Thank you for report this! What browser are you running on? Can you share a link to a repro project? What tool are you using to gauge the memory size?...

Looks like there hasn't been any action on this bug; it's just waiting for someone to volunteer to look into it. Would you be interested?

Interesting! Here's what I get when I run `grunt coverage`: ``` (node:4838) Warning: Accessing non-existent property 'VERSION' of module exports inside circular dependency (Use `node --trace-warnings ...` to show where...

Sure enough, if I remove my `coverage` folder, I now get the same result as you! I haven't worked with Istanbul here in a long time; I wouldn't be surprised...

@SebDelile That certainly seems like an improvement. Would you be up for making a PR with that fix?

Yes, you'll need to convert them and store the results on your server (or somewhere else your app can access). There are a number of tools available: https://openseadragon.github.io/examples/creating-zooming-images/ I recommend...

@tofetpuzo Sure, I believe Deepzoom.py can also convert TIFF to DZI. It's a fine option, if it fits better with your system.

For the record, I wouldn't say DZI is outdated... It's a perfectly lovely simple format. IIIF is indeed more flexible, though!
