Topic: IA 1.31 JPEG2000 problem

Hi,

it seems that 1.31 produces damaged jp2 files. When reopened in IA, there are wrong colors, or you get "Error in bitmap data". In 1.30 it was OK. These files can or cannot be opened in other programs supporting JPEG2000 format.

I uploaded the same photo losslessly saved by 1.30 and 1.31 onto the folder at url:
http://cid-5c7afa1d9502f86f.skydrive.li … /IA131TEST

The file sizes are the same, however there are some binary differences in the header.

Produced in Vista SP2. The same problems when running under Debian 4/Wine.

Re: IA 1.31 JPEG2000 problem

Yes, I can see that. Thanks for reporting. The strange thing is that it sometimes works - if you just same the same picture several times some of the files will be correct... That must be why I didn't notice before. The only difference is that they the JPEG200 DLLs were compiled with different versions of Visual Studio.

Anyone seeing this problem can get the old JPEG 2000 handler DLL here: (just replace the one in the IA folder)
