@msalsbery , I see that you closed the Win8.1+IE11 issue (527) with the toolbar that I reported. Are you saying that the openseadragon libraries used on the demos here: http://openseadragon.github.io/examples/ui-toolbar/ and here: http://openseadragon.github.io/ are out of date? Are you saying that you were able to use the toolbar buttons with IE11 on Windows 8.1 on those pages?

I can see the bug on the demo pages, but I can't reproduce in the current code. I haven't signed off on it yet as far as my TODO LIST goes. Feel free to reopen it or I will when I'm back in front of a computer in a bit

I was the one who closed it, based on the conversation in the issue. I'll reopen.
At any rate, we generally close issues when they are fixed on the master branch, rather than waiting until they are released to the public website.
the version that's on the public website is from May 2014, so it's a bit behind what's on the master branch. @photomedia if you want to try the very latest, you can grab the repository and build it locally.

iangilman: I played a bit with the collections branch. Where can I find some infos on the world coordinates system?

@avandecreme I suppose I should write some! At any rate, it's just an arbitrary coordinate system… Use whatever numbers you'd like.
You can think of it as an extension of the earlier viewport coordinate system, which goes from 0 on the left to 1 on the right. Now just add a second image going from 1 to 2, and you've created a little row.

ok, but what defines how many pixels there are between 0 and 1? 1 and 2?

@avandecreme You mean image pixels? The images themselves define that. If the first image is 1000 pixels wide, all 1000 of those pixels go between 0 and 1. If the second image is only 50 pixels wide, those 50 pixels go between 1 and 2.
Images are laid out irrespective of their pixel density. You can have high resolution images next to low-resolution images.
Does that make sense?
