I’ve had some time to experiment more with DeepZoom, and was able to provide the Expression Composer team with one of the projects that was causing me problems.
If you nest enough images, the images become “small” enough that the encoder doesn’t know what to do (and in my case, did nothing). I have found that this seems to occur for me once I get to about 4 images or so, but only if they are overlapping. If I scale the images and position them next to one another, Composer will export the files as expected.
This led to a different problem, however. When placing the images next to one another so that each is smaller than the previous one, by the time I’m zoomed in on the last of 9 images, it’s blurry and illegible. This one seems to be more of an issue with the rendering engine, because the JPG the multiscale image control is using looks great. It *looks* like you’re zoomed way in on an image, but it’s not resolving to the smooth version.
These kinds of issues are to be expected with pre-release software, of course. I’m really excited about this feature though. There’s a ton of possibility there - I’m looking forward to updates as they become available!
