As far as this issue is concerned, there shouldn't be any difference between one or two pixels overlap. A two pixel overlap isn't really any different... Just thicker. I don't...

@zhengzho By the way, the WebGL patch is already good enough for you to try. Grab the branch from #2310 and build it. It would actually be helpful if you...

Interesting! The tile overlap is working fine, but the tiles aren't being drawn precisely in this case. You can tell the overlap is working if you zoom in on it....

Okay, it looks like this is the line: https://github.com/openseadragon/openseadragon/blob/3bbfbcbc0e136405e3f8ed95316d36255dba835f/src/tiledimage.js#L1624 Note that it's only doing it when your tile source has no overlap, so if your DZI did have an overlap,...

Indeed. We've been discussing that very issue over in https://github.com/openseadragon/openseadragon/issues/1683. I have a proposed patch, which is pretty much what you came up with, here: https://github.com/openseadragon/openseadragon/pull/1713 but we haven't merged...

Sounds good! I look forward to hearing your thoughts :-) And yeah, the subpixel rendering isn't directly related to this issue, but only because the current behavior avoids it. Like...

FYI, the new WebGL renderer that's in the works in #2310 fixes this issue! @karin-toth if this is still a concern for you, I'd love it if you could give...

I suppose we can close this now that the WebGL renderer has been released!

@swamidass If you want that fix sooner than later, you can do a build off of master. It'll probably be a while before we do another release, as we have...

A WebGL drawer (https://github.com/openseadragon/openseadragon/pull/2310) and a reworked cache system (https://github.com/openseadragon/openseadragon/pull/2407).
