Some RGN requests failing. about iipsrv

Here's the log (level 10) for the request that produces the error:

CVT maximum viewport size set to 3000

Nothing after that.

Note that if I change slightly the RGN to RGN=0.700632,0.318253,0.027789,0.017951 I get a valid response with the expected region.

This only occurs with this one specific image? If so, yes, please send the image to me to test this out.

Hi, sorry I left this unanswered as I've used a work around since I discovered this bug.
Now we have a few projects based on IIPSrv and this issues is causing more trouble so please let me know if I can help you reproducing it.

I've just rebuilt the latets version of iipsrv today with kakadu 7.4.0 and the I can systematically reproduce the issue described above with that particular JP2 image. It also occurs with other images but the regions causing an error varies.

How can I send you the image file? It is pretty big and it is copyrighted so I can't give a public link to it.

Thanks in advance for your help.

OK, if you send a link to it to [email protected], I'll try to figure out what's going wrong

[ruven]

OK, I think I've found the problem. I've just uploaded a fix - please try it out and tell me if it works for all your problem images.

Working well now, thank you very much for the prompt resolution!
