the point they're looking at in the pano, regardless of their browser size.
The ecard plugin works nice, but we’d like to abstain entirely from using flash and get around the performance bottlenecks of using the canvas image for the snapshot. It seems ipads and some phones have performance limitations and are just showing a black image when we use the client size snapshot of the canvas, plus we're at the mercy of their browser size for the final image
Where we're lost is how to reference the current ath and atv within the tiles that the user is currently looking at, as well as what tiles they are looking at when they request the snapshot.
Or is there a way we can limit the resolution when they request the snapshot, then put the resolution back after the image is done? We're using canvas's built in toDataURL function currently.
Hopefully some of the big guns can provide some wisdom...Klaus, Tuur, Sacha, VN, Michel, Jarreda, Sudarchikov?
