Large jpg error

[XaviAure]

Hi Glen
I have been trying to use the tiler for large jpg images (65000 x 40335) but it keeps giving me errors. The largest size I managed to run was 30000 px. Is there a maximum size the tiler can run? Thanks for your help.

Zoom level 5
Exception in thread "main" java.lang.IllegalArgumentException: width*height > Integer.MAX_VALUE!

I'll have to investigate a different way of loading images but looking at that exception. The Integer.MAX_VALUE is 2,147,483,647 and the width x height you mention is (65000 x 40335) 2,621,775,000 which is bigger than the max value... Assuming iiif-tiler is given enough RAM it should process images with dimensions that multiple together are under the MAX_VALUE but this seems an artificial limit so Ill see if there is a way to get round it.

There is also another issue with the iiif-tiler for images which are bigger than 65k x 65k pixels as this is bigger than is allowed in the jpg standard but I don't think you've hit that issue yet.

Thanks for looking into it. I know about the 65k limit, the images were already resized to fall below that limit, that is why I thought there was some other error going on.
Thanks again.
