I do not see any reason to help that format to spread. It even does not support large files (> 4GB), so what advantages it has over the old TIFF with except of the new codec? When that format will become notable we can start implementing libtiff support for it. > From what I understand of the license, it should be possible to > include the HDPhoto support in libtiff.

Nope, I am reading the HDPhoto_eula.txt from the DPK distribution. It has a number of clauses conflicting with libtiff distribution terms. I can list some of them: " * Third Party Distribution. You may permit distributors of your Licensed Products to copy and distribute the Distributable Code as part of your Licensed Products, provided that your distributors are legally prohibited from modifying, and do not modify, the Distributable Code and/or the Licensed Product in a manner that causes the Licensed Product (or any third party product in which the Licensed Product is incorporated) to become non-compliant or incompatible with the HD Photo 1.0 file format (a.k.a. the Windows Media Photo 1.0 file format) as defined in the specification(s) provided in the software." "ii. Distribution Requirements. For any Distributable Code you distribute, you must * distribute the Distributable Code only as part of a Licensed Product; * add significant primary functionality to the Distributable Code in your Licensed Products;" (BTW, what does it mean: "significant primary functionality"?) "iii. Distribution Restrictions. You may not * include Distributable Code in malicious, deceptive or unlawful programs or products; * include Distributable Code in any program or product that is non-compliant or incompatible with the HD Photo 1.0 file format (a.k.a. the Windows Media Photo 1.0 file format) as defined in the specification(s) provided in the software; or * modify or distribute the source code of any Distributable Code so that any part of it becomes subject to an Excluded License. An Excluded License is one that requires, as a condition of use, modification or distribution, that * the code be disclosed or distributed in source code form; or * others have the right to modify it." Definitely, all these makes that source code not compatible with libtiff license and generally non-free. So the only option remains is an external linking. Best regards, Andrey -- Andrey V.
