For example: If you’re first looking at an image in OSD, and the first tiles that are loaded allow the image to fit to your viewport. Now, if you zoom way in, when you zoom out, how does OSD access the already downloaded tiles?  \r\n3)\tWhat’s the standard for the highest zoomed in level OSD can handle or allow? Is there a certain zoom level (if the resolution gets to low) that OSD won’t show because the quality is to bad? \r\n4)\tCan you set how many levels get loaded first? What is the standard set for how many levels get loaded first? \r\nI can’t express how much you guys are helping me!  Thank you so much! \r\n"},"comment":{"url":"https://api.github.com/repos/openseadragon/openseadragon/issues/comments/338615942","html_url":"https://github.com/openseadragon/openseadragon/issues/1311#issuecomment-338615942","issue_url":"https://api.github.com/repos/openseadragon/openseadragon/issues/1311","id":338615942,"user":{"login":"zloysmiertniy","id":399351,"avatar_url":"https://avatars2.githubusercontent.com/u/399351?v=4","gravatar_id":"","url":"https://api.github.com/users/zloysmiertniy","html_url":"https://github.com/zloysmiertniy","followers_url":"https://api.github.com/users/zloysmiertniy/followers","following_url":"https://api.github.com/users/zloysmiertniy/following{/other_user}","gists_url":"https://api.github.com/users/zloysmiertniy/gists{/gist_id}","starred_url":"https://api.github.com/users/zloysmiertniy/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/zloysmiertniy/subscriptions","organizations_url":"https://api.github.com/users/zloysmiertniy/orgs","repos_url":"https://api.github.com/users/zloysmiertniy/repos","events_url":"https://api.github.com/users/zloysmiertniy/events{/privacy}","received_events_url":"https://api.github.com/users/zloysmiertniy/received_events","type":"User","site_admin":false},"created_at":"2017-10-23T10:26:01Z","updated_at":"2017-10-23T10:26:01Z","author_association":"NONE","body":"I would like to add a question to understand OSD better:\r\nIs there a fixed range for zoom level, or is it  depending on the image? Is it possible to say like I want only 5 levels, even if there are more? I ask because I want to use this to dispaly images where usually you have 2 times the magnification in every step, you start by 2.5, then 5, 10, 20, and 40. so even if there are more tiles created by VIPS I would like onl that amount of levels. Do you have any insight on this? \r\n\r\nThank you!"}}
