Horizontal tile borders visible when zoomed in

I’m brand new to OpenSeadragon, so pardon my ignorance. I’ve looked around to see if there is some option that might help me, but haven’t come up with anything.

I’m using OpenSeadragon (1.0.0) with FreeLib-Djatoka. When I zoom in on my image (at any depth), I see horizontal black stripes at my tile borders (top and/or bottom; see attached image below).

I’m invoking OpenSeadragon like:

OpenSeadragon({
  id : "freelib-djatoka",
  prefixUrl : "/images/",
  tileSources : [protocol + "://" + host + ":" + port + "/iiif/" + src + "/info.json"]
});

where iiif/413/info.json (generated by FreeLib-Djatoka) looks like:

{
  "@context":"http://library.stanford.edu/iiif/image-api/1.1/context.json",
  "@id":"http://localhost:8888/iiif/413",
  "width":2884,
  "height":2328,
  "scale_factors":[1,2,3,4,5],
  "tile_width":256,
  "tile_height":256,
  "formats":["jpg"],
  "qualities":["native"],
  "profile":"http://library.stanford.edu/iiif/image-api/1.1/compliance.html#level1"

}

What am I doing wrong? Thanks!

@sindhuri-rotte-dasari I’m sorry, I’m not sure how we resolved this. We upgraded at some point in the last 6 years to OpenSeadragon 1.1.1 and are still on that version, and are not seeing this issue anymore, so maybe that was the fix?

If you are using a current version of OpenSeadragon (like 2+), I would probably suggest opening a new issue. If you happen to be using the very old 1.0.0 or earlier, maybe try upgrading to a later 1.x version?

Interesting. Is there transparency in the image? Do you have it publicly available where I can take a look?
