Jpeg2000 Lossless quality issue

[lambacini]

i try to load & view JPEG 2000 Lossless compressed image (1.2.840.10008.1.2.4.90). There seems to be a problem with the quality of the decompressed images. I tried compressing the images with two different libraries (fo-dicom & leadtools) but the result did not change. i added sample screenshots and dicom files related to the subject.

( does not appear to be a problem in older versions of CornerstoneWadoImageLoader )

Also, other viewers such as osirix, 3D Slicer, radiant do not seem to have a problem.

I have changed the software version to 3.1.2，it can resolve JPEG2000 Image.but UltroSound image cannot be resolved. Have you ever encountered situation like this?

i think there is a misunderstanding. If you look at my explanation, i wrote that while opening an issue, it was already working fine in old versions. Downgrading is not a permanent solution. because there are other problems caused by the old version.
