IIP crashes when processing larger JPEG2000 images with CVT JPEG with HEI < 129px

[filak]

It seems to me that this is very similar to https://github.com/ruven/iipsrv/issues/189

The problem shows both with IIP and IIIF protocols:

/fcgi-bin/iipsrv.fcgi?FIF=/e.jp2&HEI=100&CVT=jpeg

/fcgi-bin/iipsrv.fcgi?IIIF=/e.jp2/full/100,/0/default.jpg

However this pull request https://github.com/ruven/iipsrv/pull/233 fixes the IIIF call.

Hi @ruven, any updates on this ?

[ruven]

I've now merged the pull request (https://github.com/ruven/iipsrv/commit/ea84c761f723581ce8906f35b202b19cec373914). Can you please test and let me know if it everything now works correctly?

[filak]

Thank you, it works as expected.

[filak]

I need to reopen this, the issue still persists. @ruven would you mind if I send you the affected image ?

Sure, go ahead.

[filak]

OK, done, send to Your sourceforge.net email.

[ruven]

It turns out to have been due to a bug in iipsrv's OpenJPEG decoder. I've just committed a fix (https://github.com/ruven/iipsrv/commit/ffe319016e6b7de57778083a033b7b320e3a9247). Please test and let me know if there's still a problem

@ruven I still encounter bigger images which do not play nice with IIP protocol:

/fcgi-bin/iipsrv.fcgi?FIF=/xx.jp2&HEI=128&CVT=jpeg

(IIIF works fine in these cases: IIIF=/xx.jp2/full/128,/0/default.jpg)

I will try to send the image to your sourceforge.net email.

[ahankinson]

128, in IIIF is w,h -- you can try with IIIF=/xx.jp2/full/,128/0/default.jpg and see if that triggers it?

[filak]

Sorry, poor testing on my part...

This works: /full/,131/0/default.jpg

But bellow 131 it does not: /full/,130/0/default.jpg

[ruven]

Your xx.jp2 image works fine with the above requests on my machine. Are you sure you are using the latest iipsrv which includes the https://github.com/ruven/iipsrv/commit/ffe319016e6b7de57778083a033b7b320e3a9247 commit? Make sure you're using the latest code and maybe do a make clean before rebuilding.

If it still crashes, give me the last 10 lines from the iipsrv log file.

[filak]

Hmmm, maybe I did not update my fork before building... With the most recent version and after rebuilding everything works fine. Thank you!
