Some tiles does not fit

[Ricky-Y]

I played around with the iipsrv and iipmooviewer on my mac, and I got them work. However, there is an issue that some tiles on bottom right corner does not fit. It happens when I use other images too. Let me paste it here:

IIP server is version 1.1 and iipmooviewer is the current version on github. Both server and viewer is running on mac OS Catalina. The .tif file is generated by

sudo vips tiffsave <input.jpeg> NationalPark.tif --tile --pyramid --compression deflate --tile-width 256 --tile-height 256

Any thought why it could be like this?

I used identify command in terminal to test if the original image was broken but it returned good result.

BTW, I was using protocol IIIIF for the view above, when I switched to the default IIP protocol, it works perfectly

@ruven Any thought?

It's a bug in the viewer code (not the server) - yes, use the IIP protocol for now. The server can simultaneously understand both IIP and IIIF APIs and remains IIIF compliant regardless, so it makes no difference if you use IIP with iipmooviewer.

@ruven Uh, is that bug due to the wrong size param in the tile request? The last tile should not be requested with !256,256 size since both width and height of the last tile is less than 256, is that correct?

Oh, I see the issue in viewer repo. Thanks for you reply!
