I have a question about the usage of jpeg2000-files with the Aspose.components. There are some legal concerns about using jpeg200-files, as only the core functions are free of licences.
can you guarantee us, that it is legally save for us to use jpeg2000-formats with the Aspose.Total.Net component?
Thank you and kind regards,
In case of Aspose.Imaging API, the implementation of JPEG2000 format is licensed under 2-Clause BSD license. This information is included in our Third party licenses file. You may please visit the link for details on 2-Clause BSD license.
we are not only concerned about the used library, but also on the patented jpeg-2000-format itself.
Let me try to clarify our concerns:
As the jpeg2000-group says, jpeg2000 is not completely license-free (no matter, which library is used!). So one day it might be the case, that the jpeg-2000-group, or any one else, who is envolved in the jpeg-2000-format might get the idea to ask for a license-fee on the jpeg-2000-format. He might ask you (Aspose), and what will you do? Can you guarantee, that you will handle this without any issues for us (i.e. ask us to pay for the license, or even stop handling jpeg2000-images, which might result in PDF-documents, where some information is missing, because some images are coded in this format).
If you have any questions, please don’t hesitate to ask.
Thanks a lot and have a nice weekend.
We are looking in to it. We will update you soon.
Please accept our apologies for getting back to you quite late.
Let’s start from Part 1 of T.800 (08/2002) Information technology – JPEG 2000 image coding system: Core coding system as we have previously confirmed that our implementation fits this recommendations. As it was noticed and mentioned by you that:
“JPEG 2000 is covered by patents, but the contributing companies and organizations agreed that licenses for its first part—the core coding system—can[clarification needed] be obtained free of charge from all contributors”.
This fact is confirmed by the fact that well known implementation of Jpeg2000 OpenJpeg is licensed under BSD license.From the other side in the above mentioned recommendations there is following notice
“INTELLECTUAL PROPERTY RIGHTS ITU draws attention to the possibility that the practice or implementation of this Recommendation may involve the use of a claimed Intellectual Property Right. ITU takes no position concerning the evidence, validity or applicability of claimed Intellectual Property Rights, whether asserted by ITU members or others outside of the Recommendation development process. As of the date of approval of this Recommendation, ITU had received notice of intellectual property, protected by patents, which may be required to implement this Recommendation. However, implementors are cautioned that this may not represent the latest information and are therefore strongly urged to consult the TSB patent database.”
So, from such viewpoint we could not warrant that use of our or any other Jpeg2000 implementation is completely risk free, but can state that we are applying reasonable efforts to protect our company and respectful clients. I hope the shared information will be helpful.
