Re: How do you properly code an image viewer?

I only looked at one page -- but the OCR was terrible. There were only random words recognized.

While it doesn't necessarily meet WCAG, I would say, don't worry about the viewer, as far as blind people go if it only works with graphical images. It doesn't matter!

Subject: [WebAIM] How do you properly code an image viewer?

I'm thinking of a site like Historic Oregon Newspapers where content is presented in a way that is fundamentally not usable by a blind person (e.g., https://gcc01.safelinks.protection.outlook.com/?url=https%3A%2F%2Foregonnews.uoregon.edu%2Flccn%2Fsn84022644%2F1878-08-30%2Fed-1%2Fseq-1%2F&amp;data=02%7C01%7Cdavid.b.andrews%40state.mn.us%7C2562f90b04104f74e5c608d72d72e8ca%7Ceb14b04624c445198f26b89c2159828c%7C0%7C0%7C637027843860613303&amp;sdata=jFwgdd2riZdTnw%2BZwNrOVSjx5MetgwhKY0tH97ii1CM%3D&amp;reserved=0)

We provide an OCR capture, which is unfortunately not great, but the best we can do without hiring thousands of people to write transcripts of each page. But the viewer for those pages is something that cannot be used by a blind person, period. How do we handle that? Open Seadragon uses a canvas element, and that viewer can't be described textually (imagine trying to describe one part of a zoomed-in page). I'm just at a loss for how best to handle a site like this.
