This is a current limitation of the JPEG2000 decoder. This third party library comes from Mozilla's pdf.js project. See these two related issues:

• pdf.js/issues/6365 (mozilla)
• image-JPEG2000/issues/4 (OHIF)

How to implement on decoder side?

They said it is easy to solve this problem..

I think "cornerstone" which is other library is working..

And it uses many third party library including wado, dicomparsr and decoders..

I think It could be integrated with dwv.

I don't care the quality of a dicom file..

I hope to just show a dicom image.

[taehun1214]

I have to this right now.. Could you let me know the progress? Please.. I really beg you..

[taehun1214]

please... any suggestions???

[ivmartel]

Sorry, I do not know how to fix the decoder, maybe best to ask @jpambrun directly.

[taehun1214]

At the moment, I asked him.. By the way, If I could ignore checking this exception, Is it possible??.. I really need this. And I just want to show the dicom image and I don't care the quality of the image..

[jpambrun]

I think the selectiveArithmeticCodingBypass COD should be easy to implement, but I don't have the time to investigate. You should consider using this Emscripten build of OpenJpeg : https://github.com/chafey/openjpeg. It is the reference implementation and should support all you need.

I created an issue to study the integration of openjpeg. Please comment there if you need.

[taehun1214]

ok. I really need.

[Mamta92]

Can I get to know the exact reason why it is failing? I'm also facing the same issue for a particular series.

@Mamta92 please use #718 for comments. As mentioned there, if you could share some data that would help.
