Hi guys, Just to clarify, the Public Use License Agreement for ER Mapper's ECW and JPEG 2000 codecs and the related SDK is not the same as the GPL. It's described as "GPL-style" to make it clear to potential licensees that it carries a copyleft restriction for anyone wanting to distribute software that uses it. It is true, and somewhat unfortunate, that it does not conform to the FSF's guidelines for "free" software. This is something that comes under regular review at ER Mapper. We could, for the most part, transfer the license to a straight GPL dual license, but we are somewhat concerned that the ECW format might be modified by third parties, creating format compatibility problems. Also, the SDK is a commercial product and its main focus is still commercial licensing. If anyone has further questions about the SDK's licensing, please fire away :-) Regards -- Tom Lynch Development, ER Mapper Phone: +61 (0) 434 929 287 Email: [email protected] Web: http://www.ermapper.com Forums: http://forum.ermapper.com _______________________________________________ Freegis-list mailing list [email protected] https://intevation.de/mailman/listinfo/freegis-list
