Hi, just wanted to ask if it's expected that when saving an image using the JPEG2000 lossless option, some values differ from the original image. Not a whole lot, but there are some differences.
However, this only happens in 32-bit applications using the Delphi code. Using ielib32.dll or ielib64.dll, there are no differences.
Thanks in advance.

Hi Ray
Are you referring to changes to the meta-data?
If so, then that is expected.

It's the image itself. I'm attaching a sample project with the image I'm using. If I run the test (32-bit build) with ielib32.dll, I have 0 differences between the original DICOM image and the saved DICOM image. If I remove ielib32.dll, I have 30k+ differences.
Thanks in advance.

Thanks, we will investigate. However you should use ielib if you need JPEG2000 support. It is a much improved implementation.
